NOTE: Hedge bindweed is native to Oregon but has the ability to suppress other plants and crops.

Also known as: morning glory, bulge vine, heavenly trumpet

Hedge bindweed is a climbing vine with a deep root system. It forms dense, tangled mats that smother native plants and crops. Its long-lasting seeds and ability to regrow from root fragments allow it to spread quickly.

Description:

Life Cycle:Perennial (life cycle lasts more than one year)
Early Detection and Rapid Response species:No
Height:Up to 10 feet (3 meters) long
Leaf Description:Leaves are arrow-shaped and have a prominent heart-shaped base.

The tops of the leaves are medium green while the bottoms are light green. They grow alternately along the stem.
Fruit & Flower Description:Flowers are white or sometimes pink. The petals are fused at the bottom to form a trumpet or funnel shape.

Two large, green bractsBracts Leaf-like structures below a plant’s flower. are found at the base of each flower. They are replaced by small, oval seed pods.
Bloom Time:April to September

Habitat:

  • Hedge bindweed grows in a variety of sun and shade conditions and can grow in poor soils.
  • It readily climbs trellises, fences, and neighboring plants. In open areas, it sprawls haphazardly across the ground.  
  • It is commonly found in fields, farms, urban parks, and vacant lots.

Impact:

  • Hedge bindweed’s dense growth smothers native vegetation and crops preventing them from accessing light, water, nutrients, and space.
  • Its ability to grow on other plants and crops make it a nuisance in agricultural settings by reducing crop yields

What you can do about it:

  • Hedge bindweed’s deep root system and long-lasting seeds, require an integrated pest management strategy for control.
  • Prevention is the most effective control. When working in areas near hedge bindweed, clean your boots and equipment to avoid transporting its seeds to new locations.
  • Manual removal is recommended when removing existing plants. Spring is the best time to manually remove hedge bindweed.
  • For small patches, loosen the soil with a pitchfork to remove the entire root system. Consistent monitoring is needed for manual removal to be successful.
  • Tilling is effective at reducing this plant from spreading for larger patches. This practice will not entirely remove the plant.
