Rheum (Ornamental Rhubarb)
at Digging Dog
Including Rheum ‘Ace of Hearts’, Rheum alexandrae, and Rheum palmatum var. tanguticum
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.
Rheum ‘Ace of Hearts’ (P-1584)
Add to Cart
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.
Rheum alexandrae (P-1669)
Add to Cart
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’.
Size: 6-1/2' high x 5' 0" wide; hardy to zone 5.
Rheum palmatum var. tanguticum (P-1629)

Bring sparkling beauty to your August plantings
Perhaps you’re looking for some soothing floral or foliar accents on a hot summer day! We’ve found that snowy white, clear pink, pale yellow and deep blue blooms coupled with silver, bluish green or emerald-toned leaves become refreshing counterpoints to warmer-hued flowers. They offer a place where your eye can rest, much like cleansing your palette when tasting wine. These shades meld the spicy-colored flowers of many Achillea, Crocosmia, Dahlia, Geum, Helenium, Kniphofia, Rudbeckia and Salvia.
Our next guided Saturday Strolls is August 19th., followed by September 16th & October 7th. We hope you’ll come visit us this summer. Digging Dog's Early August 2017 Newsletter Link
