Sanguisorba officinalis 'Lum' - 2026

Sanguisorba officinalis ‘Lum’ is an elegant form of great burnet prized for its upright, graceful spikes of deep wine-red flowers that appear from summer into early autumn above finely divided, grey-green foliage. The loose branching habit of its wiry stems allows light to pass through, giving it a delicate, air-borne quality that contrasts beautifully with deeper, more solid planting. Its long flowering period and striking dark tones make ‘Lum’ a fantastic choice for informal borders, pollinator mixes, and gardens looking for late-season drama.

Beyond its decorative appeal, ‘Lum’ attracts bees and butterflies, adding ecological value during the later months. It tolerates a range of soil types so long as moisture is maintained (but never allowed to dry out completely), and it thrives in full sun to partial shade. Once established it demands little beyond occasional support in windy spots. Non-native to the UK, it combines strong ornamental value with good garden performance.
