Rheum palmatum tanguticum - 2026

Rheum palmatum 'Tanguticum' is a dramatic perennial featuring large, deeply lobed palmate leaves and tall, imposing flower panicles that emerge in summer. The flowers are greenish-pink, forming dense clusters that create a bold architectural statement in borders, bog gardens, or near ponds. Its striking foliage and towering flower spikes provide texture, height, and visual interest, while attracting pollinators such as bees and butterflies, enhancing ecological value.

It thrives in full sun to partial shade in moist, fertile, well-drained soil, ideally with consistently damp conditions. Medium-maintenance, it benefits from regular watering in dry periods and requires ample space to accommodate its large growth. Non-native to the UK, it is valued for its ornamental impact and dramatic presence in large-scale or wildlife-friendly planting schemes.
