(Bear's breeches)
(1 user review)
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

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

Unlike other bugbanes, 'Hillside Black Beauty' offers deep purple-black foliage. From late spring to late summer, its dark hue makes a wonderful backdrop for colorful foliage and flowering shade plants. In fall, fragrant, cream-colored flowers appear on tall, wandlike stems. An added plus: this plant is deer resistant. --Michael Ruggiero, Regional Picks: Mid-Atlantic, Fine Gardening issue #127

('Black Scallop' bugleweed)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

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

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

The drumstick allium has egg-shaped flowers in summer that start off green, then bloom and develop to pink and then clover red-purple. These plants are attractive in a bed or border, especially peeking up through other plants, such as roses, so that their nondescript foliage is hidden. Their vertical presence and eye-catching flower shape are valuable additions to the garden, and they naturalize freely.

It also has pale stalks with purplish banding. 'Frydek' is very tolerant of a range of soil pH, heat, humidity, and heavy soil. It can even take about a half day of sunlight.

Alstroemeria 'Casablanca' Alstroemeria 'Casablanca'
(Peruvian lily)

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

'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.

To put it in perspective, ‘Star of the East’ crocosmia is as far removed from the well-known ‘Lucifer’ crocosmia as Lady Gaga is from an Appalachian clogger. ‘Star of East’ is a strong grower without being aggressive, starting the season off with attractive green leaves that are held verti­cally. The foliage remains upright and in good condition well into fall, which isn’t always the case with other cultivars. The flower stems are exceptionally sturdy, too, and they need to be because they bear some of the largest flowers of any crocosmia—nearly 4 inches in diameter.
In late summer, deep orange flower buds emerge like tubes of lipstick from protective bracts. The flowers open widely with a glowing, soft orange face highlighted by a pale center. A surprisingly long bloom period is a bonus, the blossoms perfectly mixing with the other hot colors of late summer and then seamlessly blending into the warm oranges and yellows of autumn.

For a change of pace, 'Zorro' looks fantastic floating stemless in a bowl of water. The ruffled petals accentuate the dark red hue. Staking is a must to prevent the stems from flopping beneath the weight of its huge and heavy blooms. Pinch back the young shoots to promote branching and sturdier stalks. 'Zorro' consistently produces quality tubers for division and, as such, is the perfect cultivar to start (or sustain) a dahlia collection. -Alastair Gunn, Dahlias that deliver, Fine Gardening issue #121

Originating in mountainous woodland and stony habitats from Europe to western Asia, yellow foxglove is tolerant of dry shade but flourishes with moisture. Arising in midsummer from neat clumps of fine-toothed foliage, a mass of soft yellow open bells, speckled brown inside, blooms along one side of a 3-foot-tall stem. Usually described as a perennial, it is more accurate to call it a biennial or short-lived perennial. If the flowering stalk is cut down after blooms have faded, it may rebloom in the fall. When a few flower stalks are left, the plant self-seeds.

Candelilla forms an upright clump of slender, waxy gray-green stems. Inconspicuous leaves appear on new growth but quickly drop with the first dry spell. Tiny flowers of cream and rosy pink periodically hug the upper portion of the stems throughout the warm season, particularly in response to rain. Candelilla is perfect for narrow planting strips because its stems grow straight up in tight bundles.

Daylilies are traditional candidates for the perennial border. They blend perfectly into mixed and shrub borders. Compound color by massing or combine two complementary colors for a dramatic composition. Excellent edging plant for rigid sidewalks, naturalistic flagstone footpaths and for tidy color at the edge of the lawn. Lovely for nesting rough edges of landscape boulders, or for color around rock strewn water features and dry stream beds.

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.

Sweet William catchfly's vivid dark pink flower clusters beautify the garden in late summer. It is a herbaceous perennial most often grown as an annual, as it readily propagates from seed. Native to Europe, it has escaped gardens and naturalized in eastern and central North America, as well as the Pacific Northwest.

This tall, sturdy prairie plant makes an imposing statement in the garden with its large, deeply cut leaves and yellow sunflower-like flowers that face east and bloom in late summer and early fall. The leaves of the compass plant can grow up to 18 inches long and are deeply incised with a shape that looks like something from a painting by Matisse. They align themselves on a north-south axis to conserve moisture by avoiding the midday sun. This plant requires a few years to enlarge and flower, but once its deep roots are anchored, it will live for many years.

A coarse but bold perennial giant for the back of the border with yellow, daisy-like flowers in summer. Cups form where the toothed leaves meet the thick stems; birds are said to drink from the water held in the cups. Tough prairie natives that will self-sow, these plants need lots of sun and lots of room—a single plant can reach 7 or 8 feet tall and 6 feet across.

In early summer, these grass-like perennials produce multiple spikes of small, pale yellow blooms with dark yellow centers and faint purple stripes. The flowers rise above gray-green foliage. Native to open woods, meadows, and prairies of South America, these adaptable wildflowers tolerate a wide range of conditions and naturalize easily. The summer blossoms each open for just one day with the morning sun and close at dusk. Rarely do the blooms open on cloudy days. Plants grow to 3 feet tall and 10 inches wide.

Coleus are tender tropicals that are generally grown as annuals because they are hardy only in Zone 11. The variously shaped leaves of these popular bedding plants typically combine several colors, such as chartreuse, rust red, cream, and purple-black. Some cultivars sport almost all of these colors combined. The darker the red in the leaf, the more sun the plant will tolerate. Coleus blooms in summer, but the blue to white nettle-like flowers are unremarkable and tend to detract visually from the impact of the foliage. -Debra Lee Baldwin, Regional Picks: Southern California, Fine Gardening issue #127
