SPRING
“The winter wind has lost much of its cutting edge,” wrote naturalist John Madson about the midwestern spring. “From then until hard frost, there will be no time when the prairiescape is not enameled with flowers of some kind. From the first pasqueflowers of March to the towering sunflowers of October, the tallgrass prairie will never be without flowers.”1 March brings the first pasqueflowers, but for another twentieth-century nature lover, Patricia Duncan, “the month of May is the apex of the spring prairie. Green is taking over, bird song is taking over, and insects are taking over. Wildflowers such as golden alexanders, birdsfoot violets, prairie rose, spiderwort, purple milkweed . . . are taking over.”2 Midwestern spring flowers had nineteenth-century admirers, too. “The earth in the woods is covered with May-apples not yet ripe, and in the enclosed prairies with large fine strawberries, now in their perfection.” Also beautiful are “the red lily, and the painted cup, a large scarlet flower,”3 wrote William Cullen Bryant. Visiting Illinois to be with her sister, Eliza W. Farnham wrote, “The landscape grows more beautiful every day. The prairie puts on its richest garb about the first of June. The painted cup, moccasin flower, and geranium, come out.”4 Observing spring while touring the Great Lakes in 1843, Sarah Margaret Fuller wrote, “In the wood grew not only the flowers I had before seen, and wealth of tall wild roses, but the splendid blue spiderwort, that ornament of our gardens,” and the “most delicate flowers,” including “a familiar love, the Scottish harebell, the gentlest, and most touching form of the flower-world.”5
After our long winters, midwesterners look forward to beautiful spring flowers. It’s too bad that many commercial garden centers, catalogs, and public displays of spring flowers feature ornamental plants from Europe and elsewhere. Native spring flowers are just as beautiful, and their nectar attracts bees and butterflies. Midwestern wildflowers also play an essential role in butterfly reproduction, because these insects lay their eggs only on host plants that the caterpillars, or larvae, can digest, which most often are native plants. Several fritillary butterfly species lay their eggs on or near native violets, sometimes when the host plant has already dried up. The parsnip, or black swallowtail, butterfly (Papilo polyxenes) and the Missouri or Ozark woodland swallowtail butterfly (P. joanae) lay their eggs on plants of the Carrot family, such as spring’s golden alexanders (Zizia spp.). America’s best-known butterfly, the milkweed or monarch butterfly (Danaus plexippus), lays her eggs on milkweeds (Asclepias spp.); the spring bloomers among them include blunt-leaved, green comet, and purple milkweed. As is typical of more than 90 percent of insects, most butterflies are restricted in their diets to native plants, because they “have not developed the enzymes” required to digest the leaves of nonnative plants.6

