They are Aptenia. They are not cold hardy further north but since the flower
the first year from seed they can be grown as annuals. They can also be
propagated from cuttings.

The yellow flowered plant is Aptenia (formerly Platythyra) haeckeliana, the
purple flowered is Aptenia cordifolia. The two will hybridize in
cultivation. The cultivars 'Red Apple' and 'Sunny Sue' are such hybrids.

Plants were purchased as simply "ice plants" and the retailer neither
remembers them nor knows what they are.
They are a marvelous ground cover that is doing very well in sunny, hot,
and
dry South Florida conditions, and I would love to recommend them to
friends
if I actually knew what they were...

Once identified then can we talk about propagating them?
I assume stem cuttings taken during an actively growing season?

Thanks
