Rumex sanguineus var. sanguineus

Product Image
Emerging from its tap-rooted base, Rumex sanguineus var. sanguineus showcases a vibrant display of mid- to dark green leaves, each adorned with strikingly prominent beetroot red veins that trace intricate patterns across their oblong forms. As early summer arrives, the plant sends forth upright flower stems, branching gracefully and bearing tiny, star-shaped flowers that transition from green to a rich hue of red, eventually giving way to dark brown fruit. This herbaceous perennial forms dense clumps of foliage, and is suitable for a range of soil moistures and types, but is particularly glamorous for boggy, marginal areas.

How to care for Rumex sanguineus var. sanguineus:

Grow in boggy soil, still or slow moving water up to 0-5cm (0-2”) deep. Plants benefit from a hard clipping back after blooming, to rejuvenate the foliage. Lift and divide large clumps in early spring before the plant has flowered. To limit the plant's spread restrict it in an aquatic plant basket and remove unwanted growth in early spring before flowering.
