I love my Chocolate Drop with its dark shiny leaves. It's almost ready to bloom.
It's the only really dark sedum I have that doesn't flop. My other is Purple Emperor and it flops terribly.
I've been trying to find variegated October Daphne around here for a couple of years. I saw it a few years back and should have gotten it when I saw it because I haven't seen it since. The non-variegated kind does quite well.
