Mexican daisy

Erigeron karvinskianus is a dainty little daisy from Mexico, Central America, Columbia and Venezuela which is naturalised in many of the warmer parts of the world. It seems quite hardy here and seeds about, but it's an inoffensive little thing and never a nuisance. I have them growing beside some stone steps and occasionally dig up seedlings and plant them further up the steps.

The flowers open white and gradually turn pink, so you get all shades in flower at the same time. Visitors to Hestercombe in Somerset will see them growing all over the stone walls there - a very lovely little plant which flowers in a very short time from seed, so although a perennial could easily be grown as an annual!
