About plant names...

Orange hawkweed is native to central and southern Europe, but after its introduction to other areas of the world as an ornamental plant, it has become a bit too widespread in some areas. It is considered an invasive species or noxious weed in several U.S. states, two Canadian provinces, Australia, and New Zealand. Sure is pretty though.

Identification: Plants are 8-24" (20-60 cm) high. Leaves are mostly at the bottom, spatula-shaped and very fuzzy, up to 5" (12 cm) long. Leaves, stems, and stolons produce a milky latex when broken. Tall fuzzy stems support small clusters of bright orange flowers with paler orange centers, each ½-¾" (1.3-1.9 cm) across. Flower rays have squared off tips that have several serrations. There is only one orange hawkweed (vs. more than a dozen yellow varieties), so these are relatively easy to identify.

This hawkweed comparison table is an aid to identifying hawkweeds and similar-appearing species.
