Knotweed Pink Punching Balls Polygonum Capitatum is a perennial native to China. Knotweed Pink seeds can be started indoors 8-10 weeks before last frost, and also know as Persicaria Capitata, Pinkhead Smartweed, Pink Clover, and Pink Fleece Flower, this low-growing, spreading plant features burgundy tinted foliage with lance-shaped leaves blooming all season long with small coral-pink, globe-shaped flowers. Pink Knotweed looks lively spilling over the edges in containers, pots and hanging baskets, and Persicaria Capitata makes an outstanding low maintenance ground cover and edging plant.
