Texanum would be my best guess, but in photos I can't tell that my plant or texanum is any different from acutifolium or latum. All the Lenophyllums are native to Texas and Mexico. I acquired this way back in the 70s. I believe it's a greenhouse weed and perhaps a weed in lots of circumstances. It's one of the toughest plants in existence. It seems to adapt to lots of different growing conditions and thrive. Depending on how much light it gets, what kind of light it gets and the amount of moisture it receives, it can present a variable face. The original plant (where I got the leaf that started mine) grew under florescent light 24 hrs a day in a big office building. It looked frail and delicate and grew in a tiny container without drain holes and endured haphazard care. That should have tipped me off at how tough it really is. Mine obviously does not look frail and delicate. It's not altogether winter hardy in my location, but some escaped and lived on bare gravel outside on the north side of the house for a few years without any care. It finally disappeared after a winter with really cold temperatures. I like it, but it should probably come with a warning sign! I'm guessing mine is probably L. texanum simply because I have the idea that it was distributed as 'Coastal Sedum' for a while. The original plant was simply called a sedum when I got it. But I'm not assuming even when distributed as 'Coastal Sedum' that those doing the distribution really knew much about the plant.
