About Mile-a-minute Vine
An annual herbaceous plant with triangular leaves and blue fruits, mile-a-minute vine (Persicaria perfoliata) can grow up to 26 feet long. It was accidentally introduced from Eastern Asia.
It grows rapidly, covering and smothering native vegetation.
For small populations, hand pulling and repeated mowing can be effective. Pre-emergent herbicides may prevent seed germination. Systemic herbicides also work when applied as a foliar spray. Biocontrol organisms have been used to suppress populations, with some success. It may be found growing in areas subject to the Massachusetts Wetlands Protection Act; anyone planning control measures in such areas should first check with the local conservation commission, and only apply herbicides registered for use in these areas. Always read and follow the directions on the label when using herbicide.
