Check out these two Cattleya walkeriana siblings with very different flower color! Both are 'Estrela da Colina' x sib that I picked up a few weeks ago at the recent Heart O' Texas Orchid Society show. One is a very dark lavender (I'm hoping for a rubra next year, we'll see) and one is alba. First bloom on both plants.
This is also the same cross as the C. walkeriana in my icon here on OB.