The Midwest’s spectacular show of native spring flowers coincides with another extraordinary regional event. As northern birds, like the juncos (p. 207) that spend the winter in the Midwest, depart north for the summer, tiny, gorgeously colored warblers, robins, native sparrows, woodpeckers, and hummingbirds fly in by the millions from winter homes as far away as South America. At the end of their long journeys, the migratory birds begin to reproduce and seek tiny insects and caterpillars to feed their young, as do cardinals, chickadees, and other year-round residents. For birds, the native spring flowers play an essential role: hosting a variety of insect caterpillars and attracting quantities of tiny insects.
Many early spring flowers are ephemeral, so they take advantage of available sunlight before it is blocked by leafed-out plants. This brief window of opportunity attracts pollinators. Frequent visitors include various bee species, some just emerging from their underground wintering quarters. Some bees, such as honeybees and bumblebees, are generalists. Others, like the tiny, solitary bees called oligoleges, are specialists. Codependency requires these insects to pollinate specific species/genera of flowers. If a population of specialist bees fails to locate its special flowers, it cannot survive. The loss of one native bee population puts existing clumps of the beedependent flowers at risk.
Many insects contribute to the spring insect tapestry, but for native plants, none are more important than the ants. Wild ginger, blue cohosh, goldenseal, twinleaf, bloodroot, and trillium are some of the many native woodland spring flowers that depend on ants to distribute their seeds, and not on wind (as do some flowers and most grasses), because trees block the wind. The ants are attracted to the plant seed’s edible fleshy protein-rich appendages, or elaiosomes, which they carry to their nests to eat later. “After the ants have consumed the elaiosomes, they take the seeds to their waste disposal site, and ‘plant’ them in this nutrient rich environment.”7 Ants have been observed carrying wildflower seeds 30 feet away from a plant.8 Like bees, ants are an example of codependence, which benefits both parties and has existed since time immemorial. Wasps and mammals also perform this vital seed dispersing. Introduced nonnative ants may enter into or disrupt these mutualistic interactions between numerous plants and other insects.9
Another force disruptive to the mutualistic interactions between native plants, butterflies, and other insects is spring cleanup. Most homeowners give little thought to this modern-day ritual. We may notice that there seem to be fewer butterflies, fireflies, and birds around, but we rarely connect this circumstance to our gardening practices. Yet, the leaf litter that naturally mulches and fertilizes the soil holds insects in various stages of their lives. Removing these layers and/or covering them with sterilized mulch from the hardware store inhibit the growth of native woodland plants. It deprives robins, native sparrows, and other birds of insect food. It also deprives baby firefly or lightning bug (really beetle) larvae that live in the soil of the worms, snails, and slugs they eat, preventing their development into the adult fireflies that add magic to our summer evenings. Cutting host plants down too early kills the baby butterflies that overwintered as larvae or pupae. Gardeners who leave host plants in place through late spring help overwintering butterflies successfully reproduce. There is also the possibility of observing the emergence of adult butterflies that spent the winter there in their other stages of life. Leaving leaf litter intact enables gardeners to observe the robins, native sparrows, and other spring migrants that search for dormant insects, worms, and other bugs. Natural leaf litter enhances the beauty of woodland wildflowers that grow in soils rich in natural mulch. Choosing native host plants and conducting suitably restrained spring cleanups, including not using pesticides, are easy techniques for gardeners who love butterflies, fireflies, and birds and hope to see them prosper.

The benefits offered by native flowers, such as providing nectar and pollen and serving as butterfly reproduction sites, are rarely equaled by introduced flowers. For gardeners interested in fostering bees, birds, and butterflies by planting native spring flowers to replace introduced (that is, exotic, nonnative) spring flowers, we offer the following suggestions.
Nonnative:
AJUGA, BUGLEWEED. Family: Mint (Lamiaceae). Genus: Ajuga (A. reptans). There are other species and cultivars. Origin: Europe. Height: 6–12 inches. Ornamental Attributes: Bluish flowers late spring and summer. Cultivars may have purple or multicolored leaves. Cultivation: Partial shade. Well-drained soil. Can be a persistent weed. Invasiveness Note: Naturalized or invasive in much of the Midwest.

BISHOP’S CAP, TWOLEAF MITERWORT. Genus: Mitella (M. diphylla). Height: 1 foot. Ornamental Attributes: Clusters of fringed delicate fairy-like flowers bloom for a month April to June. “Under a glass the starry blossoms of the Mitella become objects of wonderful beauty; in fact, they suggest the delicate crystals of snow,” wrote Harriet Keeler.12 Clumps of heart-shaped long-lasting evergreen leaves. Cultivation: Light or partial shade. Medium moist or average well-drained garden soil. Each flower is replaced by an open capsule that contains many small seeds, which are distributed by raindrops. They strike the capsule and cause it to bend, flinging some of its seeds. Nature Note: Pollinators include pollen-eating syrphid flies (p. 14) and species of short-tongued bees that seek nectar and collect pollen for their larvae.
More Native Alternatives:
COMMON CINQUEFOIL. Family: Rose (Rosaceae). Genus: Potentilla (P. simplex). Height: Mat-forming. Ornamental Attributes: Bright yellow flowers April to June. Cultivation: Sun/light shade. Dry soil. Nature Note: Small butterflies seek the nectar. The endangered Karner blue butterfly (Plebejus melissa) uses common cinquefoil “as a nectar source when available.”13 Its primary visitors are small bees and beneficial flies. The larvae of a gall wasp (Gonaspis sp.) forms galls on the stems that are sought by birds, including woodpeckers, such as northern flickers,which eat the larvae.

