Pilosella Aurantiaca - Cultivation and Uses

Cultivation and Uses

P. aurantiaca is widely grown as an ornamental plant in gardens for its very decorative flowers. It has been introduced into Australasia and North America and escaped from gardens and is considered an invasive species in some areas. It is found across Canada and the north of the U.S., reaching more in the south on the coasts. The plant is easily removed (until it seeds back) by ploughing or salting, and it cannot be controlled by mowing because it regularly reproduces vegetatively. It is on the noxious weeds and/or quarantine lists of Colorado, Idaho, Montana, Oregon, Washington, and regions of British Columbia, with cultivation usually prohibited. In Alberta, it is not considered a noxious weed except locally. In Australia, the plant is considered a noxious weed in Tasmania and it is quarantined from the country. In New Zealand, the plant is closely watched and attempts at control are made.
