Wow! Amazingly striking and a statement flower for any border or garden! This is the blackest single heirloom hollyhock available; listed in an 1827 Toronto Ontario Nursery Catalogue.
- well drained, fertile soil, will tolerate moist soil
- Spacing: 30 cm
- Season: summer to fall.
- Sow indoors 6-8 weeks prior to last frost and transplant out when seedlings are strong enough to handle, or direct sow after last frost. Do not cover seed.
- Note: Hollyhocks need full sun and moist, rich, well-draining soil. The mistake many novice hollyhock growers make is to plant this flower in soil that's too dry. If you are planting seeds, sow them outside about a week before last frost. If you are planting seedlings out, wait about two to three weeks after last frost.
- Hollyhocks do not usually bloom the first year from seed unless it is sown early. They also self-sow and the first year the seedlings will not bloom.
- To force biennial hollyhocks to flower the first year, treat them with gibberellic acid, a flower inducer that takes the place of a cold period. Planting them in fall may also induce hollyhocks to bloom the first year.
- Hollyhock is completely edible – leaves, roots, flowers, seeds – not just an amazing looking flower, and typically used as a tall showy accent back drop in many cottage style gardens.
- Seed Count: 40
