Cattleyas for cool climates

[u bada]

The catts I mentioned can handle low temps, i can vouch for that myself... gets that cold or colder in my area.

Those you named are all good down to 14 degrees, absolutely not a problem... more when you get down to 4 degrees (40's F)... you just want to keep them dry side and protected (from winds and rain)and actually they should handle that well...

purpurata, tenebrosa, lundii, bahiensis, milleri hybrid, I know for sure can handle down lower than 4 degrees... dayana was a bit iffy for me around 4... and jongheana, bradei, cinnabarina, I've heard actually do better with some warmth in winter as well... overall the brazillian laelias from minas gerias are temp tolerant, but do better with some warmth in winter around 10 degrees C (50's F).

The coldest growing laelias are mexican laelias... as i noted in last post...
