Tithonia rotundifolia (120 days) Stately 6' plants with velvety dark green leaves bear scarlet-orange 4–5" blooms that attract hummingbirds and monarch butterflies. My fondness for this showy flower is shared by our customers. Also known as Mexican Sunflower. The blooms continue over a long season. 1951 AAS. Annual. Especially attractive to pollinators.③
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. ~100 seeds/g.
All flowers are annuals except where noted. All flowers are open-pollinated except where noted.
Days in parentheses after a variety indicate days to first bloom.
