The Compositae or aster family is vast, with over 20,000 species, and is also one of the most developed families. It was named Compositae because the flowers are actually a “composite” of many individual flowers into one head. Hence, when children pull one “petal” off at a time, saying “she/he loves me, loves me not”, they are actually removing a complete flower, not just a petal.
