Asteraceae (Sunflower Family) – Also called the Daisy Family, it’s the largest family of flowering plants. In fact, if all the known species of flowering plants on earth were randomly lined up, every fourth one would belong to the sunflower, orchid or legume families.
According to Wikipedia, the Asteraceae consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales.
Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees.
The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats.
Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antartica.
The sunflower family is rivaled in size only by the orchid family (Orchidaceae) with approximately 20,000 species and the legume family (Fabaceae) with about 18,000 species.
