Hollyhock are perhaps the definitive old-fashioned garden plant. Flowering from late spring through summer, these are the tall stately flowers you looked up to in your grandmother's garden. Best selection for the coldest areas (zones 3 & 4), not for the gulf states.
Although biennial, allow seeds to fall and the clump will persist for many many years. May need staking. Rust (little orange dots on the leaves) can be a problem in high humidity and can be treated with a copper based fungicide.
Our plants are all grown in plantable fiber pots that grow incredibly vigorous plants, eliminate transplant shock, and are 100% biodegradable. They have tremendous advantages over plastic pots.
