Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

With their white margins and mottling, the jagged leaves of 'Tasmanian Angel' are a real showshopper, and in late summer, 3-foot-tall, pink-and-cream flower stalks heighten the effect. The variegation may be less pronounced as the leaves age, but the plant still draws the eye. Use it as a multiseason container specimen or as a bedding plant. -Allan Armitage, Plants to know and grow, Fine Gardening issue #119

If your shade garden needs a focal point, consider this small, rounded Japanese maple, with its lime-to-chartreuse-tinged golden leaves. In fall, its leaves turn orange and red, just like those of a sugar maple. This variety, like other small Japanese maples, needs shade and protection from sun and drying winds to keep the foliage from curling and turning brown at the edges. -Michael Ruggiero, Regional Picks: Mid-Atlantic, Fine Gardening issue #127

Black foliage and spiky blue flowers (which appear in early summer) make a dramatic contrast. 'Black Scallop' thrives in full sun, which intensifies the black color. In full sun, the plant produces numerous runners, which should be thinned to prevent crown rot. In large plantings, you can run a rotary mower with a bagger attachment over the patch to control crowding and keep the foliage fresh. In mixed container plantings, the spilling habit of the plant makes it a standout choice. -Ron Smith, Regional Picks: Upper Plains, Fine Gardening issue #120

Albizia julibrissin Albizia julibrissin

(2 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

A large shrub or small tree, Albizia julibrissin is native to Iran to Japan. It is a fast-growing plant whose seedlings can become invasive. It can be seen growing in the wild in the southeastern U.S. and California in waste places, fields, and along roads.

However, its bipinnate, ferny leaves and fluffy pink flowerheads that cover the tree in summer make it a garden-worthy plant, as do the fragrance emitted by the flowers, which attract bees. Seed pods that resemble flat beans follow the flowers and persist into winter. Still, care should be used so that seeds from garden plants can't escape into the wild.

'Casablanca' Peruvian lily is the closest to white that this genus has gotten as of yet. Inside its amaryllis-shaped white flowers, reddish dashes on a yellow wash and a pale pink throat add interest. 'Casablanca' is also taller than most other Alstroemerias. They make great cut flowers and are frequently used by florists; they also add a tropical feel to beds and borders. Roots are very brittle and care should be taken when planting.

Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

A. ficoidea ‘Red Threads’ is a slender-leaved perennial selection that doesn't wander, forming a textured carpet in shades of deep burgundy. A single plant makes a mound about 8 inches tall and 14 inches wide. It blooms on and off all year, but you may never notice. The small, pale flower buttons are held in the leaf axils, where they are nearly indistinguishable from the foliage unless you're paying close attention. Use 'Red Threads' at the base of taller plants in the border to provide vibrant color echoes or contrasts. Grow as a warm-season annual in cooler climates, mass the plants in beds, or use in a formal knot garden as the Victorians did.

This perennial vine sends out abundant pale purple to lavender flowers beginning in late October. It grows to 4 to 5 feet tall, and frost does not seem to impede the blooms. It can attract bees and butterflies well into November.

To get the best flower display, give climbing aster as much sun as possible. It should also have something to lean on, like a fence, a trellis, or an ornamental shrub. Don't prune it over the winter, no matter how dead it may look. It’s better to wait to tidy up things after the new growth appears in spring.

There are many species and varie­­ties of wild ginger, but this vigorous, fast-growing, and beau­tiful species tops my list. Elongated, heart-shaped, dark green leaves look and feel as if they were made out of Naugahyde and splashed with metallic paint. The foliage shimmers when hit by a beam of light. It is evergreen to 10°F but will quickly reappear in the spring if it freezes. If you want to see the unique, 2-inch-wide, dark purple flowers, get on your hands and knees and look at the base of the plants. Though not particularly showy, they are interestingly attractive.
Plants spread quickly by underground rhizomes, forming a thick mat of foliage that crowds out weeds. I recommend spacing them 10 to 12 inches apart and letting them fill in over the next few years. Plants are not picky about soil pH or type, but they do best in well-drained areas. -Jimmy Turner, Plants for dry shade, Fine Gardening issue #133

Tatarian aster is an impressive, stately perennial with a flowering height of 3 to 6 feet. It can look you in the eye yet require no staking. More important, this aster flowers longer than any other garden aster, beginning in late September and early October and continuing into November. The 1-inch-wide, light lavender flowers are a magnet for local and migrating monarch butterflies. This plant tolerates many soil types, can form large colonies in a few years, and is easily divided.

