Botanical name: Tithonia rotundiflora     Family: Asteraceae (Sunflower family)

This is a superb plant that deserves to be better known. In its native Mexico it grows to 6 ft or more, but here it will only reach 2-4 ft. They form large, compact plants and produce their single, dahlia-like flowers very freely. The flowers are yellow to orange and about 3 inches in diameter. Grow the plant in full sun, a light soil and fertilize it regularly. Try it – your neighbours will want to know what it is.