Native Alternatives:
FRINGED BLEEDING HEART, EASTERN BLEEDING HEART, WILD BLEEDING HEART. Family: Fumitory (Fumariaceae). Genus: Dicentra (D. eximia) Height: 6 inches to 1 foot. Ornamental Attributes: Racemes of deep pink heart-shaped flowers spring through fall. “A more floriferous species than common bleeding heart when optimal growing conditions are provided.”14 Lacy often silvery-looking leaves remain attractive until frost. Foliage conceals empty spaces left by ephemerals. Masses of wild bleeding heart are spectacular. Cultivation: Sun/part shade. Moist soil. Nature Note: Wild bleeding heart attracts small insects that in turn attract hummingbirds (p. 10) and nesting birds; DUTCHMAN’S BREECHES (D. cucullaria). Height: 5–9 inches. Ornamental Attributes: Creamy white, waxy heart-shaped yellow-tipped ephemeral flowers April, May. Distinctly dissected blue-green leaves create clumps. Name Note: Derives from inflated spurs suggestive of legs of tiny pantaloons seen “anklesup”;15 SQUIRREL CORN (D. canadensis). Height: 6–12 inches. Ornamental Attributes: Flowers and leaves resemble Dutchman’s breeches and smell somewhat like hyacinths. Roots resemble grains of yellow corn.
Fringed bleeding heart (Dicentra eximia)
PALE CORYDALIS, ROCK HARLEQUIN. Genus: Corydalis (C. sempervirens). Height: 6–24 inches. Ornamental Attributes: Showy yellow-tipped single-spurred pink flowers. Cultivation: Sun. Dry soil. Nonnative Note: Do not confuse with the European yellow Corydalis (C. lutea). Nature Note: Spring flowers have a brief window of opportunity in which to attract pollinators, so they generally welcome most insects, but exceptions include Dutchman’s breeches, squirrel corn, and Corydalis, whose long spurs make reaching nectar a challenge. Bumblebees have long tongues that reach the nectar, but shorter-tongued honeybees don’t, so they gather the pollen. However, smaller bees sometimes poke holes in the sides of a bloom to access the nectar and so bypass pollinating the flower. The edible oily appendages of Corydalis seeds (elaiosomes) attract ants (particularly Pheidole bicarinata), which help to disperse the seeds. Hummingbirds visit all these flowers. Mammalian herbivores avoid the foliage.

