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.

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.

Colorful Crocosmias!

Crocosmias pack a punch of late summer color as our gardens transition into autumn. Their clustered tubular flowers populate the ends of gracefully arching spikes, which emerge from handsome sword-like foliage. Ranging from yellow, peach and orange to fiery red, their prismatic shades look exceptional with white flowering perennials such as Phlox ‘David’, Selinum wallichianum and Aster ‘Bridal Veil’, as well as the blue blossoms of Aconitum, Agapanthus ‘Storm Cloud’ or Aster ‘Twilight’. For fun you could create a hot border, blending them with Kniphofia, Helenium, Salvia and even other Crocosmia, plus be sure to include some in your next bouquet. Commonly referred to as Montbretia and hardy to Zone 6, they appreciate, good drainage, adequate water and some shade in scorching summer sun. Please feel free to check out our extensive collection of Crocosmia cultivars in the perennial section of our online catalog.

YES, it’s possible to be in awe of your late August garden….

At this point in the season, some areas in our gardens may appear a tad worn or lackluster. If you haven’t already done so, you may wish to cut back a few tired looking perennials, such as the Nepetas or Geraniums, so you can enjoy a fresh flourish of growth plus more blooms. Adequate moisture and an additional application of compost will also ensure late summer vigor. Incorporating plants that provide a bounty of flowers and alluring leaves in August and September helps buoy our spirits, and hopefully even inspire a little awe as we approach fall. Though the plants featured in this newsletter either promote a bold statement or possess more refined aspects, they equally caught my eye and made me pause to take a closer look. Perhaps they’ll spark a wondrous moment for you as well. All of us Digging Dog plant wranglers wish you Happy Digging!
