I checked the local society Database and you are correct it is "Warmth Tolerant" . I think all that means is it not finicky about "Low" summer night temperatures to bloom.
Blooms April May here (Autumn) Not sure how long from when the spike appears to the first bloom opening but I suppose it would be a couple of months.
Peak Cymbidium flowering month here in cymbidium Heaven is August.
Cymbidium season was still going at the last meeting with Cymbidiums with Australian Native Cyms in the breeding.( Miniature flowers + Giant Foliage)
Sorry about the ramble....I am more excited about your Prosthechea, You can beam a back- cut across the big big pond. Cheers