CROCUS. Family: Iris (Iridaceae). Genus: Crocus (C. luteus). Origin: Middle East, Mediterranean. Holland is famous for exporting Dutch or giant crocus (C. vernus) and snow crocus (C. Tommasinianius, C. chrysanthus) that originated in the Middle East. Height: 2–12 inches. Ornamental Attributes: Yellow, white, lavender, purple flowers bloom briefly in March, April. Cultivation: Sun/light shade. Welldrained soil. Ephemerals die when mowed before the leaves naturally die. Overcrowding causes decline. Nature Note: Squirrels, deer, chipmunks, mice, rabbits, skunks (in search of insects, worms, and organic fertilizers), voles, and birds dig up crocuses and some of these animals eat the corms/bulbs. Gardeners combat this with homemade and commercial repellents, protective barriers, plastic owls, and other ingenious deterrents.
Crocus (Crocus luteus)
Native Alternatives:
AMERICAN PASQUEFLOWER, WILD CROCUS, BLUE TULIP. Family: Buttercup (Ranunculaceae). Genus: Pulsatilla (P. patens) (formerly included in the genus Anemone). Height: 2–12 inches. Ornamental Attributes: Considered to be harbingers of spring. Large, delicate orange-centered blue-violet, sometimes white, flowers from March to May. Feathery seed heads. Hairy stems and leaves protect the plants from chilly early spring weather. “These are one of the first and most spectacular prairie flowers of spring.”25 Cultivation: Sun. Well-drained, dry to medium soil. (Best in sandy soil.) Nature Note: Bees eagerly seek the pollen produced by these early blooming flowers. The foliage does not interest mammalian herbivores.
PRAIRIE SMOKE, LONG-PLUMED PURPLE AVENS, OLD MAN’S WHISKERS. Family: Rose (Rosaceae). Genus: Geum (G. triflorum). Height: 4–16 inches. Ornamental Attributes: Showy, nodding pink to reddishpurple flowers in May, June. Feathery plumed fruits. Evergreen leaves turn red in fall. Cultivation: Sun, light shade. Dry to average garden soil. Note: Threatened in parts of the Midwest. Nature Note: The flowers look as though they are still in bud stage, so small bees crawl inside to get the nectar and pollen. As an early-flowering plant, it is an important food source for insects emerging from hibernation. See Lewis and Clark note in the appendix.
American pasqueflower (Pulsatilla patens)
BLOODROOT. Family: Poppy (Papaveraceae). Genus: Sanguinaria (S. canadensis). Height: 6–10 inches. Ornamental Attributes: Brilliantly white, daisy-shaped flowers bloom briefly late February to May. “One of the most beautiful of American wild flowers.”26 “Bloodroot is a good example of the continued blurring of the distinction between wild flowers and garden plants.”27 Lobed leaves create groundcover-like colonies. Broken stalks produce red juice. Though considered ephemeral, the foliage often persists to frost in moist soil. Cultivation: Light shade. Well-drained, dry or moderately moist soil. Nature Note: Ants collect, eat, and spread the seed’s elaiosomes or appendages. Butterflies seek nectar but search in vain; the flowers offer only pollen, sought by beneficial flies and beetles that in return pollinate the flowers. Mammalian herbivores rarely eat the foliage. Historical Note: In the 1600s, French explorer Samuel de Champlain observed that the root of our native bloodroot “makes a crimson dye.”28

More Violet Native Alternatives:
ALPINE VIOLET, LABRADOR VIOLET (V. labradorica). Height: 3–6 inches. Ornamental Attributes: Weeks of bright lavender flowers. Purplish-green foliage looks good all season; BIRDSFOOT VIOLET, PANSY VIOLET (V. pedata). Height: 6 inches. Ornamental Attributes: “The violet flowers are spectacular.”29 Bloom April to June, and all summer if regularly watered. Deeply lobed leaves. Cultivation: Sun. Dry well-drained soil; PRAIRIE VIOLET (V. pedatifida). Purple flowers April to June. Grass-like leaves. Medium soil; DOWNY YELLOW VIOLET (V. pubescens). Yellow flowers April to June; MISSOURI VIOLET (V. missouriensis). Purple flowers April, May. Note: Some violet species are endangered or threatened in parts of the Midwest. There are many species of wild perennial native violets, including white and bicolored, that are commercially available. Nature Note: Wild perennial native violets are the sole host plants for many butterflies including the Aphrodite fritillary (Speyeria aphrodite), regal fritillary (Speyeria idalia), silver-bordered fritillary (Boloria selene), and meadow fritillary (Boloria bellona), which is “attracted to gardens that are near wet meadows.”30 Native violets are the sole host plants for many species of greater fritillaries, including the great spangled fritillary (Speyeria cybele). This butterfly’s caterpillars feed by night and hide by day. By the time the female lays her eggs on or near the larval host plants in the summer, they have often died back. This large butterfly “frequently stops to nectar, especially at milkweeds, where several adults can be found at one time on a single flowerhead.”31Violets are among the preferred host plants for many fritillary butterfly species,, including the variegated fritillary (Euptoieta claudia). Violet nectar attracts many species of adult butterflies. The cobweb skipper (Hesperia metea) prefers birdsfoot violet nectar. Violets are pollinated by an oligolege bee, Andrena violae, a specialist in violets and wood sorrel. Ants carry violet seeds to new locations, fulfilling the vital role of seed dispersal. Solitary bees (among other insects) pollinate violets. When birdsfoot violet fruits become ripe, they are explosively ejected up to 15 feet.32 Migrating birds feed their young with enormous quantities of the tiny insects violets attract. Hummingbirds (p. 10) visit violets for both nectar and small insects. Nonnative Note: Do not confuse native violets with the common European/English violet (V. odorata).

