Plant of the Week 08/30/2019

Hollyhock Alcea rosea 'Nigra' Zone 3-8

Blackish-purple flowers cover the tall stalks on this summertime stunner. Large green leaves create a beautiful base for this perennial. Blooms will bring lots of bees due to the heavy pollen. A fast grower that can quickly reach 8' tall and 2' wide.

For best growth plant in full sun, but will tolerate part shade. Cut stalk once done blooming to prevent the seeds from spreading, or allow seeds to drop for lots of hollyhocks the following year. Small hairs on the plant can irritate skin. Prune leaves in late fall to prevent a safe haven for pests.
