I keep a giant pot on my front steps (facing south) the past few years that's always changing. It was pansies and snaps to start this year, but I've removed most of the pansies and put heliotrope and pentas. It's about packed at the surface now, but I would still like some kind of spiller. The past few years it's been chartreuse sweet potato vine but I'd like to change it up a bit. Besides petunias, what spillers could anyone recommend for full sun on hot concrete steps? I have a lot of other mixed pots, but those get completely repotted/replanted each spring. Tell us about your hodge-pot(s)!
