This should be an exciting new Bulbophyllum cross. Bulb. Star of Sumatra is Bulb. (echinolabium x sumatranum), we crossed this with Bulb. virescens, which gets large umbels of green-yellow flowers with a dark pink lip. Expect colorful flowers with a yellow to green background overlaid with a red tessellation, and a dark pink to red lip. Each flower spike should have multiple flowers open at the same time. The picture shows the first seedling to bloom from this cross.
