Ageratum, is a genus of 40 to 60 tropical and warm temperate flowering annuals and perennials from the family Asteraceae, tribe Eupatorieae. Most species are native to Central America and Mexico but four are native to the United States. They form tussocks or small hills. They grow to a height of 75 cm. The opposite leaves are cordate or oval, hairy or tomentose. The margins are slightly toothed or serrate. The leaves form compact clusters. The fluffy flowers are lavender-blue, pink, lilac, or white; and spread in small compound umbels. They give small, dry fruits.
Ageratums are grown for their flowers, especially A. houstonianum. Most common ageratums, "Hawaii" for example, are a short 25 cm when fully grown. Tall ageratum are also available in seed catalogues. The blue-coloured varieties are most popular and common, but colours also include violet, pink and white. Their size and colour makes ageratums good candidates for rock gardens, bedding, and containers. They grow well in sun or partial shade, from early summer to first frost. They are quite easy to grow, producing a profusion of fluffy flowers all season long.
