no image available Saccharum arundinaceum
(Plume grass, Hardy sugar cane)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

In late summer, this large, clump-forming species bears huge plumes of delicate pink flower clusters, which eventually fade to silver.

Salvia canariensis Salvia canariensis
(Canary Island sage)
Be the first to rate this plant
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This short-lived, tender perennial shrub native to the Canary Islands off the African coast sends up 6-foot white-furred stems cloaked with long, felted, arrow-shaped leaves and topped, summer to frost, with plumes of purplish violet flowers clasped by red-tipped calyxes. It grows up to 4 feet wide.

Sambucus nigra 'Gerda' Sambucus nigra 'Gerda'
(Black Beauty™ elderberry)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Valued for its flowers, foliage, and fruit, Black Beauty™ elderberry is a deciduous shrub that requires regular watering during its first few yearsbut will become more drought tolerant as it becomes established. Areas with moist soil are ideal. Black Beauty™ will grow 8 feet tall if left unpruned, but fairly severe pruning in the first year will keep the plant from looking leggy. Pruning will sacrifice the large pink flowers, but the plant will be much sturdier and have a better habit if you do. The flowers, which bloom in June, are large and have a lemony scent. The foliage is dark and finely cut. Elderberries are edible and can be used to make juice or jelly, if the birds don't get there first. -Teresa Smith, Regional Picks: Northeast, Fine Gardening issue #120

Sambucus nigra 'Madonna' Sambucus nigra 'Madonna'
(Black elder, European elder, Elderberry)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This choice specimen livens up the garden all season long with its stunning leaves of green splashed with gold. It bears flattened, creamy white flowers that mature into glossy black fruit. It grows more slowly than most elderberries. It makes an attractive specimen.

Sambucus racemosa ‘Sutherland Gold’ Sambucus racemosa ‘Sutherland Gold’
(European red elder, Golden elderberry)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

This choice specimen has a graceful habit with finely divided golden foliage that emerges as bronze. It is less susceptible to sun scorch than the other gold varieties. It bears creamy white flowers that mature into red fruits. 

Silphium laciniatum Silphium laciniatum
(Compass plant, Pilot plant, Polar plant)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

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.

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

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.

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

If you like plants that stay in tidy, little assigned corners, this is not the plant for you. But if you have a large space to fill and love plants with attitude, this is your baby. False spireas form large masses of arching branches that are covered with green pinnate leaves. Billowy white sprays of flowers appear in mid- to late summer. Mature plants spread where you let them. There is a wide range of closely related species and selections, but there’s not much difference between them.

Sporobolus wrightii Sporobolus wrightii
(Wright's dropseed)
(1 user review)
Hardiness Zones: 1 2 3 4 5 6 7 8 9 10 11

Largely untried in the northern states, Wright's dropseed is a great new grass that is becoming a substitute in southern gardens for unwieldy pampas grass (Cortaderia selloana). Heat and drought tolerant, its gray-green foliage sports airy clouds of flowers atop tall stems in summer. This grass is good as a single specimen or in a group as a showy backdrop.

Stipa gigantea Stipa gigantea
(Giant feather grass, Golden oats)
(1 user review)

This semi-evergreen species makes a stately, stand-alone specimen with narrow, arching foliage and shimmering gold panicles that reach 8 feet tall. The flowers open in June as silvery-purple and mature to shades of wheat.

(Chenault coralberry, Snowberry)

Chenault coralberry is an undemand­ing workhorse. This 2-foot-tall shrub spreads about 10 feet without causing any trouble. It does an excellent job of covering ground and smothering weeds while elim­inating erosion. In late summer, small pink flowers appear and are followed by rosy red fruit.

This hauntingly beautiful specimen has blue-green foliage along matte, purple-green, willowy stems. At 5 or more feet in height, it has a dramatic yet delicate garden presence. Its sprays of nodding lilac flowers have pale yellow stamens. Plant at the back of a border; it may require staking.

This tender perennial climber is evergreen in Zones 10 and warmer. Cheerful, 1.5-inch flowers in shades of orange and yellow cover this fast-growing vine. The blossoms have a simple form: 5 petals surrounding a brownish purple center. Where grown as an annual, plants can reach 8 feet; when grown as a perennial, 20 feet.
