To my knowledge, all of the plants from HD or LS have been identified. This of course excludes the oddball, one-of-kind, plant that some nursery delivered by accident (or intentionally.) Here's a list of what I've seen over the years in South Florida:
Petra, Mammay, and Gold Dust are standard. Sometimes you can find a Golden Mammay mixed in with the multicolored ones. And Yellow Petra pops up here and there.
Years ago I bought Piecrust in South Miami on a regular basis.
Then we had the first iteration of Dreadlocks, followed by Picasso's Paintbrush, AFD#5, AFD#7 (both with a variety of names) and Magnificent.
On an irregular basis you can find Mrs. Iceton and in miniature's section (usually Angel Plants stock) there's Andrew (which is not the right name, but I can't remember the correct one), Yellow and Red Banana, Batik, and Punctatum.
Publix has Gloriosum Superbum several times a year.
