Acanthus mollis Acanthus mollis
(Bear's breeches)
(5 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Acanthus mollis is prized for its bold clumps of shiny green leaves topped with striking, 3-foot-tall spires of white flowers which are clasped by showy purple bracts. This is a great plant for an eye-catching structural element in a part-shade border.

(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

Actaea pachypoda Actaea pachypoda

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

This 3-foot-tall and 2-foot-wide clumping perennial displays spiky racemes of white flowers in late spring and early summer followed by bright white berries with dark tips on bright red stalks. The berries are exceptionally showy and especially effective in shady woodland beds.

Actaea racemosa Actaea racemosa

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

Actaea racemosa is a native woodland perennial with white, somewhat fuzzy flowers in midsummer that wave above astilbe-like, deeply cut foliage. The flowers can be unpleasantly scented, thus the name "bugbane." Formerly in the genus Cimicifuga, this plant is great for use in a woodland garden or moist border.

Actaea rubra Actaea rubra

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

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

Compact, easy care and drought tolerant, Blue Storm is one of the Storm™ series of agapanthus that produce more flower stems than any other agapanthus.   In fact, Blue Storm flowers on average 10 weeks per season (up to two to three weeks longer than most other varieties). -Anthony Tesselaar Plants

Ajuga reptans 'Black Scallop' Ajuga reptans 'Black Scallop'
('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

Alstroemeria 'Casablanca' Alstroemeria 'Casablanca'
(Peruvian lily)
(1 user review)
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.

(Joseph's coat, Parrot leaf)

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.

Amsonia hubrichtii Amsonia hubrichtii

Arkansas blue star's delicate, willow-like foliage is topped with pale blue star-shaped flowers in spring. The light green foliage looks good all summer, turns a beautiful golden-yellow in fall, and can stand through most of the winter, adding interest especially when mixed with grasses and other attractive seedheads. It grows to almost 3 feet tall and wide.

Amsonia montana 'Short Stack’ Amsonia montana 'Short Stack’

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

Chalk up another great plant introduction from the folks at Plant Delights Nursery in Raleigh, North Carolina. This dwarf blue star grows to only about half the size of the species, making it well suited for gardens with limited space. It performs best in full to partial sun and is appreciative of moist, well-drained soil. The sky blue flowers appear in early spring above the clean, dark green foliage. Try planting 'Short Stack' in a mess and along bed edges for a winning display.

Amsonia tabernaemontana Amsonia tabernaemontana

In addition to willow blue-star’s small but charming clusters of blue flowers in late spring, it has upright, willow-like leaves that turn clear yellow in fall.