YELLOW TROUT LILY, DOGTOOTH VIOLET. Family: Lily (Liliaceae). Genus: Erythronium (E. americanum). Height: 4–12 inches. Ornamental Attributes: “This little spring lily of the woodlands is a fascinating plant.”33 Showy yellow long-blooming flowers from March to May. Leaves are often variegated. “They [trout lilies] are, of course, most effective when seen in large congregations, fluttering and dancing in the breeze, like the Daffodils.”34 Cultivation: Dappled sunlight. Moist, well-drained soil. These ephemerals create impressively large colonies that live three hundred to four hundred years; WHITE FAWNLILY, TROUT LILY (E. albidum). Note: Trout lilies are endangered in parts of the Midwest. Nature Note: Trout lilies attract butterflies, including skippers. The primary pollinators are nectar-seeking longtongued and short-tongued bees. Honeybees and short-tongued bees collect the pollen. Trout lilies have a specialist bee, the oligolectic trout lily bee (Andrena erythroni). White-tailed deer damage is usually minor because of the low stature and ephemeral nature of the foliage. Note: See John Josselyn note in the appendix.

Average garden soil; HAIRY ANGELICA (A. venenosa); SWEET CICELY, p. 49; Summer bloomers: MARYLAND BLACK SNAKEROOT, p. 154; COW PARSNIP, p. 154; RATTLESNAKE MASTER, p. 122. Nature Note: The Parsley family is the sole host for the Missouri/Ozark woodland swallowtail (Papilio joanae), whose larvae have been found on meadow parsnip, yellow pimpernel, and golden alexander, and the parsnip or black or eastern black swallowtail (Papilio polyxenes). Swallowtails produce two or three broods, and any pupae that overwinter on or near Parsley family foliage emerge as adults in April and May. A variety of native Carrot/Parsley species extends the breeding season for these butterflies. Leaving the host plants in place through spring enables any overwintering pupae to survive. Blooms of plants in the Parsley family attract adult butterflies like the pearl crescent (Phyciodes tharos), eastern tailed-blue (Everes comyntas), American copper (Lycaena phlaeas), and clouded sulphur (Colias philodice). The inconspicuous tiny black bee Andrena ziziae is a golden alexander specialist. Nonnative Invasive Note: Do not confuse native Parsley family flowers with the nonnative yellow wild parsnip (Pastinaca sativa) or white Queen Anne’s lace (Dacus carota), both invasive in the Midwest. Do not confuse native angelicas with European garden angelica (A. archangelica) or Japanese angelica (A. elata), both invasive in parts of the Midwest. Dill, Parsley, and Fennel are also nonnatives that are invasive in parts of the Midwest.

GOLDEN RAGWORT. Family: Aster (Asteraceae). Genus: Senecio, Packera (S. aureus or P. aurea); PRAIRIE RAGWORT (S. or P. plattensis). Height: 1–3 feet. Ornamental Attributes: “The Golden ragwort stands as a surprise and an astonishment among the flowers of early spring, it is so deeply, so goldenly yellow.”37 One-inch blooms May to July. Slowly creates colonies. Cultivation: Sun/light shade. Golden Ragwort is more shade tolerant than some other ragwort species. Wet, medium, or dry soil. Hay Fever Note: Ragwort is not ragweed and does not cause hay fever. Nature Note: Some ragwort species host the northern metalmark butterfly (lephelisca borealis). Pollinators include beneficial flies (syrphid flies, tachinid flies, thick-headed flies) and small bees such as little carpenter, nomadine cuckoo, green metallic, and other halictine bees. Golden ragwort hosts the “gem” moth (Orthonama obstipata). Mammalian herbivores usually don’t bother this plant.
YELLOW STARGRASS, COMMON GOLDSTAR. Family: Lily (Liliaceae). Some experts place this flower in the Daffodil family (Amaryllidaceae). Genus: Hypoxis (H. hirsuta). Height: 3–12 inches. Ornamental Attributes: Clusters of “bright yellow six-pointed starry flowers, greenish on the undersides are hardly ever out of bloom from . . . May until the frosts have silenced them.”38 This reliable perennial has grass-like leaves. Cultivation: Sun/light shade. Well-drained average garden soil. Nature Note: This flower is cross-pollinated by small female pollen-collecting bees, interesting and beneficial flies, and pollen-feeding beetles.

