Rheum

Ornamental Rhubarb

Rheums require deep, rich soil and appreciate mulching in the summer to keep their roots cool, as they detest extreme heat.

Rheum ‘Ace of Hearts’    

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'–5' high x 3'–5' wide; hardy to zone 5.

AVAILABLE SPRING 2012

Rheum alexandrae    

Alexander’s Rhubarb

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' high x 18" wide; hardy to zone 5.

Rheum palmatum var. tanguticum ‘Rote Auslese’    

Rote Auslese means “Red Selection”.

One of the most pleasing of the tall ornamental rhubarbs, this prehistoric-looking specimen has colossal, divided leaves, reddish bronze at first, becoming dark green with purple undersides, and eventually quite red in the fall. Airy maroon panicles are produced atop the towering flower stems.

For a bold vignette, stage with other dynamic performers such as Veronicastrum ‘Erica’, and Hemerocallis middendorffii.

Blooms June–July.

Size: 6-1/2' high x 5' wide; hardy to zone 5.
