Wherever you have a house, and trees growing near it, you have a yard that's at least partially in shade. A definite plus when you're seeking refuge during a high-noon summer barbecue. Not so much of an advantage when you're trying to create a beautiful landscape. After all, the aisles of the average garden center are filled with sun-loving perennials—and just a handful of run-of-the-mill groundcovers (think ivy and pachysandra) to cloak shady spots. But, says This Old House landscape contractor Roger Cook, "it's not difficult to find interesting plants for shade. You just have to do your homework and find ones that are suited to your particular low-light conditions."

That means quantifying how much sun your site does get. In general, if it receives three to five hours of morning sun each day, that's considered partial shade; two hours or less each day is full shade. Soil conditions also determine which plants will thrive. If you can mold a fistful of loamy soil into a ball that holds its shape, it's moist, which is just right for most shade-loving plants. If it breaks into powdery clumps, it's dry—typical under trees with extremely dense foliage and tenacious roots—and you'll need to find plants that can tolerate that type of soil.

Though plenty of shade plants bear ornamental flowers, often their real beauty lies in their drama-tic foliage. Leaf colors may range from chartreuse to blue-green to purple. Yellow-gold and silver -foliage can bring the botanical equivalent of sunlight and moonlight to shady planting beds.

Keep in mind, too, that you can turn the deep shade created by trees into partial shade by limbing up or thinning branches, or by removing some specimens altogether. Also, shade beneath deciduous trees isn't the same year-round, so woodland plants and flowering bulbs that bloom in spring are often able to take advantage of more of the sun's rays before limbs have leafed out.

On the following pages are some standout shade plants to try—they might just turn low-light areas into the highlight of your landscape.

TIP

Learn by example. To find out what grows best in your area, visit a botanical garden (visit garden.org for near you). Many have demonstration shade gardens that serve as a teaching tool.

Note: Even within species, hardiness ratings for particular cultivars may vary.

TIP

Try recreating the natural habitat of woodland plants. You can mimic the leaf litter found on the forest floor by enriching your soil with a mix of shredded leaves and compost, then topping it with a thick layer of bark mulch.
