Pachyphragma macrophyllum Pachyphragma macrophyllum
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Rounded, ruffled leaves form a solid, weed-free, evergreen ground cover. In the spring, elongating shoots open to rounded heads of small four-petaled white flowers. Plants remain in bloom for nearly a month, opening new flowers from expanding terminal clusters as well as from numerous side shoots. Mature plants stand 12 to 18 inches high when in flower, and spread in time to form clumps 2 to 3 feet wide.

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

This clump-forming, semi-evergreen perennial has long prostrate stems and pewter-green foliage. Fragrant, bottlebrush-like white flowers are borne on 2- to 4-inch-long spikes in spring, as the foliage appears.

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

This stunning herbaceous woodland peony has upright red-mottled stems and dark green leaves that are elliptic or lance-shaped with rough margins. It bears usually solitary, single creamy white to pale pink blossoms that are cup-shaped and elegant. The blooms measure 3 to 4 inches across and have pale yellow stamens. Like all peonies, the flowers are with us for too short a time. They are followed by beautiful seedpods.

(Japanese forest peony)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This plant is a beautiful addition to the garden from early spring until autumn. Red shoots with a crystalline dusting emerge in early April, followed by 5-inch-long, egg-shaped leaves that mature to a dark, reddish green. Each 18-inch stem bears a 2-inch-wide, chalice-like, single pure-white flower with yellow anthers and purple filaments. Mature seedpods open to reveal metallic-blue pea-sized fertile seeds and holly-berry red unfertilized seeds.

Paeonia suffruticosa Paeonia suffruticosa
(Tree peony)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This upright, sparsely branched, woody shrub reaches 4 to 10 feet tall. It's easy to grow but slow-growing. It displays dark green leaves that are blue-green beneath, and large, silken blossoms 6 to 12 inches across in late spring and early summer. The plants maintain a graceful branching structure throughout the winter.

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

Iceland poppy is a short-lived perennial usually grown as a cool-weather annual, or biennial.

Papaver orientale 'Flamenco Dancer' Papaver orientale 'Flamenco Dancer'
(Poppy)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

The 4- to 6-inch-wide blooms of 'Flamenco Dancer' poppy stand out in late spring and early summer with their true red color and fanciful fringes. It is a sport of the popular 'Turkenlouis'. After the flowers fade, this perennial will go dormant, so plant it near neighbors that will fill the vacancy.

Parrotia persica Parrotia persica
(Persian parrotia tree, Persian ironweed)
(3 user reviews)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Parrotia persica has one of the most beautiful foliage displays, in addition to year-round eye appeal and ease of maintenance. Reddish-purple when unfolding in spring, the leaves are a lustrous dark green in summer, and yellow to orange or scarlet in fall. Leaves hold their color for a long period. Older branches and trunks develop an exfoliating gray, green, white, and brown color that is a welcome asset in the winter garden. It grows successfully in Zones 4 to 8, tolerates sun and partial shade, and is easy to transplant. Often, vegetatively propogated forms offer more reliable fall color.

This deciduous tree has thick shoots and large, lobed, bright green leaves. Fragrant pinkish lilac flowers appear in late spring with the foliage. When grown as a perennial, its robust shoots become sturdy stems 2 inches in diameter, with mammoth leaves as much as 2 feet across. Paulownia tomentosa can grow to 12 feet tall in a single season.

Pelargonium 'Crystal Palace Gem' Pelargonium 'Crystal Palace Gem'
Be the first to rate this plant

'Crystal Palace Gem' was first introduced in 1869 and has been a star in the garden ever since. It was named for Joseph Paxton's elaborate glass house designed in 1851 for London's Great Exhibition in Hyde Park. Like its namesake, the plant is showy, with its round chartreuse leaves with a midgreen center and its salmon-red flowers. 'Crystal Palace Gem' looks good from spring until frost. -Marty Wingate, Plants to know and grow, Fine Gardening issue #120

Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This exemplary species has felted, gray, crinkled leaves. Over a long period, it exhibits sprays of butterfly-shaped, rich wine-red flowers, which contrast dramatically with the foliage. Its small stature makes it a perfect candidate for a container or a walkway edge. It has been used medicinally for the treatment of various infections, including bronchitis. It is a native of Africa.

Pelargonium tomentosum Pelargonium tomentosum
(Mint-scented geranium, Peppermint geranium)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

The velvety leaves of this choice species are pale green with long, silky hairs. The angora-like feel of the foliage is matched by its heavenly aroma of fresh mint. It bears clusters of dainty white blossoms in spring, but remains an exceptional foliage plant throughout the year.

Be the first to rate this plant

Penstemon cobaea has shiny dark green leaves and purple, pink, or white flowers on spike-like panicles in mid-spring. It grows to 2.5 feet tall. The flowers are larger than most other penstemons. Dew flower is native to the Lower Plains and the southwestern U.S.

Penstemon digitalis 'Husker Red' Penstemon digitalis 'Husker Red'
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

'Husker Red' is one of the few penstemons that does well in wet winters and hot, humid summers. Ruby-toned leaves appear in spring, followed in late spring and early summer by 3-foot-high stems adorned by panicles of white blooms.  The flowers attract bees, hummingbirds, and butterflies, but the plants are not magnets for deer or rabbits. In autumn and winter, songbirds feast on the seed. For a stunning display, plant 'Husker Red' in groups. -Chris Kelley, Regional Picks: Midwest, Fine Gardening issue #120

Tubular lavender-pink flowers with paler pink lobes are borne in late spring to early summer. The foliage is evergreen.

Penstemon nitidus Penstemon nitidus
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This penstemon produces azure flowers—the color of a New Mexico summer sky. Blooms emerge in late April and may get covered with a late snow, but that doesn’t seem to bother them. Also boasting beautiful gray-blue foliage, this plant grows 6 to 10 inches high.

Penstemon palmeri Penstemon palmeri
(Palmer's penstemon)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

A native of the Southwest, Palmer's penstemon sports sharp, prickly, gray leaves and thrives in the harsh conditions. Snapdragon-like pale pink flowers boom in late spring or early summer, and their sweet-honey scent attracts bumblebees. Toothed, sage green leaves skirt the upright stems for the rest of the gardening season.This perennial wildflower is one of the largest penstemons. It looks good in the back of a border or as a focal point, perhaps near a path where its fragrance can be enjoyed or in an informal grouping with other native penstemons and grasses, or with other plantss that have similar maintenance and water requirements. -Katie Nicolich, Plants to know and grow, Fine Gardening issue #120
