Sometimes, well often, knowing what an orchid's flower will look like when a non-flowering plant is purchased is a great help. Ever so often, I will have a surprise when one of those plants blooms. I purchased a handful of the E. alata var. flavus last month and a couple are starting to bloom. The first picture is one that I sourced from the Hawaiian grower. The second was taken yesterday of one of mine in bloom. I like the lime-green coloration better than the orangey-yellow. Perhaps that green will turn to more orange with time.
