Orange Hawkweed (Hieracium aurantiacum)

Orange hawkweed_Sunlight Condos_MA_2012_07_24 (11)

This European perennial invades pastures and lawns, displacing native plants and forming monocultures. The vibrant orange-red flowers are clustered at the top of the leafless stem and you’ll see them in late spring to mid-summer. They grow about 12′ tall and produce dandelion-like fuzzy seedheads. The plant spreads vegetatively through stolons.  All parts of the plant also produce a milky juice.  The best way to get rid of it is to dig it out by hand, making sure you get all the roots.
