Hi Kay,
Oh your gardens are really nice. I always love the hosta and heuchera mix. Green Spice and Caramel are at the top of my list of favorites. I just bought a second Green Spice and want to pair two up with a dark one together - I'd like to get Obsidian. I really love Caramel (I have 8 of them, that's how much I love them) but have heard that Southern Comfort is similar in color only better and larger. I do have to agree with Carolyn about Melting Fire not being Melting Fire though, the tags must've gotten mixed up. Melting Fire's leaves redder, are smaller and more ruffled from what I remember. If it's any consolation, I had 3 and all three died and everyone else I've talked to theirs has either died or not doing well. Is it similar looking to the others in your garden pictures? My thought is either Palace Purple or like Carolyn said, Brownies. I've found with my Georgia Peach that it really doesn't like any amount of sun.
