Sure looks like Portulaca to me.

They are both in Portlacaceae, but the Calindrinia has gray green leaves and the C grandiflora blooms purple, with a different shaped flower.

Look at the bottom bright pink flower, it has the same stamens and leaves. Portulaca oleracea ..

Janet...I totally agree with you. So does this mean my pictures need to be moved once again?? They started out as calandrinia grandiflora....got moved to portulaca....but now me thinks they should be moved again, but this time to Purslane (Portulaca oleracea).

I would take that step Ginger!

Taken and approved....hopefully not to be moved again :rolleyes:

Hey Evan...could you close this now please?

I am confused!?
Are portulaca, cisanthe and calendrinia ---all the same plant?

Very possibly Portulaca umbraticola, Ring-pod Purslane, which Portulaca oleracea is often misapplied to.

Can you show a close-up of the seed capsules?

Mahalo, Dave

Since all 4 pictures shown are mine a pic of the seed capsule will have to wait until it blooms this year as I don't think I have one.

When it does flower and produce fruit, a simple character to tell the species apart is that Portulaca umbraticola has a saucer-like ring around the seed capsule, and Portulaca oleracea does not.

Nice comparison Lin!

Hi Dave, great to see you here! I had to google to find the comparisons.

Have some similarities but my opinion: these are not Portulaca oleracea.
Rather I agree with Paul, Portulaca umbraticola, but how he said is need to see the seeds capsule to be sure.
The plants in photos above are somewhat different from those which I saw until now in the wild in Texas.
Maybe they are a cultivar of Portulaca umbraticola variety/subspecies from South America.
Here

a very interesting article, which bring some explanations about the misapplied names for the cultivars ‘Wildfire Mixed’.
The South America's origin of these cultivars are mentioned in Flora of North America, here:

I always thought Portulaca oleracea had only yellow blooms while Moss Rose (Portulaca grandiflora) had blooms of pinks, yellow etc. which gingin's photo's remind me of.

Portulaca grandiflora has cylindrical (needle-like) leaves.

Most natural Portulaca have smallish flowers.
It is the hybrids that went to school and came back with a big head!

Mine was bought at Home Depot...all it said on the tag was Purslane if that helps at all.

Thanks Gingin,

That's a common name for Portulaca with spoon shaped leaves. The fruit capsule will show which species of Purslane that you have.

I'll jump in to say that I beleive that the photos are all P. umbraticola. We have been having this same discussion on the Purslane-Portulaca forum and it is not just confusing here but around the world. I can suggest a name change for you if you'd like Ginger.

The Portulacaceae family includes plants called Portulaca, Purslane, and Moss Rose aamong many other less common names. All over the country, and perhaps the world, there is mass confusion about the latin names and I have found even some nurseries are confused. I was given a lesson by a grower and this is my take on the purslane plant which I adore.

P. Oleracea = Wild plant with small yellow (usually) flowers and it is edible. Portulaca oleracea is called common purslane.

Portulaca: P. grandiflora = Showy, many colors, spikey leaves, double blooms. Called Portulaca by most nurseries and growers. Some call it Moss Rose. Portulaca grandiflora is also known as Moss Rose.

P. umbraticola = Showy, many colors, usually a single petal formation but there are more doubles showing up. The leaves are paddle shaped. Called purslane by most nurseries and growers.

Ginger, I am certain yours are the last, P. umbraticola.
