Jason, I'm fairly sure these are both edible leaf hibiscus, a.k.a. south sea salad tree, a.k.a. bele tree, Abelmoschus manihot, which have highly variable leaves from one selection to another. Baker Creek sold them last year, though I had bad luck with shipping and mine arrived half dead, soon to be all dead...weather was just too warm for when they shipped. I'll try them again some day.
Here are some pictures of a few varieties common in the trade which might be yours:
