Symphyotrichum is a genus of over 100 species of mostly perennial and some annual flowering plants, and are commonly referred to as Asters. All of the species are native to the Americas, except one that is native to eastern Eurasia. Individual species vary greatly in plant size and flower development depending on their growing conditions, and the genetic diversity within each species is quite considerable. Asters have composite flowers, which means their central circle consists of many disk flowers (reproductive flowers) and ray flowers (petal-looking flowers on the circle's edge that attract pollinators).
