Alexander’s Rhubarb

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 alexandrae full sun  partial shade

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)

Sterling Spring blooming shrubs, plus head-turning Perennials.

Here’s the tall and short of it…

Sterling spring blooming shrubs, all dressed in classy green leaves and crisp white flowers. Viburnum plicatum ‘Summer Snowflake’ is the largest of our featured shrubs, fashioning graceful somewhat horizontal branches adorned with snowy lace caps. Cultivated since 1868, well-loved Spiraea x vanhouttei makes a shapely low maintenance addition to sunny mixed borders, while smaller-statured Deutzia gracilis ‘Nikko' offers a galaxy of dainty white blooms perfect for the rockery, nestled along steps or in a container.

Head turning Perennials

Nearly 65” of rain coupled with chilly spring days spawned a remarkable surge of lush foliar growth, plus spectacular long-lasting flowers in our nursery & garden this year. Spring is always such an exciting time as we watch the multitude of leaves, buds and blooms that seemingly unfurl over night plus the numerous new shoots stretching skyward. Dicentra ‘Gold Heart’s delicate golden foliage glows in dappled shady niches, while the dark leaves of Eupatorium ‘Chocolate’, Astrantia ‘Moulin Rouge's exquisite domes, and the richly colored Sedum ‘Jose Aubergine’ promise to turn more than a few heads in your garden. Perhaps you could let Campanula ‘Blue Waterfall’ cascade down your garden steps, or brighten up a sunny bed with Geum ‘Prinses Juliana’. We hope you’ll make room for a few of these shrubs & perennials. Our extensive display borders which surround the nursery are now open through Colombus Day weekend. Our first guided Saturday Stroll is June 24th., followed by July 15th & 29th. We hope you’ll come visit us this summer.
