Paphiopedilum Greyi is (godefroyae x niveum). It is a great miniature hybrid with clear white flowers with red freckles. Like other Brachy hybrids, these like to be grown warm and shady. They are great for growing under lights.
This hybrid was originally registered back in 1888. Since hybridizers have been improving both parents with selective breeding, these promise to be better than the older versions of this cross.
