Althaea cannabina

The handsome jagged leaves of hemp-leaved mallow will have your THC-loving friends wanting a hit, but sadly for them the foliage is of purely ornamental value.  And this rarely offered perennial is indeed highly ornamental, especially in summer when decked with high-held floating sprays of delicate pink flowers that shimmer in the breeze.

Full to part sun; moist to average soil; 70"x30"; summer to fall; Zone 4

Propagated from seed; deep 3.5-inch pots
