Can the annual Portulaca survive as a perennial in Zone 10 South Florida?
What are the differences between Portulaca, Moss Rose and Purslane?

to NGA

They are all Portulaca of some kind. I think it is a perennial treated as an annual.

I love the top bloom - I've never seen one in person~ how nice!

They should do well in Florida in the full sun. Sometimes they surprise us in certain climate zones and come back as a perennial, but living in Arizona I have only had them come back for one year so far.

Portulaca, Moss Rose and Purslane are all members of the Portulaca family. Each is a different name for a variety of the species.
Your second photo is portulaca, the first and third are known as purslane.

You can read our other threads for great information describing some differences and look at photos in the plant database.

Welcome Eve

Hi & welcome! Your plants are gorgeous! TY for sharing your awesome pics!

Your 1st & 3rd pics are Portulaca umbraticola. Not a true annual, though you may not be far enough south for it to survive perenially.

The 2nd pic is P. grandiflora. I suspect that's not a true annual either but haven't gathered enough evidence to be sure.
Moss Rose (Portulaca grandiflora)

The last pic looks like P. amilis. A perennial that is more hardy and survives over winter here, so yours should also.

Purslane traditionally refers to P. oleracea.
Common Purslane (Portulaca oleracea)

But a couple decades ago, P. umbraticola was incorrectly introduced in commerce in the US as a cultivar of P. oleracea and that nickname is now quite confused.

There are cultivars of P. oleracea developed for nutritional/culinary/palatability attributes, but not in regard to ornamental blooms.
