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.

Rheum ‘Ace of Hearts’ (P-1584)

Each $13.25

AVAILABLE SPRING 2020

<i>Rheum</i> ‘Ace of Hearts’ <i>Rheum</i> ‘Ace of Hearts’

Lustrous, crinkled and richly red when they first unfurl in the spring, large spade-shaped leaves make a bold imposing 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|#8211;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.

<i>Rheum palmatum</i> var. <i>tanguticum</i>

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. Warm weather brings dark green foliar hues on top and purple-infused undersides plus airy maroon panicles surmounting towering flower stalks. Later red shades enliven the foliage for a superb fall finale. Stage with another dynamic performer like Veronicastrum ‘Adoration’.

Blooms June|ndash;July

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

Hardy to zone 5.

Cercidiphyllum japonicum: A tree brimming with elegance....

An inhabitant of China and Japan, Cercidiphyllum japonicum usually grows as a refined multitrunked tree with a pyramidal to rounded canopy. Cloaking gracefully structured branches, the lovely somewhat heart-shaped deciduous leaves unfurl in bronzy purple tones, and later exhibit medium bluish green hues for summer. The foliar grand finale includes brilliant yellow, apricot, orange or mauve colors plus a sweet strawberry-like scent that wafts some 15 feet or further on sunny, warm fall afternoons. This easy-care tree prefers adequate moisture as well as some protection from hot scorching sun and drying winds.

Autumnal Allure...

One of the greatest joys of gardening is witnessing the changes that occur in our landscapes throughout the year, and many deciduous woody plants pretty much top the list for affording dynamic seasonal transformations, especially in autumn. Most of the trees and shrubs featured in this newsletter are renowned for both their handsome habits and prismatic fall displays. We’ve also included a few of our favorite perennials that lend late season floral or foliar intrigue.

All of us Digging Dog plant wranglers wish you Happy Digging!
