- Description
-
Willowherbs are in the Onagraceae family. They are annuals that are more common in cool regions but occur occasionally as a cool-season weed in warmer areas. Seedlings are small and slow to establish, but once established, plants elongate to 18 inches tall. This weed is becoming more prevalent in container nurseries, likely spreading in contaminated nursery crops. Inspect liners to prevent introduction. Prevent plants from going to seed. Willowherbs are not well managed by herbicides currently labeled for use. Herbicide efficacy rankings for this species are based on limited experimental data. This weed is similar to northern willowherb (Epilobium hirsutum)
An easy plant to get children to draw and to get them involved in seeing the beauty of the great outdoors.
