Description
For an uncommon plant, Persicaria capitata (formerly Polygonatum capitatum) has quite a few common names, including lesser knotweed, creeping knotweed, pink-headed persicaria, pink bubble persicaria, and my personal favorite, pink pinheads. It grows in ground-hugging carpets of trailing stems and roughly oval leaves, each marked with a darker “v” pattern. They start out green but can develop a bronzy cast in full sun. Small globes of tiny, tightly packed, pink blooms reach just an inch or two in height. In my PA garden, they begin flowering in early summer, then take a break during midsummer, producing just foliage, then bloom heavily in late summer to frost. Its really cute spilling over a wall, growing as a groundcover along a path, or cascading out of a container. To be honest, I don’t know how (or if) ‘Afghan’ is different from the straight species, but that’s the name it had when I acquired the seeds. Full sun to light shade; average to moist soil. Perennial in Zones 7 or 8 and south, apparently; in cooler areas, you can grow it as an annual. Be aware that pink pinheads can self-sow to the point of becoming invasive in mild climates, so I do not recommend it for gardeners in CA or the Deep South.
