That looks fantastic, Donald! I was following in your footsteps & a member of your fan club & didn't even know it. I think your last pic is P. pilosa which, from what I can find from investigating, has flowers exactly like P. amilis but, like you said, has "pine needle" leaves like P. grandiflora, and some hairiness on its' stem. The P. amilis leaves are flat & have some width, not hairy. (Pilose means hairy.)
This Australian guy is into Portulacas too, some overlap in the species he's documented in Australia:

USDA state search lists these species for TX, but some entries have zero pics:
Portulaca grandiflora rose moss
Portulaca halimoides L. silkcotton purslane
Portulaca parvula
Portulaca oleracea L. little hogweed
Portulaca neglecta
Portulaca oleracea L. ssp. granulatostellulata
Portulaca retusa
Portulaca pilosa L. kiss me quick
Portulaca cyanosperma
Portulaca mundula
Portulaca suffrutescens Engelm. shrubby purslane
Portulaca umbraticola
Whenever you might find those pics, pls share 'em, in this discussion or a new one dedicated to the various different plants you've been so lucky to encounter.
Sandra, nice pots! All of the plants being discussed are Portulacas, by genus. Your first pic is Portulaca grandiflora. The 2nd pic is Portulaca umbraticola. Each has various common names, it's pretty confusing to try to discuss them that way.
Until P. umbraticola entered into commerce a few decades ago, purslane only referred to P. oleracea, which only has small, yellow, single flowers, and is the edible cultivated nearly everywhere, worldwide, but called a weed in the US. Never sold as ornamental AFAIK.
I did watch my flowers open this morning. Within about 20 mins, the flowers went from not even pink at the edge of the buds to fully open flowers. P. pilosa flowers are similarly short-lived, which makes me now understand one of its' common names, "kiss me quick." Halfway through the growing season & this has all been a fascinating learning & observation experience, and these plants will definitely donate a lot of organic material to the soil after frost knocks them down.
