@hawkeyewx Dan,
Good to know. I was thinking about growing it next year, but I think I'll pass.
It was mid August (8/18) when I got my first flower (only one) on Rhythm and Blues. I got my second, third and fourth flower today on 8/21 (first one was already finished blooming). Wished I'd gotten Black and Blue this year and/or some of the other guaraniticas, since I would've a lot of flowers blooming by now. I'm growing two Amistad plants and they've been blooming for a long time.
Maybe if I saw R and B and/or B and Bloom with flowers and buds already on the plant in pots at a store, I might be tempted to buy them.
