Mexican Sunflower: Local Thai
(Tithonia rotundifolia)
A shrub with large green leaves and dark orange flowers. Plant height is shorter than T. diversifolia. It is often introduced for its attractive flowers and it grows about 1m tall. It grows in most soils and is moderately resistant to drought. Provide well-drained soil in full sun. Stake if necessary and shelter from strong winds. CAUTION: We caution against planting Tithonia where it does not already exist as it can become weedy.
Plants can reach up to 6 feet (1.8 m) tall and 2 feet (0.6 m) wide in just a few months. Good for companion planting.
