Rlc. Memoria Anna Balmores 'Convex' is my favorite orchid. It has 5 1/2" bright, fragrant blooms that are self supporting and don't need to be staked. It blooms on every new pseudo-bulb. It's a vigorous grower and very disease resistant. It blooms on one or two pseudo-bulbs at a time, starting in October each year. Last year, new blooms kept opening for 10 weeks. I don't know if all clones of this plant are as good but this one is a real performer.
