My favorite vandas are the tessellated ones, like this one. This is my only one like this though - I have two others, one spotted and one solid color.
I dig contrasts and patterns, so this one with the white background and heavy dark veining is perfect for me. If I got another, I would seek out a white background with the darkest tessellation pattern I can find. Thin lines are better in my book also.
As all of you who keep orchids know, pictures just don't capture the sparkle and true colors of these flowers. This one is no exception.
