Lovely and relatively easy to grow orchid the parents of which are from South East Asia. Requiring an open compost mix with say 1 part Sphagnum moss, 1 part fine bark (not composted) and one part coarse peat or perlite. Basically as long as the mix is free draining with relatively large pore spaces it will be fine. We add a little standard compost mix to our mixture because we are often away from them for periods when we are at shows and this helps to retain a little more water. Place them in a site which is dappled shade through the summer, in winter they may need protection if you're in a very cold site. We overwinter ours (in S.E.scotland) under polythene. Liquid feed helps growth and we'd recommend a balanced to high potash while they are in growth.
