Botanical Information:
Asteraceae is huge and diverse, with over 1,900 genera and 32,000 species on every continent bar Antarctica. Plants in this family may be annual, biennial or perennial, and of vine, bush or tree form. Most are herbaceous.
Many, many ornamental, medicinal and food plants are in this family, such as daisies, dahlias, marigolds, Calendula, Echinacea, sunflowers, lettuces, Jerusalem artichoke, and yacón.
One defining botanical characteristic all Asteraceae share is their unique flower structure. What appears to be a single flower is actually a composite of many small flowers — what look to be the petal of an Asteraceae flower is actually a flower itself!
