Rheum

Ornamental Rhubarb

Kin to the edible Rhubarb, these ornamental perennials spawn large brawny leafage and tall intriguing floral spires. Rheum can be utilized as a specimen in the mixed border, the landscape or skirting the water’s edge. They require deep, rich soil and appreciate mulching in the summer to keep their roots cool, as they detest extreme heat.

Lustrous, crinkled and richly red when they first unfurl in the spring, large spade-shaped leaves make a bold statement all season long. The grandiose foliage matures to a handsome deep green on top and grows upright, flaunting prominent veins and opulent burgundy undersides, while starry pale pink blooms on tall flower spikes add a dainty touch.

Blooms June – July.

Size: 4' 0" – 5' 0" high x 3' 0" – 5' 0" wide.

Hardy to zone 5.

Headlining a tall wondrous tower clothed in overlapping hand-sized creamy yellow bracts that veil its insignificant flowers and seeds, this magnificent perennial hails from the high altitude, lush marshy meadows and stream sides of Tibet and western China. Deep roots sprout a lustrous, low basal rosette defined by distinctive white-veined lance-shaped leaves. The long lasting scalelike bracts become streaked with burgundy, while autumn brings fiery claret and orange to the foliage.

A seldom-offered rarity, Alexander’s Rhubarb delivers extraordinary architectural panache to a sunny, yet cool, rich damp location.

Blooms May – July.

Size: 3' 0" high x 18" wide.

Hardy to zone 5.

One of the most pleasing of the tall ornamental rhubarbs, this prehistoric-looking specimen has colossal divided leaves that first emerge in reddish bronze tones. Summer colors them with dark green hues on top and purple-infused undersides, while airy maroon panicles surmount towering flower stalks. Later red shades enliven the foliage for a superb fall finale. Stage with another dynamic performer such as Veronicastrum ‘Adoration’.

Blooms June–July.

Size: 6-1/2' high x 5' 0" wide.

Hardy to zone 5.

Current Staff's Favorite Plant

Helianthus 'Sheila's Sunshine', Persicaria 'Summer Dance', and Selinum wallichianum

Helianthus ‘Sheila’s Sunshine - P-0461

The sunflower was once an emblem of the Sun God of the Incas. Our sunflowers tolerate a wide range of garden soils, attract bees, and make great cut flowers. Blooms early August – October.

Persicaria ‘Summer Dance’ - P-1312

With foliage that’s close to lime-green, and spiky floral tails that approach the scarlet spectrum of rosy pink, this slow spreading perennial is sure to please. Happiest in semishade with ample moisture. Blooms August–November.

Selinum wallichianum - P-1406

This refined Himalayan beauty happens to be one of our favorite perennial umbellifers. With untold elegance, infinitely divided leaves craft a delicate, lacelike transparency. The compact yet airy green canopy is framed by distinctive, purple-infused branching stems that elevate a charming, late season display of white flattened umbels.

Subduing the riotous array of summertime blooms, it seldom needs staking, and appreciates a well draining moist niche. Blooms June–August.
