If it had not been for a sweet mother-in-law who always had "moss" blooming in two big pots by her porch in East Texas, I would have been mystified as you. They certainly didn't look like any moss I had ever seen, especially with the bright, multicolored flowers. I later learned it was frequently called "moss rose" and then that it was actually a portulaca. The plant your mother called "moss", with its yellow flowers, is probably Portulaca oleracea, also referred to as common purslane or little hogweed. It grows virtually worldwide in warm and temperate climates, and is usually considered a weed. It has long been used in North America as a potherb and medicinal plant, probably since before the arrival of the first Europeans.
The plant my mother-in-law grew was, I believe, Portulaca grandiflora. This is the cultivated species more often referred to as a "moss rose." Unlike Portulaca oleracea, Portulaca grandiflora is not a native, but is the one most seen in cultivation. It blooms only when the sun is shining, in many bright colors.
If this still doesn't appear to be the flower you are trying to identify, please follow the directions to send us a picture on the first page of "Ask Mr. Smarty Plants."
