Definition of Noxious Weeds

Noxious weeds are defined by the Washington State Noxious Weed Control Board as non-native, highly destructive, invasive, competitive, and difficult to control or eliminate. These exotic species not only reduce crop yields and destroy native plant and animal habitat, but they can damage recreational opportunities, clog waterways, lower land values, and poison humans and livestock.

About Bee-U-Tify seeds 

As a few of these native species are toxic to livestock, please plant these seeds in managed garden beds where livestock will not have access.

Although these species are native to Washington, the combination of grassland, rangeland, and ornamental species used in the blends do not occur in the wild, so these seeds are intended for yards and gardens only. Please do not scatter them in natural areas. Western Washington blend six mix contents: farewell to spring, fleabane daisy, camas, globe gilia, Oregon sunshine, bigleaf lupine, western yarrow, gumweed, riverbank lupine, self heal, annual coreopsis, fragrant popcorn flower, Oregon iris, and dense-flower willowherb.
