Rheum close to australe CC7492
10 seeds per packet. Seeds are harvested from plants grown by us from seed collected by Chris Chadwell at an open slope location at 4000 metres on his 2013 Borderlands Central Tibet Expedition. A colossal, ornamental rhubarb with a close affinity to R. australe that produces huge, thickly textured, heart-shaped foliage and towering, red flower spikes in summer. This year our plants produced flower spikes up to 2.5 metres tall. Moist, humus rich, well-drained soil in sun to semi-shade with plenty of space and deep soil to grow well. Warm germinator.
