Annual. Also known as Mexican Sunflower. Attract butterflies and bumblebees with these tall floriferous beauties. The dressy blooms often exceed 4" across and continue over a long season.
Culture: Heat-loving plant closely related to the zinnia. Sow outdoors after danger of frost in 70–85° soil, or start indoors 6 weeks before last frost date. Tithonia sulks in the cold so don’t bring it out too soon.
All flowers are open-pollinated except where noted.
Days in parentheses after a variety indicate days to first bloom.
