Last year I bought myself a Christmas present, a nice Cattleya walkeriana in bloom. When I cleaned out the tree fern fiber a month after buying it, roots were already dead. The other two were leads and still had some roots, but this piece had no roots at all.
Cattleya walkeriana grows in Brazil on trees and moist rocks at elevations up to 6000'. It is fragrant, needs bright light and blooms in the fall. It doesn't like to be disturbed.
This two-pseudobulb piece was one of three pieces that I determined to save. I propped it up in some rocks and waited. During the summer it sprouted and earlier this month it sent out a spike. C walkeriana is very interesting in the way it blooms off of new growth. It is one of only two Cattleya species to bloom this way.
The buds are now open and I got the flower picture. I will watch it and perhaps take another if the color deepens.
