Landscapes change over the years. As plants grow, the overall look evolves from sparse to lush. Trees cast cool shade where the sun used to shine. Shrubs and hedges grow tall and dense enough to provide privacy. Perennials and ground covers spread to form colorful patches of foliage and flowers. Meanwhile, paths, arbors, fences, and other structures gain the comfortable patina of age.

Constant change over the years—sometimes rapid and dramatic, sometimes slow and subtle—is one of the joys of landscaping. It is also one of the challenges. Anticipating how fast plants will grow and how big they will eventually get is difficult, even for professional designers, and was a major concern in formulating the designs for this book.

To illustrate the kinds of changes to expect in a planting, these pages show one of the designs at three different “ages.” Even though a new planting may look sparse at first, it will soon fill in. And because of careful spacing, the planting will look as good in 10 to 15 years as it does after 3 to 5. It will, of course, look different, but that’s part of the fun.

At Planting—Here’s how the deck planting (page) might appear in late spring immediately after planting. The rose and clematis haven’t begun to climb the new lattice trellis. The viburnum and lilac, usually sold in 2- to 5-gal. cans, start blooming as young plants and may have flowers when you buy them, but there will be enough space that you may want to plant some short annuals around them for the first few growing seasons. You can put short annuals between the new little junipers, too. The switchgrass and perennials, transplanted from quart- or gallon-size containers, are just low tufts of foliage now, but they grow fast enough to produce a few flowers the first summer.

Three to Five Years—As shown here in midsummer, the rose and clematis now reach most of the way up the supports. Although they aren’t mature yet, the lilac, viburnum, and junipers look nice and bushy, and they’re big enough that you don’t need to fill around them with annuals. So far, the vines and shrubs have needed only minimal pruning. Most grasses and perennials reach full size about three to five years after planting; after that, they need to be divided and replanted in freshly amended soil to keep them healthy and vigorous.

Ten to Fifteen Years—Shown again in summer, the rose and clematis now cover their supports, and the lilac and viburnum are as tall as they’ll get. To maintain all of these plants, you’ll need to start pruning out some of the older stems every year in early spring. The junipers have spread sideways to form a solid mass; prune them as needed along the edge of the lawn and pathways. When the junipers crowd them out, move the daylilies to another part of your property, or move them to the front of the bed to replace the other perennials, as shown here.
