Well-behaved, Persicaria amplexicaulis 'Alba' is upright, clump-forming perennial boasting narrow spires densely packed with small, bell-shaped, white flowers held on long, graceful wands over a long season. Blooming from midsummer to fall, they rise well above the foliage mound of large, oval, pointed, mid green leaves.

  • Typically growing up to 3-4 ft. tall and wide (90-120 cm), it thrives in average, medium to wet soils in full sun to part shade. Best flowering occurs in full sun, however light shade will be appreciated in hot and humid summer areas.
  • Trouble-free and easy care, this is a welcomed addition to beds, borders, where Persicaria amplexicaulis provides long summer to fall bloom in the perennial border. This is also an ideal candidate for bog gardens, along ponds and streams or in naturalistic meadows. Excellent as a tall groundcover when planted en masse. Underplant it with spring blooming bulbs for color prior to the lush spring growth.
  • Attracts birds and butterflies, but deer and rabbits ignore it!
  • Shear plants in fall if desired to remove spent flowers.
  • All plant parts may cause skin irritation on contact and stomach upset if ingested.
