Cattleya dowiana

This is the grand-daddy of all the "yellow w/ red-lip" hybrids out there, most notably Blc. Toshie Aoki and the (over) abundance of progeny. I've had several of these grow to blooming size, though only a couple actually had blooms that opened fully, ie. the petals don't appear "stuck" to the lip.

Cattleya walkeriana var. coerulea

A compact, but sprawling plant, C. walkeriana is as suitable for mounting as it is for window-sill culture -- as long as you're prepared to put a bit of extra care into it.

This picture of the coerulea (blue) variety was taken at H&R Nurseries in Waimanalo -- I purchased a couple of them and could never get them to grow and bloom quite as well as these.

Cattleya lodigesii

This is the standard pink variety of a easy-growing, bifoliate cattleya. Identical in every other respect to the C. lodigesii var. alba in an earlier post.
