Daisy family

thistle plantThis is the largest and one of the most successful families of flowering plants. The scientific name of the family is Compositae, and it has this name because its "flower" is really a composite bloom made up of lots of flowers all bunched together into a head or capi-tulum. All members of the family are dicotyledonous - that is, their embryos are equipped with two seed leaves, and their leaves are not parallel-veined.

The daisy family contains some of the prettiest flowers as well as some of the most troublesome weeds. Popular garden members include dahlias and Michaelmas daisies, while the unpopular ones include wild daisies, dandelions, thistles and groundsel.

daisyThe head of a composite flower varies according to the species. In a thistle, each tiny flower consists of five petals fused to form a tube. This is called a tubular floret. Within the petals lie five stamens, whose anthers are fused into a tube. The ovary is set beneath the floret and is crowned with a bilobed stigma that sticks out of the top of the floret. The sepals develop as a tuft of hairs that carry the fruit away on the wind.

In a dandelion, each floret has a long flap-like extension on one side called a ligule. Both tubular and ligular florets are present in the same head in daisies. The central disc of a daisy head consists of numerous yellow tubular florets (disc florets), while around the circumference are arranged a ring of white ligular florets called ray florets.
