This is a large semi-alba with two traits that I like in cattleyas. First it blooms on every new pseudobulb for the year. That's usually two pseudobulbs per lead, per year. The other nice trait is that they don't all bloom at once. I have three leads and six new pseudobulbs and they've been blooming two at a time. That means the plant has flowers on it for about three months.
Wow ma man!!! Nice flowers. I'll have to look for it on the opportunity table. You do grow awesome orchids. Must be nice to have all that sun and warmth. Keep it up.
