We cultivate in our gardens plants of all kinds, which give us great pleasure on account of their lovely blossoms or their agreeable odors. They are no longer luxuries, but have become necessities of life; and never have they become so extensively grown and widely appreciated as now. There are plants suited for sunny and shaded aspects and for various positions, from the mossy dell to high and dry situations in the country; from the area to the housetop in the town. Only knowledge is wanted for making the best selections for different purposes and sites, with information on culture for the uninitiated to achieve satisfactory results.

Plants and flowers grown in gardens are embraced in three groups: 1. Annuals, 2. Biennials, and 3. Perennials, the last-named being divided into two sections: (a) herbaceous, with soft or succulent stems that die in the winter; and (b) shrubby perennials with woody stems that survive the winter.

Annuals are those flowers which are born, grow, flower, ripen seeds, and die within a year. They never push growths a second season after flowering, because the roots die as well as the tops and branches. The common scarlet Poppy is a typical example.

Biennials are those plants which are raised from seeds in the spring or early summer and require the whole season to make their growth preparatory to flowering the next year, dying after ripening seeds.

Perennials differ from the above in living more than two years. All plants, such as hardy border flowers, that die down and spring up again from the root-stock year after year are perennials—herbaceous. Roses and other flowering shrubs are also perennials, but not herbaceous. Orchids. One of the best examples of herbaceous perennials is that of the Orchids, the most popular of which are the Odontoglossums and the Cattleyas.

Florist’s Flowers. This term has been applied to a number of plants which under cultivation and by selection or hybridization have produced from seed varieties of improved form, habit or color. The plants included under this title are constantly being added to, and great impetus given to the cultivation of hardy flowers and plants in recent years. The following are representative of this class:

Begonia. Named in honor of M. Begon, a French patron of botany. All the species of Begonia are interesting and beautiful winter ornaments of the hot-house or green-house, of the simplest culture in any rich soil if allowed an abundant supply of water. There are several tuberous-rooted species and varieties. They have large, showy flowers, and succeed well in a moist, shady border. The tubers should be kept warm and dry during the winter. They are readily propagated by cuttings, seeds, or division of tubers.

Carnation (Dianthus caryophyllus) is an almost hardy herbaceous perennial plant, a native of southern Europe. The Greeks and Romans used it for making chaplets whence it was called “coronation.” It is a favorite exhibition flower, of many varieties, forms and colors; but the red, white, pink and yellow predominate. Carnations are among the plants which can be grown in the atmosphere of cities, but they are intolerant of shade. Propagation is usually effected by the process of layering, but cutting, seeds, and divisions are also employed.

Cattleya. What the rose and carnation are among garden plants, the Cattleya is among Orchids, preëminently beautiful. Not a species but possesses claims of the strongest nature on the culturist’s attention, either for its delicate loveliness or the rich and vivid coloring of its large and handsome flowers. They are natives of the temperate parts of South America, and in cultivation are found to succeed in a lower temperature than is necessary for the majority of plants of the same order. The plants grow vigorously, and consequently flower in perfection. The colors of the flowers run through all the shades of white, rose, rosy-lilac, crimson and carmine, nor is even yellow absent.

Dahlia. This, through constant improvement, has become one of the indispensable flowers. It derived its name from the Swedish botanist Dahl. Dahlias are known as show, fancy, pompon, single and cactus. They vary from the single type, not unlike a daisy, with broad rays, to the tiny, tightly-quilled, formal “pompon,” and to the “cactus-flowered,” resembling a chrysanthemum; and their lines are equally varied. Yellow, lilac, white and the deepest maroon, are found in innumerable combinations. It is necessary to lift the roots in late autumn, and, having ripened them in a shed, to store them for the winter in a cool, dry place, where the temperature will not fall below thirty-two degrees Fahrenheit. In the spring, the separate tubers may be planted in deep, rich soil; or the roots may be placed in February in a hot-bed, and when the young shoots which form are about three and a half inches long, they may be separated, together with a small piece of the tuber, and potted in small pots, which should be placed in the hot-bed until the young plants are ready to be hardened, preparatory to being planted outdoors.

