Welcome Jim
Are you referring to plant with foliage that's Plum-ish in color? It looks familiar but I can't quite place a name with it. Sorry. The flowers are an interesting color and shape, though!
Maybe one of the Sedum albums. I grow S. album Coral Carpet and S. album Murale. Both have plumish foliage and white flowers. but there are many Sedum album cultivars so it is hard to say. And there may be other sedums that produce white flowers. I am hardly an expert at sedums.
