Most of my cattleyas bloom in the fall or winter. My phals bloom from January through the spring. In South Florida we tend to like orchids that bloom between fall and spring because that's when we have our best weather. I do have some vandas and they're summer bloomers. If you look around, you can find some cattleyas that bloom in the summer. Some of the phalaenopsis with short spikes and small flowers tend to be summer bloomers also.
