Persicaria affinis 'Superba' is a mat-forming 

 in the Polygonaceae that forms dense clumps roughly 25 cm high and 60 cm across. It bears cylindrical spikes of pale pink to rose-red flowers from June to August. Leaves are produced mainly at ground level, creating a close carpet beneath the flowering stems.

Persicaria affinis 'Superba' belongs to the genus Bistorta within the Polygonaceae and originates from montane regions of Asia. It grows as a low, mat-forming perennial that sets numerous short, erect flowering stems above a basal rosette of leaves. The flower spikes appear in summer and run through June to August, and the inflorescences are commonly retained on the plant into the colder months. Allow space for the plant to spread when placing it; groups will knit together to form a continuous carpet of foliage and summer bloom. Lift and divide congested clumps in spring to maintain vigour and replace old crowns. The upright flower stems are easy to trim after flowering if you prefer a tidier edge, but leaving spent spikes in place provides winter structure. Because of its low, spreading habit and persistent summer flowers, Persicaria affinis 'Superba' suits front-of-border planting, edging, and areas where a durable ground cover is required beneath taller plants. The combination of basal leaves and short flowering stems makes it particularly useful where a clear, low-growing layer is needed under shrubs or along paths. The plant's flower spikes often remain through winter, offering visual interest when many herbaceous plants have died back.
