I am just learning about the cymbidium family. After I bought my first two in bloom, I sort of went nuts and bought a whole bunch of them online from someone who was selling bare-root bulbs for $.99. I have no idea if the ones I bought are heat-tolerant or not. Do the heat-tolerant ones also tolerate the cold?
I guess now I'm worried that if I keep my cymbidiums all together outside for the chilly fall nights, the heat-tolerant ones won't like the chill as much and may get damaged
Jenn you made me smile. Don't worry when I first started with cymbidiums I did not know they could not grow in Florida or most parts of the country for that matter. Warmth tolerant and heat tolerant breeding is relatively new and most good hybrids are not readily available. Standard cymbidiums are normally larger with bigger bulbs "generally speaking", they are also more commercially available. I don't want to confuse you but there is also an intermediate variety with smaller leaves and flowers some will take warmth but in general most like it cool. The state of the nursery you obtained your plants will give you a good indication of their cultural requirements
Intermediates will probably work very well in your area, the plants are more controllable and there is a good chance the smaller stature of the Asian varieties was bred into them. You are right, with warmth tolerance comes reduced cold tolerance
