Caularthron bicornutum (aka Diacrium bicornutum) is a fantastic species from the northern regions of South America along with Trinidad & Tobago. Cau. bicornutum has beautiful bright white flowers that flower in late winter through early spring and release a light citrusy fragrance. These are a part of the Cattleya alliance, and we treat these the same as our other Cattleya seedlings. Plants are near flowering size in 3" pots.
