I think culture makes a difference too. My cernua bloomed regularly with 2-3 blooms. Leaves were smaller than those I had seen at shows with 7-10 blooms. I thought that there were better cultivars available. Undoubtedly there are, but I have increased the bloom count on mine to 5-7 blooms, 2-3 times a year with a regular fertilizer schedule, more light and a quick dry of roots by mounting the plant. Leaves are about 25% bigger too.
