Mile-a-Minute

PLANT INFO:

Mile-a-Minute (Persicaria perfoliata)

  • Leaves are alternate, light green, 4- to 7 cm long and 5 to 9 cm wide, and shaped like an equilateral triangle.

  • Its green vines are narrow and delicate becoming woody and reddish with time.

  • The vines and the undersides of leaves are covered with recurved barbs that aid in its ability to climb.

  • A vigorous, barbed, vine that smothers other herbaceous plants, shrubs and even trees by growing over them.

  • Growing up to 6 inches per day, mile-a-minute weed forms dense mats that cover other plants and then stresses and weakens them through smothering and physically damaging them. Sunlight is blocked, thus decreasing the covered plant’s ability to photosynthesize; and the weight and pressure of the mile-a-minute weed can cause poor growth of branches and foliage. The smothering can eventually kill overtopped plants.
