Aster is a genus of perennial flowering plants in the family Asteraceae. The name Aster comes from the Ancient Greek word ἀστήρ (astḗr), meaning “star”, referring to the shape of the flower head. 

Aster can be found in soil which is typically low in Calcium and Phosphorus but high in Sulfate, Cilicon and Selenium. If this plant is a common finding in your field, you may lack organic matter and have hard and salty soil.

Asters can grow in all hardiness zones.
