Genus Tithonia (Mexican sunflower)

Tithonia Tithonia rotundifolia 'Torch' Photo/Illustration: Chris Curless
Common Name: Mexican sunflower
In the genus Tithonia are ten species of bushy annuals, perennials, and shrubs from Mexico and Central America that have bright orange or red daisy-like flowers on thick stems. Plants in this genus attract butterflies, bees, and hummingbirds and are useful in a mixed or annual border or cutting garden.
Noteworthy characteristics: Bushy form. Good cut flowers.
Care: Tithonia needs warm sunny weather to grow well, and full sun in well-drained, fertile soil. Shelter from strong winds. Stake if necessary and water during dry periods.
Propagation: Sow seed indoors in spring or in situ when all danger of frost has passed. Do not allow seedlings to get cold, as leaves will turn yellow.
Problems: Slugs and snails may eat new growth.
