Aster is the Latin word for "star." This refers to the flower's star-like shape.
Another myth states that asters were created from the stardust when Virgo looked down from the heavens and cried. Virgil, the poet, thought that the altars of gods were covered with these flowers.
Also, asters were placed on the graves of French soldiers to represent afterthought.
