Physical Characteristics: Several different species in the daisy family are popularly referred to as dandelions, and all are quite similar in appearance. The most common on the coast is not the true dandelion (Taraxacum officinale), but flatweed or cat’s ear (Hypochaeris radicata). All have the form of a flat or erect-leaved rosette, with deeply lobed leaves spreading from a central point. From this central point one to many flowering stems arise (plants growing in better conditions will produce the most flowering stems). Flower heads are yellow with numerous overlapping “petals”. Each “petal” is really a small flower in itself with a single petal-like structure more properly referred to as a ligule. They lack a differently coloured centre such as many daisies have. The seeds of all are carried in typical dandelion “clocks” with each seed having a parachute of white spreading hairs to help its dispersal.

Dispersal: Seed is wind-spread, or spread in contaminated soil or hay and other stock feed.
