Though not as commonly grown as some summer bedding plants such as petunias or marigolds, the Mexican sunflower, Tithonia rotundifolia, is a useful plant for adding height to displays, standing up to 1.8m tall. The bright orange flowers appear from late summer to early autumn and last well when cut for the vase.
Sow Tithonia rotundifolia seed in mid- to late spring. Wait until all danger of frosts has passed before planting out in a sunny, well-drained spot in the garden. Protect young plants from slugs and snails.
