This is the Asian version of the lady slipper orchid called Paphiopedilum. Since these are generally single flower and single stem plants, we generally ship them in bud, anywhere from 1 to 4 weeks from opening to minimize the chance of damage to a flower.
These are potted in sphagnum moss. Water with filtered/drinking quality water when it starts to feel dry. Typically this will take about one week. Fertilize once a month with an orchid fertilizer.
