Brisbane garden

Spotted this beautiful orchid in my daughter's garden in Brisbane before we left today. The house they bought had belonged to an elderly couple and has a lovely old established garden. Along the back fence is a raised bed full of beautiful plants all of which now get very little attention (actually no attention) and yet keep growing beautifully. I haven't seen this orchid in flower before, in fact I wasn't really sure what the plant was. It is growing in a hollowed out old stump in the garden and it wasn't until I saw the flower that I realized it was an orchid. I always thought they were very delicate plants, however this one has thrived on neglect I'm sure, so they must be much hardier than I thought :)
