I purchased this Wilsonara (Don Bivin ‘Challenger’ x Bouley Bay ‘Galaxy’) from the Tiny Jungle at their open house on Saturday, May 20, 2017. It is a very large plant with 10+ pseudobulbs and two 4′ inflorences that are just beginning to bloom. I really liked the color of the flowers, as it is a muted yellow rather than a fully saturated yellow.
The plant will have to be divided, as it is growing out of the pot. But I will wait for it to go out of bloom first.
