I'm glad I checked this one more time before going to bed. Thanks so much for the incredibly detailed explanation. I love that.
My statement about places like HD only having ordinary plants seems to apply to those in Mpls. I've heard similar reports to yours about HDs in other parts of the country carrying a really wide selection. We never get anything other than what I stated - Dends and Phals. I've checked so many times I can't even count anymore. It's really rare to even find something like a Sharry Baby. Very sad.
Now, if you would like to tackle the other question you hinted at: Miltonia vs. Miltoniopsis I would be eternally grateful. I understand both in reference to the species, but why are most hybrids called Miltoniopsis? Maybe this should be a separate thread. Anyway, thank you again.
