We have more of these for sale oke: (hint, hint). The plant in the picture is a selfing of our "big" old plant (nearly 4" across!) and it's the best blooming punctata I've ever seen. http://www.botanicaltd.com/images/s...ription pages/aerangis-punctata-'barbara'.htm They're one of those orchids that's beautiful even out of bloom---great spotted leaves, little raised spots all over the roots---cool looking! Every time they bloom, they get better!
I don't think they're particularly difficult to grow...we grow ours on cork plaques. Any orchid on a plaque requires more consistent attention than one in a pot since they dry out quicker. Good water quality (we use RO water) plus micronutrients are important with any orchids on plaques. I've seen photos of aerangis blooming in pots, but don't really feel this is the "preferred" method for growing them. They don't want much light and like intermediate to warm temperatures. The most special treatment they need is a bit of a rest (drier) after blooming. There's hardly a time during the year that there's not one species of aerangis in bloom for us...hmmm...kind of like slippers! They're wonderful plants. Aerangis is luteo alba var. rhodosticta, citrata and punctata are great "first" aerangis.
