Pinkhead Smartweed (Polygonum Capitatum Punching Balls) - Polygonum Capitatum seeds can be grown to form a low-growing, spreading ground cover. A synonymous botanical name is Persicaria Capitata, and it has many common names: Pinkhead Smartweed, Pink Knotweed, Pink Clover, and Pink Fleece Flower. Pink Knotweed uses include containers, baskets, edging the front of the border or as ground cover plants. It looks especially lovely in raised beds or containers where it can spill over the edges. Pinkhead Smartweed is praised for its burgundy tinted foliage and small coral-pink round flower heads. It is a tough, easy-to-grow ground cover for sun or shade with a long bloom season.
Start Polygonum Capitatum seeds indoors in late winter for areas with a short growing season. Use quality seed starting soil and small pots. Press the ground cover seeds into the moistened soil and lightly cover. Maintain moisture until germination occurs. After danger of frost has passed, transplant the Pink Knotweeds seedlings outdoors after hardening the ground cover plants for 10 days or more. For areas with a long growing season, start the Knotweed ground cover seeds directly outdoors after danger of frost has passed. Prepare a weed-free seedbed and lightly cover the seeds with soil after broadcasting.
