Comment |
Upright form. Sunflowers need long, hot summers to flower well. Effective in borders. Attractive to bees. Needs supporting. Sunflowers are supposedly allelopathic: their roots give off a chemical that inhibits the growth of other, nearby plants. "Sunflowers are easy to grow in any well-drained, neutral to slightly alkaline soil. Add lime if your soil is acidic. Fertilize the bed with rotted manure or a balanced chemical fertilizer for maximum growth. The taller cultivars may fall over if not given support.
Available as seed from and The Seed Site in the UK with many cultivars from Plant Lust in America |