In late spring, lavender-pink flowers rise above this plant’s lacy, fernlike foliage, which forms an airy network beneath. The blooms appear a bit later than typical for other astilbes, and they extend later into summer. ‘Maggie Daley’ is moderately drought tolerant once established. Pair it with Japanese painted fern (Athyrium niponicum var. pictum, Zones 5–8) for a beautiful combination.

This is the most drought-tolerant bergenia I’ve found and the only one that does well in Texas heat. The large, hairy, critter-resistant leaves do not resemble other members of this genus; they look more like hairy plates or giant African violet leaves—hence, it’s common name. Mature plants will send up 10-inch-long stems of white to pale pink flowers from spring to early summer, but the real reason to grow this plant is its remarkable foliage.
In cooler regions, hairy bergenia grows not only in the shade but also in full sun. It isn’t particular about soil type or pH. Divide plants every three to five years to keep them vigorous. -Jimmy Turner, Perennials for dry shade, Fine Gardening issue #133

The toothed leaves are bright green. This low-maintenance, hardy perennial retains its evergreen foliage through winter.

By late fall, as the older crowns die out, new rosettes of leaves appear at the ends of underground rhizomes, giving the illusion that the plants have moved. This is not a desirable trait in formal beds, but it's an asset in naturalized plantings.

I have a penchant for vigorous, spreading plants: For the price of one plant I can get tons more for free. Plus, plants that spread out are naturals for dry shade; the expanded network of root systems feeds the whole plant, helping it get the water it needs. ‘Pink Octopus’ quickly forms wide mats of tall, deeply cut, light green foliage. Throughout spring, octopus-shaped, candy pink flowers float in a mass over the foliage, sporadically appearing throughout summer. I use this plant as the horticultural equivalent of a slipcover to coat large areas of shade quickly, especially because it can handle the extremes of my Texas climate.

Because it is a relative of the immensely popular burning bush (E. alatus), it isn't surprising that eastern wahoo has great fall color. This North American native grows as a small tree in the southern part of its range and as a large shrub on the Plains. The bright red of its fall foliage is amplified and extended by abundant clusters of scarlet fruits that persist after the leaves have fallen, providing color even into midwinter. Eastern wahoo is effective as an accent plant or when massed wherever a bold, surprising splash of color is desired.

If you dwarfed flowering raspberry (Rubus odoratus, Zones 3–7) and sent it to finishing school, Japanese wood poppy would be the result. Birders will note that Glaucidium is also the name of a genus of owls, and gardeners may, ahem, hoot and flap when they see Japanese wood poppy in full bloom. This debutant may need a year or two to refine before flowering, but when it does, the coming-out party is a show of violet sepals. (White varie­ties are also available.) Naturally, it will wilt in the heat and will require shade and regular water. -Justin Nichols, #Fine Gardening 147 (October 2012), page 70

Honey locust grows in the wild from Pennsylvania to Iowa and south to Georgia and Texas. In the landscape, this large, spreading, deciduous tree is valuable for its elegant form and pinnate, ferny leaves that cast a dappled shade. Flowers are generally inconspicuous, but are followed by unusual large seed pods. Fall color can be a nice yellow, but leaves sometimes fall without noticeably changing colors. The species has a thorny trunk and shoots, but thornless cultivars are available.

‘HGC Pink Frost’ is part of a new series of hellebores that, for the Midwest, bloom very early, some as early as January; this cultivar blooms a bit later, usually in March. The bud count is high, with buds coming out in February all along the plant stem. They start out a deep burgundy but open to soft pink, then age to earthy rose shades. Flowers rise above the foliage, so they are never hidden, and they face outward, creating maximum interest. -Irvin Etienne, Fine Gardening issue 147, page 72

Sapphire jewelweed grows remarkably fast, reaching almost 2 feet tall and wide. It shines in a woodland garden.

The showy purple spikes of purple loosestrife are attractive in the garden and along roadsides, but the plant's rampant spread has greatly reduced the ecological value of marshes by displacing native wetland vegetation such as cattails (Typha spp.) that wildlife uses as food or shelter. One mature plant can produce over 2 million seeds a year that are easily transported by the wind or water into wetlands. The seeds easily germinate, and no natural predator holds this plant in check. Even cultivars reported to be sterile can produce highly fertile seed if grown with other cultivars or wild loosestrife.

“Soft caress,” indeed! You’ll barely recognize this shade dweller as an Oregon grape when it sends up its long slender foliage without a single thorn. Its spikes of fragrant, lemon yellow flowers bloom from fall through winter, and will add a jolt to any shady bed. But the large clusters of silver-blue berries that follow the blooms are what I look forward to most. For the best results, give this drought-tolerant perennial afternoon shade, well-draining soil, and plenty of water the first year. -Leslie Finical Halleck, Fine Gardening # 147 (October 2012), page 74
