C. Walter Wolff (C. maxima var. alba x violacea var. alba)
Cattleya maxima var. alba has gorgeous white flowers with yellow in the lip, several of which bloom per inflorescence. C. violacea var. alba is a compact plant that has crystalline white flowers with a touch of yellow in the lip below the column. We are looking forward to a really nice alba primary hybrid from this pairing.
(About 2+ years from blooming size.)
