Identification: Alternate arrowhead-shaped leaves can be pointed or blunt at base; creeping and twining stems. White-pinkish bell/funnel-shaped flowers that close in the afternoon and reopen the next morning. Can be confused with morning glory, which has larger flowers and leaves.
Impacts: Forms large patches that are difficult to control. Outcompetes native plants and reduces crop yields, especially potatoes, beans, and cereals.
Management: Very difficult to eradicate. Pulling is only effective for seedlings or young plants before extensive root system is established. Can be shaded out or smothered with dense plantings. Refer to PNW Weed Management Handbook for chemical control options.
