Velvetleaf (Abutilon theophrasti) is typically classified as an annual, completing its life cycle within one growing season. However, in warmer USDA Hardiness Zones 8–11, it can sometimes act as a short-lived perennial, regrowing for multiple seasons under suitable conditions. This adaptation allows it to persist in mild climates, adding to its resilience and invasiveness in certain regions.

Velvetleaf was found in the Hermiston area in the late 1980s. It appeared to be transported into the area with lambs shipped from the Midwest. It was a small infestation. The location was monitored for several years. It appeared to be eliminated with an application of soil fumigant prior to potatoes being planted in the field. Do you think you have seen it?

They are yellow to yellow-orange and have five petals that are slightly notched at the apices. When fully open, the flowers are about one-half to 1 inch in diameter. Its seed capsules are distinctively cup-shaped and bristled on the tops.

Velvetleaf causes extensive economic losses in crops in the Midwest, and the potential exists for these economic losses to occur in Oregon crops if velvetleaf becomes established in this environment.

Please check the PNW Weed Management Handbook for options for its control and contact your Extension county agent for more information.
