Rheum SDR1863

Polygonaceae

The rhubarbs include some small alpine species, and some dramatic giants. They all provide unusual and interesting structure, often with good autumn colour.

Rheum SDR1863 is a dwarf species from high altitude in the mountains, which has shiny green leaves and red stems - just like a rhubarb should. The flowers stems are lightly branched, and carry a mass of small, pink flowers.

		Rheum alexandrae SDR4602 is a magnificent species with a crown of many not very large fleshy leaves. When it flowers it sends up a tall stem, clothed in cream-coloured bracts, overlapping and hiding the insignificant flowers and then the seeds. Surrounded by Primula sikkimensis it looks wonderful - and that is a combination to try in cultivation.
		Rheum alexandrae SDR4757 has tall flower stems, covered in triangular creamy yellow bracts, each the size of a hand. These remain after flowering, and the seeds ripen behind them, out of sight. The leaves are fleshy, many of them arising directly from the crown. Looks great with pale yellow Primula sikkimensis.
		Rheum alexandrae SDR6031 is a fine, large plant, growing in really wet places, in this case between large rocks. It has tall flowering stems, completely covered with overlapping huge, triangular, creamy bracts.
		Rheum CC4845 is a species from the Himalaya that we know very little about, except that it has grown very quickly in the few months since the seed was sown.
		Rheum CC5243 is a Chadwell collection in Nepal, and the collector's notes simply indicate that it came from open slopes. In the Himalaya, the choice is between that and forested slopes.
		Rheum SDR2817 is a small, but not tiny, species with round leaves, pointed at the outed end, turning deep red as autumn approaches.
		Rheum SDR5004 comes from high alpine limestone screes at 4400 m, in a region where summer rainfall is not very high. It short flower stems, loosely branched, over a few roundish, greyish green leaves.
