Field bindweed (Convolvulus arvensis)

Also known as: Creeping Jenny, lesser bindweed, small bindweed, common bindweed, morning glory

Field bindweed is a perennial vine that forms dense, tangled mats that smother native plants and crops. It’s long-lasting seeds and ability to regrow from small root fragments allow it to spread rapidly and make it difficult to control.

Description:

Habitat:

• It grows in a range of sun and soil conditions.
• It thrives in areas that receive full sun and is capable of tolerating periods of drought.
• It is commonly found among field crops, pastures, forested parks, and residential settings including driveways and gardens.

Impact:

• Field bindweed’s long-lasting seeds and extensive root system allow it to grow rapidly and make it difficult to remove.
• Its dense growth smothers native vegetation and crops preventing them from accessing resources.
• It also reduces crop yields.

What you can do about it:

• Field bindweed requires an integrated pest management strategy for control. A single control method is not enough to remove it.
• Prevention is the most effective control. The best way to prevent it from establishing is to remove seedlings before they become established and prevent existing plants from producing seeds.

Look-alikes:

Hedge bindweed (Calystegia sepium) is a native plant that is often confused with field bindweed. It has larger leaves and flowers than field bindweed. Hedge bindweed is native to Oregon, but it can outcompete other plants and crops in certain settings.
