Does anyone know what this is? annual or perennial?

WOW I dont know but its gorgeous!!! Do you have it in your garden?
Looks like Portulaca, commonly known as purslane, pigweed or moss rose. It is an annual and very easy to grow. There are a number of different species, some of which are considered quite weedy. Comes in a wide range of colors.
hmm doesnt look like species of portulaca we have here.
I've seen this the past few years. It is a cross between portulaca (moss rose) and purslane. It's really lovely. It's not hardy for me in zone 5. Sometimes the moss rose seedlings come up again the next year.
Looks like some variety of Delosperma, aka hardy ice plant.
Delosperma cooperi? There is a variety of colors from yellow, purple, orange, pink...
