Cattleyas for cool climates

[rbarata]

I wonder if there are catts that could be grown outside with the conditions bellow. I believe the most critical is the winter.

My climate is:

Summer - upper 90's (35º C day) + 70's (20º C night) and HR 25% max

Winter - low 50's (12º C day) + low 40's (4º C night) and HR 80% min

Plenty of sun most of the year.

These are average readings, it can go to extremes.

Thank you
