Dahlias (Genera Dahlia, a member of the Asteraceae Family) are a genus of bushy, tuberous, perennial plants native to Central America. There are at least 36 species, but hybrids are very popular as garden plants for they large, decorative flowers.
Dahlias prefer frost-free climates, but due to their tuberous nature they can survive periods of dormancy. Therefore gardeners that experience frosts can grow dahlias, if they lift the tubers to be stored in cool, frost-free conditions over winter. Planting the tubers deep (6in) can also provide some protection.
When actively growning, dahlias prefer well watered, free-draining soils with plenty of sunlight.
