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. How to grow them. Available as seed from Buckingham Nurseries |
