- climbing or creeping vine with long twirling stems that can exceed 3 feet in length
- arrow-shaped leaves alternately arranged on stem; plants also produce extensive network of rhizomes (underground stems)
- white to pink funnel-shaped flowers (1 inch in diameter)
- climbing up or matting on adjacent plants or structures in lawn areas, planting beds or support structures such as fences
- non-woody perennial vine with seedling germination from early spring to late fall
- peak growth rate occurs when temperatures reach 57°F; aboveground shoots die back to ground in fall
- flowers last for 1 day and produce seed that can remain viable for up to 60 years
- Effective control must target both aboveground and underground plant structures.
- Frequently hand-pull aboveground structures prior to seed maturation to prevent re-seeding; mechanical removal of aboveground foliage will not kill underground plant parts.
- Spot treat foliage with appropriate post-emergent systemic herbicide when plants are actively growing. More than one herbicide application may be necessary to kill all spreading structures.
