FAQs

Is “Blue Hollyhock” truly blue?

No true sky-blue hollyhocks exist. Expect blue-toned violet to deep purple blooms; shade varies by genetics and conditions.

Is this annual, biennial, or perennial?

Hollyhock is typically biennial or a short-lived perennial that self-seeds, so it often returns year after year.
