I went crazy for Sobralias last year, and bought a piece recently cut off of a Sobralia from an orchid sale in San Diego last fall. I was told it was a mirabilis, white with lavender lip and it did not disappoint. Amazing how you can take a chunk that looked as if it was cut off with the sharp edge of a large shovel, and less than a year later have a blooming plant less than 2 feet tall.
