Are hollyhocks annual, biennial, or perennial?
Hollyhocks (Alcea rosea) are biennials or short-lived perennials. Plants usually grow leaves the first year and flower the second, then reseed themselves.
When and how do I plant hollyhock seeds?
Sow directly in late spring or early summer, or start indoors, barely covering the seeds since they need a little light. Seedlings appear in about 10 to 14 days.
How much sun and space do hollyhocks need?
Grow them in full sun in rich, well-drained soil, and space plants about 18 to 24 inches apart. A sheltered spot helps support the tall spikes.
How tall do hollyhocks get, and do they need support?
They can reach several feet, so stake the spikes in windy gardens or plant them against a fence or wall for support.
Will hollyhocks come back each year?
Often, yes. Because they reseed freely, a patch tends to renew itself, and sowing a fresh batch each year keeps the blooms coming without a gap.
Do hollyhocks attract pollinators?
Yes. The big, open flowers are a magnet for bees, butterflies, and hummingbirds all summer.
