Thrusting upward from fleshy roots late in the spring, Roscoea’s green stems are sheathed by alternate glossy foliage, while its large lobed flowers possess an otherwordly appeal. An exotic-looking genus that counts Ginger among its kin, these Tibetan and Nepalese natives appreciate a deep planting and a thick layer of mulch for winter protection.
Paying homage to Ginger aficionado William Roscoe, who founded the first Liverpool Botanical Garden in 1803, this Himalayan denizen bears splendid, large orchid-like vibrant purple blooms atop folded green foliage that resembles petite sweet corn leaves. Tuberous, quick-to-clump roots sustain the sturdy, low mounding stalks plus long-blooming hooded flowers. An exotic hardy member of the Ginger family, Roscoea purpurea detests hot humid weather, looks most showy when planted in swaths and lends prismatic floral delicacy to the rockery or a cool moist woodland milieu.
