    Description

    • 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)

    Location

    • climbing up or matting on adjacent plants or structures in lawn areas, planting beds or support structures such as fences

    Life Cycle

    • 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

    IPM Recommendations

    • 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.
