Rheum alexandrae

Alexander's rhubarb

A very striking and unusual plant, Rheum alexandrae, is an ornamental rhubarb from wet ground at high altitude in different parts of south-west China notably West Sichuan, East Xizang and NW Yunnan. 

It grows an amazing spiked tower, a metre tall of  creamy yellow bracts that cover the insignificant flowers and seeds. These bracts overlap creating the most bizarre looking plant. As their native habitat is usually above 3000 metres, marshy, windy, misty but also hot on occasion, recreating their natural growing conditions can be a challenge. 

They grow well where the climate is cool. They are not considered rare or endangered at the moment but a warming climate will inevitably take its toll. 

Definitely worth a go for gardeners who like a challenge.
