Prairie Mallow

Sidalcea

Prairie Mallow

Indigenous to western and central North America, these easily grown Mallow family members are adored for their 5-petaled Hollyhock-like blooms that embellish terminal racemes above a basal clump of attractive toothed greenery. Well-drained sites, cool summers, shelter from strong winds and a fall cutback ensure their prosperity, while hot humid weather makes them sulk.

Coveted by butterflies, hummingbirds and floral designers, the dignified, tall upright spikes are generously garnished with glowing deep rose-colored blooms sporting a satin sheen. Large, free-flowing 5-petalled mallow-style blossoms stage a late-season swan song if Prairie Mallow’s compact bushy clump is cut back after the initial posies have faded. Clothed in rounded and lobed, glossy midgreen foliage, this stylish robust U.S. native can be added to meadow-like plantings or perennial borders, where it looks spectacular en masse, appreciates a hard yearly pruning, braves gophers plus most pests, but abhors hot humid summers.

Blooms July–September

Size: 2' 0" – 2-1/2' high x 20" – 2-1/2' wide.

Zone 4b/5.
