I can't seem to keep a cute almost-purple P. caperata alive but the others I've found are soldiering on valiantly. P. orba, verticillata, and prostrata were found in hanging pots.
Little clumps of P. orba and P. verticillata in mini garden, the shorter plants in the middle. To the left is an Alternanthera ficoidea.
P. prostrata has some of the smallest leaves possible, and is a dark green in very little sun:
And is almost a lime color in a pot where the sun hits for hours from mid-morning to mid-day:
Another one that I love was sold as dolabriformis but I think it may be ferreyrae.
The key to these for me, or any other succulent plants, is to propagate and get roots new going without store-peat hopelessly stuck to them. I can't keep the roots of anything alive for long in that condition. Once I get some cuttings going, I put the roots in the ground over summer, and that sometimes helps get rid of the peat. Sometimes I dig the roots back up, sometimes I just harvest all of the stems in the fall & add them to the pot with the first 'round of cuttings, or any other pot that has some space to share.
