Rattlesnake Weed, Rattlesnake Hawkweed, Veiny Hawkweed - Hieracium venosum
|
Hieracium venosum - Rattlesnake Weed, Rattlesnake Hawkweed, Veiny Hawkweed. is listed as Endangered in Maine. Officially listed as a noxious weed in Washington state, even though the USDA doesn't list it as being found in Washington State. The fact that it is listed as a noxious weed in that state implies that it is indeed found there, and it is listed for neighboring British Columbia, so I'm including it in Washington's list here on USWildflowers.com. I suspect that with this being a disjunct location - Hieracium venosum is an eastern species - that the British Columbia and Washington populations are not native.
In traditional herbal medicine, a decoction of the plant was reputed to relieve the effects of the bite of venomous snakes, according to The National Dispensatory by Alfred Stille and John Michael Maisch, second edition published in 1879.
