Characteristics:
Field morning glory is a perennial with trailing to twining stems from 20-200 cm long The leaf blades range from arrowhead-shaped to ovate-lanceolate. The tips of the blades are blunt to pointed and range from 2-6 cm in length. The petioles range from 5-30 mm long.
The broadly funnel-shaped flowers are usually in clusters of two to three. The white to pinkish-purple corollas range from 1.5-2.5 cm long. The lobes of the stigma are narrow and slightly flattened.
Considered invasive, field morning glory is difficult to kill due to its low growth and deep, widespread rhizomes.
Field morning glory may be found in disturbed fields, roadsides, and open waste areas.
Field morning glory is native to Europe and has been introduced to North America where it is now widespread and considered a pesky weed.
In the Columbia River Gorge it may be found between the elevations of 100'-3000' from the Sandy River east to Biggs, OR.