Geranium. Our native species, called “crane’s bill,” from the beak-like appearance of the fruit, have palmately lobed or cleft leaves. The flowers have unusually bright-colored petals. The plants commonly cultivated in gardens and greenhouses under the name of Geraniums are species of Pelargonium. There are about one hundred and twenty-five species, mostly natives of the Cape of Good Hope, prized on account of the brilliant colors, of the flowers and the shape and markings of the leaves.

The most popular method of propagating is by cuttings, which can be rooted in pots or boxes of light soil placed in a greenhouse, or even a cottage window, at any time from spring to autumn, provided the soil is not kept very moist. Good loam is the best potting material, and beyond a little sand it needs no addition. Firm potting is a point to be well observed. Avoid coddling.

Gloxinia is the florists’ name for plants belonging to the genus Sinningia, tropical American plants. They have beautiful, many-colored, funnel-shaped flowers and velvety leaves. Seeds should be sown in February; and if the young plants are carefully potted, they flower the first year. They require the temperature of a warm greenhouse during the summer months; but as the leaves die away in autumn, the roots may be stored in a dry place, merely protected from cold. They like a sandy soil, containing abundance of leaf-mould and heat.

Lily (Lilium) in its many forms is one of the noblest and must beautiful of all bulbous plants. About forty-five species are natives of the north temperate zone, many of which are prized for the size and beauty of the flowers. The White Lily (L. candidum), a native of the Levant, with large white flowers, has long been in cultivation in gardens. The European Orange Lily (L. bulbiferum), with large, orange-colored flowers, is a well-known and very showy ornament in flower gardens. The Tiger Lily (L. tigrinum) has a stout stem two to five feet high with beautiful orange-colored flowers, spotted with purple. It is a native of China but has escaped from cultivation in many parts of the United States.

PROUD COLOR BEAUTIES OF THE LAND OF FLOWERS

1. ANTIRRHINUM. 2. THE ODONTOGLOSSUM. 3. POPPIES. 4. GLOXINIA. 5. CORNFLOWERS. 6. NASTURTIUMS. 7. THE CATTLEYA FOBIA. 8. FOXGLOVE.

Nasturtium, the generic name of a plant of the cruciferæ or mustard family, and the common name of the widely different genus tropæolum. The best known of these is Tropæolum tricolorum, one of the most generally cultivated annuals. It has tuberous roots, and such very weak and slender stems, that it is found necessary always to train them over a wire frame, as they are quite unable to support themselves. The stem climbs six or eight feet; the flowers vary from yellow to orange, scarlet and crimson. The unexpanded flower buds, and the young fruit while still tender, are pickled in vinegar. The dwarf varieties of this form bushy, rounded tufts about a foot high, and are used for bedding; some of them have flowers of exceedingly rich colors.

Odontoglossum. Unquestionably the most popular genus of Orchids. Very many of the species have been introduced into the green-house, and are greatly prized by cultivators for their magnificent flowers, which are remarkable both for their size and the beauty of their colors. Many of the species have pure white flowers, variously mottled; and some have a powerful odor of violets. With but few exceptions, they require to be grown in a moderately cool house. They are propagated by division, and grown like the other varieties of Orchids.

Tulip (Tulipa). A genus of upward of eighty species of hardy bulbous plants. Between forty and fifty species are known, mostly natives of the warmer parts of Asia. The most famous of all florists’ flowers is the garden tulip (T. gesneriana), which is from eighteen inches to two feet high, with a smooth stem, bearing one erect, large flower. The tulip is still most sedulously cultivated in Holland, especially at Haarlem, whence bulbs are largely exported; but attention is almost exclusively devoted to the cheaper varieties, which are used in hundreds of thousands for the purposes of decoration in gardens and rooms throughout winter and spring. Tulips are propagated by offset bulbs, and new varieties are raised from seed. Another species of tulip cultivated in gardens is the sweet-scented tulip, or Van Thol tulip (T. suaveolens), which has yellow or red flowers, inferior to those of the common garden tulip in beauty, but prized for their fragrance, and for appearing more early in the season.
