Erigeron are hardy or half hardy perennials that are native to Northern America.
Depending on the species of Erigeron they may flower from the start of summer through to the beginning of autumn.
They bear daisy like flowers of many colours, including orange, pink, white, purple and yellow.
They grow in height from 10 to 90 cm making them great to use as edging plants or in the border. A common name of Erigeron is Fleabane.

It is best to sow Fleabane seeds on the surface in either early spring or early autumn. Erigeron like to grow in a sunny or partially shaded area of the garden that has good drainage. If you prefer you can start growing Fleabane indoors then they should be prepared about 8 weeks before they are due to be put out at the beginning of spring before the last frost, or at the beginning of autumn.
Erigeron plant species such as Fleabane are quite easy to maintain; they should be deadheaded once flowering has occurred and cut back to ground level in the autumn. They will require a light feed, and should be divided every three years to maintain vigorous growth. If you require more plants then they can be divided in the spring or autumn.
