Roscoea ganeshensis is a small perennial tuberous plant from the Ganesh Himal of central Nepal, grown for its purple flowers. It needs moist but well-drained soil, a mulch, and shade for part of the day to do well in cultivation.
Roscoea ganeshensis is a perennial herbaceous plant occurring in Ganesh Himal (part of the Himalayas) in central Nepal. Most members of the ginger family (Zingiberaceae), to which it belongs, are tropical, but like other species of Roscoea, R. ganeshensis grows in much colder mountainous regions. It is used as an ornamental garden plant, requiring moisture and shade in the summer.
R. ganeshensis is in cultivation as an ornamental plant. General recommendations for the cultivation of roscoeas are a moisture-retaining but well-drained soil, with a mulch of a material such as bark, and shade for at least part of the day. The species was included in a Royal Horticultural Society trial of Roscoea species and cultivars in 2009–2011. Although it had been awarded a "Preliminary Commendation" in 1999, it was not given an award in the trial. It was noted that although it remained healthy, it did not increase well, needing more shade and moisture than was provided.
According to Cowley (2007), Roscoea ganeshensis is only known from one locality, the Buri Gandaki valley in the Ganesh Himal, central Nepal, where it occurs at about 1,900 metres on a steep rocky bank.