HOARY PUCCOON. Family: Forget-me-not, Borage (Boraginaceae). Genus: Lithospermum (L. canescens). Height: 6–18 inches. Ornamental Attributes: Dense clusters of bright yellow to deep orange flowers April to June. Gray-green, white-down-covered leaves. Cultivation: Sun. Dry or medium soil. Native American Note: Natives extracted red dye from the roots of this “most famous of the Indian puccoons (dye plants).”40 Nature Note: “Hoary puccoon is the primary nectar source for spring grassland skippers like the cobweb skipper (Hesperia metea),”41 whose hosts are little and big bluestem grasses. It also attracts dusted skipper (Atrytonopsis hianna), which lays her eggs on big bluestem grass and spends the winter there. Hoary puccoon attracts butterflies, longtongued bees, and skippers, including the duskywing skipper (Erynnis spp.) and the common sootywing (Pholisora catullus). Spring-season bee flies, including the giant bee fly (Bombylius major), visit the flowers.

WILD LUPINE, SUNDIAL LUPINE. Family: Pea/Bean (Fabaceae, Leguminosae). Genus: Lupinus (L. perennis). Height: 2 feet. Ornamental Attributes: This blue alternative to daffodils features spectacular long-lasting fragrant blue-purple flowers April/May to midsummer. Spoke-shaped leaves. Small hairy seedpods. Cultivation: Sun. Tolerates light shade. Well-drained or dry soil. Prefers loose, sandy soil. Note: Threatened in parts of the Midwest. Nature Note: Sole host plant for the endangered Karner blue butterfly (Plebejus Melissa) (p. 16). This butterfly’s eggs remain on its host plant over the winter; disposing of host plants that hold overwintering butterfly eggs kills the eggs. In spring, the larvae are tended by ants attracted by the honey glands and tentacles of the larvae. Dotted mint, spotted beebalm (Monarda fustulosa) (p. 86) is this endangered butterfly’s favorite nectar. For the best Karner blue results, seek out local nurseries that carry wild lupine derived from state or local plants, because research suggests that, “Michigan’s Karner blue butterflies will not lay eggs on Wisconsin’s wild lupine.”42 Wild lupine also hosts yellow butterflies (called sulphurs) and blue butterflies including eastern tailed-blue (Cupido [Everes] comyntas) (p. 34), and west of the Mississippi River, silvery blue (Glaucopsyche lygdamus). The adult butterflies seek the nectar. Wild lupine also hosts Persius duskywing (Erynnis persius) and the frosted elfin (Callophrys irus) (p. 112), whose pupae overwinter on their host plant or in leaf litter and which appear as adults in April and May. Wild lupine has been planted as part of Karner blue butterfly conservation efforts, and it seems to be helping them, as well as other endangered butterflies.43 Wild lupine also hosts numerous other species of butterfly throughout the Midwest, including the gray hairstreak (Strymon melinus), whose pupae overwinter on the host plants. Blue flowers attract bees, which are blind to red. Bumblebees (p. 18) are lupine’s most effective pollinators. Invasiveness Note: Hybridization with other species, especially Washington lupine (Lupinus polyphyllus)44 and cultivars such as ‘Rainbow’ and ‘Russell’ lupines, is eliminating stands of native wild lupine. This deprives the endangered Karner blue butterfly (and the other endangered butterflies that lay their eggs on wild lupine) of reproduction sites.

