Tansy

Portland, Oregon   Tansy Ragwort is popping up here and there.  The Oregon Department of Agriculture says what’s out there now is a fairly normal population.  You can still spot it in acreage and along the roadside.  The tall slender stocks sprout heads that look like mini sunflowers.  In fact Tansy is native to Europe and it is a member of the Sunflower family.

Tansy contains alkaloids that are deadly to most livestock and horses.  All parts of the plant are poisonous.  The alkaloids can taint honey and be transferred through cow’s milk to humans.  An individual plant van develop up to 200,000 seeds that can stay viable in the soil for 15 years.

Pulling, and spraying are well known methods of keeping the plant from over populating.
