Stinkwort

A poisonous, non-native, profligate weed, Stinkwort, is moving at an explosive speed into Woodside from I-280, and now is the time to fight back before this year’s growth triggers deeper penetration into our Town next year.

Known scientifically as Dittrichia graveolens (L.) Greuter, Stinkwort, a native of Southern Europe and North Africa, is characterized by sticky, smelly foliage which can cause contact dermatitis similar to poison oak to humans and, in rare cases, illness or death to horses and other livestock.
