Growing Tips

  • Not suitable for transplanting as it has a long taproot. The plants do not like a lot of root disturbance so it is best to pot up the divisions and keep them in a cold frame or greenhouse until they are established.

Description

The bright yellow flowers are followed by brilliant white fluffy seed heads that contrast with the attractive grey-green basal leaves. 

The species is hermaphrodite (has both male and female organs) and is pollinated by Insects.

False dandelions, like Agoseris, can be distinguished from true dandelions by their leaves and stem structure. True dandelions have a single flower per stem, whereas false dandelions often have multiple stems branching out from the basal rosette. The leaves of true dandelions also have a more deeply lobed appearance compared to the thinner, lance-shaped, and less deeply lobed leaves of false dandelions like Agoseris.