DAME’S ROCKET, WILD PHLOX. Family: Mustard/Cabbage (Brassicaceae, Cruciferae). Genus: Hesperis (H. matronalis). Origin: Europe, Central Asia. Height: 2–3 feet. Ornamental Attributes: Pink, purple, or white flowers May to July that resemble a phlox.45 Long seedpods. Cultivation: Sun/light shade. Medium or moist soil. Vigorous self-seeder. Goes dormant in summer, creating large gaps. Invasiveness Note: Naturalized or invasive in much of the Midwest. “Dame’s rocket was introduced as a garden plant during the Colonial period.”46 It was a popular Midwest garden flower for hundreds of years and still is. In 1992, responsible garden experts called it a “good garden plant.”47 In 1996, the Brooklyn Botanic Garden reported, “A few, like dame’s rocket, right now appear to be only slightly invasive but are on weed experts’ ‘to watch’ lists because it often takes decades for a plant to begin spreading out of control.”48 The Brooklyn Botanic Garden’s 2006 Native Alternatives to Invasive Plants showed dame’s rocket as invasive in 11 states, some in the Midwest. USDA Plants identifies this plant as a noxious weed in 46 states. Note: Because dame’s rocket is often included in “wildflower” seed packets, they should not be purchased and if received, should be discarded.

Skunk cabbage (Symplocarpus foetidus)
SKUNK CABBAGE. Genus: Symplocarpus (S. foetidus). Height: 1–3 feet. Ornamental Attributes: Keeler wrote, “The first flower of our northern spring . . . has no great beauty that one should desire it, but is unusual in form and interesting in character.”50 Its many small, inconspicuous greenish-yellow to dull purple flowers are enclosed by a large round green-spotted purple shell-like sheathing (spadix) February to April. If crushed, the large cabbage-like leaves produce an odor reminiscent of skunk. Bright scarlet berries. These plants are “wonderfully architectural,” and their “fragrance is exaggerated.”51 Cultivation: Sun/light shade. Moist soil. Occur naturally in wet soil. Perfect for low wet spots. Nature Note: Flies mainly pollinate the flowers, including flesh flies (Sarcophagidae), carrion flies (Calliphoridae), and various gnats attracted by the carrion-like appearance and odor of the flowers enhanced by the increased temperature maintained within the spathe during early spring. Skunk cabbage hosts the cattail borer moth (Bellura oblique) and ruby tiger moth (Phragmatobia fuliginosa). Spiders lurk within the spathe feeding on visiting insects. Snapping turtles are one of the few herbivores that eat the foliage. Nonnative Note: Do not confuse native skunk cabbage with Asian skunk cabbage (Lysichiton camtschatcense). Note: See John Josselyn note in the appendix.

Ornamental Attributes: Showy large, long-blooming pink, lavender, or rose-purple upward-facing, saucer-shaped flowers April to July. Or, as Keeler writes, “In purple gauze dressed.”58 Seeds end in a long beak (or cranesbill). Lobed, dissected leaves resemble Canadian anemone and also look good until winter, hiding empty spots left by ephemerals. Cultivation: Sun in moist soil. Shade in dry or medium soil; BICKNELL’S NORTHERN CRANESBILL (G. bicknellii). Note: Endangered in parts of the Midwest; CAROLINA CRANESBILL (G. carolinianum). Ornamental Attributes: The latter two have smaller flowers. Nature Note: Geranium nectar and pollen attract small butterflies, skippers, and interesting and beneficial flies. “In the meantime the petals continue their honey call to the bees and the pistil awakens. . . . The life of the flower is usually two or three days; the first day the insects get pollen, which they carry to older blossoms; the second day, seeking nectar, they bring to the receptive stigmas the pollen they have brushed from a younger flower.” A blossom “awaits the insect guests as long as it can.”59 Geraniums host their own moth, the geranium budworm (tobacco budworm) moth (Heliothis virescens), as well as the white-marked tussock moth (Emerocampa leucostigma). The flowers eject and thus scatter their seeds. Chipmunks (p. 14) eat and also spread the seeds.
