Bistorta (Persicaria) affinis ‘Superba’
(Himalayan Bistort, 1-Litre Plants)

Description

Bistorta affinis (previously Persicaria affinis) ‘Superba’ is a low-growing, ground-covering perennial that is excellent as a weed suppressor and to fill spaces in shadier areas. The low-growing foliage is an attractive mid-green colour, turning red-green and bronze in autumn, and throughout the growing season the plant is clothed in a tapestry of shifting colours – dense spikes of tiny, fluffy flowers that open a delicate pale pink and slowly transform into deep crimson-red as they age, creating an attractive two-tone effect. Its neat, leathery, lance-shaped green leaves form a solid, low dense mat that develops warm, coppery-bronze tones in autumn, remaining attractive through winter. It spreads well by trailing stems but never takes over, providing a low-maintenance option for areas bordering streams or paths, on the edges of woodland or other areas with dappled shade.
