Paphiopedilum Stardust Flight x Spellbound. Bought it on the street in San Francisco last year, carried it back on the plane as hand luggage, and it then proceeded to sulk all winter (in common with many of us up here). Lo and behold, after careful feeding and a year under the lights, it popped one huge bloom, with another two buds right behind it! First time I've managed to re-bloom a Paph.
Oops. Just realized this should have been in the "Orchids in Bloom" forum, and also I didn't rotate the photo upright. Thought I did, but guess not...
