About

Roscoea wardii is a perennial herbaceous plant occurring from eastern Arunachal Pradesh in India to western Yunnan in China. Most members of the ginger family (Zingiberaceae), to which it belongs, are tropical, but like other species of Roscoea, R. wardii grows in much colder mountainous regions.

How to grow it

R. wardii was included in a trial of Roscoea held by the Royal Horticultural Society from 2009 to 2011. It proved hardy with a rating of H4 (hardy though most of the UK apart from inland valleys, at winter altitude and central/northerly locations). It was given the Award of Garden Merit, subject to availability, and currently holds the award.

Where it grows

Roscoea wardii is found in mountainous regions along the borders between Tibet, Yunnan (China), Arunachal Pradesh (India) and Burma.
