Cattleya have a season for a specific species or hybrid but not for the group. Now is peak time in Florida for the most types of Cattleya.
To get multiple blooms requires a couple of conditions.
Sogo Doll can bloom three times a year in Hawaii, but in Florida with our colder winter I only get two blooming seasons. The actual month can vary. With about 50 plants in the greenhouse I have flowers on one of these bloom about 9 months a year, just not the same plant. The number of times a plant will bloom is definitely tied to the number of growing months.
The president of our local Orchid society (a commercial grower of tropicals, and plays with orchids) says his Chyong Guu Cafffinch seems to be in bloom year round. He lives on Pine Island which is the best conditions in Florida and considerably better than Hawaii.
The older and larger a plant gets will increase the number of times it blooms. I believe what is happening is that the plant is blooming on different parts at different times. Much the same as if it were multiple plants.
I had a Stima Kelly Lea that bloomed almost every month. I gave one to my brother and it did not bloom for months then he got 8 spikes at once. I really believe you get about the same amount of flowers over the course of a year.
