Tiffany: Callisia fragrans is a great "dangler" plant! Was it you who posted a photo awhile back where you'd cut holes in the sides of a pot and had Callisia pups planted in the holes? I thought that was a great idea, I can just picture them covering an entire pot and dangling out the top, over the edge and down the sides! A few years ago I had two pots of Callisia in this double metal planter on my patio and the trailing stems ended up touching the ground and taking root in the soil of a flower bed next to the pool. I ended up pulling them all out. It's listed as a category II invasive here in Florida. I have a few growing behind my deck amidst a Monstera deliciosa and other stuff and so far they are contained to that flower bed. I had one of the variegated ones that I put in the ground and it took over a huge area and was so pretty but the dog trampled it all down and we dug them all out and threw them away. I really wish I'd kept one of the variegated ones because they are really pretty. This a picture of the double planter from three years ago:
Another one that takes over but much more so than the Callisia is
Cashmere Bouquet (Clerodendrum bungei) over that bed and the lawn outside the bed and growing up through the wood deck.
Don't get me started on that one. I keep telling my husband we need to get out there and try to dig it all out ... the blooms are fragrant and so pretty but it is extremely invasive and has already taken over and killed Pentas and Lantana and some other things in one bed.
