Mexican sunflower is a tall and colorful annual, excellent for borders and foundation planting. Because of its large height and rangy habit, Mexican sunflower needs space. In full sun, it will bloom from June until first frost. Cut flowers last several days in water and retain their bright orange color well.
Hardiness and Range
A native of Central America, Mexican sunflower is hardy in zones 5 to 10 where it will self-sew. If it is started from seed indoors, it can be grown successfully in zone 4.
Full sun is best for Mexican sunflower, but it will grow and flower in filtered sun. Heat and draught tolerant, it prefers well-drained soil.
