I think the main problem is that for the most part purslanes just aren't available in local nurseries. So not too many people are so into them. Yes, blame it on the nursery industry!
The site with the Texas Superstar info:

So it was the whole Yubi Summer Joy series of P. umbraticola. And on another site I'd come across the fact that P. oleracea 'Yubi Summer Joy Scarlet' is recommended as a good edible purslane which ALSO has pretty scarlet flowers, double duty plant, you might say.
Of course, if you wanted to broaden the scope of the site, you could always include something else.
Ornamentals with edible flowers or leaves comes to mind...but that's just because I like edible plants here and there in the garden. Ha! Little snacks in the garden! I'm organic, so there is no problems with the edibles. Right now, I am snacking on mostly Yellow Pear tomatos and figs (not ornamentals) and purslane...unless you count the herbs, mints and nettle mostly. Unfortunately, the nasturtium flowers give out once summer starts. My friend is trying to get me to grow squash just for the flowers, which are pretty darn good, according to her.
