Perennials, Flowers

SPHAERALCEA

Grown for their attractive downy leaves and bright flowers shaped like miniature hollyhocks (Alcea rosea), these upright to trailing plants have a persistent woody base with softer stems above. Colorful accent plants for hot, dry locations.

Need well-drained soil. Any more than a little water causes weedy growth and rust. Cut old stems almost to the ground before spring growth begins.

Sphaeralcea munroana

Native to intermountain West and Rocky Mountain foothills. Grows to 3 ft. tall and 1 1/2–2 ft. wide, with upright stems and rounded, slightly lobed gray-green leaves. Bears many wands of inch-wide salmon to reddish orange flowers from midsummer to early fall. Plants sold in California under this name may be the Argentine native S. philippiana, which grows to 1 1/2 ft. tall and 4–5 ft. wide and has leaves that are more deeply cut than those of S. munroana.
