People throughout Western Washington are reporting unusual numbers of a poisonous weed called tansy ragwort.

The state Noxious Weed Control Board’s Wendy DesCamp says the plants are probably thriving because of the cooler weather this year. The plant grows to 4 feet tall and has daisylike yellow flowers with 13 petals each.

The Kitsap Sun reports ( http://bit.ly/nWtxO0) the plant can kill cows, horses and goat and is also poisonous to people and pets because of its high concentration of dangerous alkaloids.

Kitsap County’s Dana Coggon says it’s the worst she has seen locally.

The Department of Agriculture recommends pulling the plants out by the roots and placing them in a plastic bag to avoid spreading the seeds. Plants should not be composted.
