Invasive orange hawkweed

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. Orange hawkweed (Hieracium aurantiacum) grows 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.

Some native plant alternatives are:

  1. Oregon sunshine
  2. Douglas aster
  3. Orange sneezeweed
  4. California poppy
  5. Arrowleaf balsamroot
