Regarding some Canadian vendors:
Clouds is awesome but many are seedlings, not bloom size.
Paramount has a huge selection but a lot of the bloom size plants fall into the $35.00 range.
C.R. Orchids has some good plants but his website is horribly out of date. I am supposedly getting a price list in the near future of what he has.
Orchids in Our Tropics has good quality but again, website hopelessly out of date and I e-mailed them a month ago and never heard back.
Crystal Star is good.
Those are the ones I have dealt with. Not too many places for an entire country for choices
