We all know that Michaelmas Daisies are asters or rather members of the aster family of plants (Asteraceae). Purple coneflowers and Black Eyed Susans are also members of this family and it is these three flowers that are described below in an article by Linda Crampton which I found on the Dengarden website.
The Aster family of plants is very large and contains some beautiful flowers. Three of my favourite members of the family are the purple coneflower, the black-eyed Susan and the Michaelmas daisy. They each produce a glorious splash of colour when they bloom. They are not only attractive plants but are also associated with some interesting facts.
The family Asteraceae (formerly Compositae) is commonly known as the aster, daisy or sunflower family. The name Compositae is appropriate because of the composite flower structure. What looks like one flower is actually an inflorescence made of many smaller flowers, or florets. The inflorescence is often known as a capitulum or a head. The flowers in the central disk of the capitulum are appropriately called disk florets. Each “petal” surrounding the disk is a ray floret.
