I purchased a 3 gallon plant labeled Saxifraga cv. hybrid SAXIFRAGACEAE from a botanical garden. Label said "ornamental deciduous tree w/ lite green foliage that turns bright orange in the fall. Prefers sun, tolerates clay loan. Not easily transplanted." I've searched the web, but alas no reference! Any ideas on what this plant's botannical name might be so I can learn more about it??? Or has anyone had any experience with this tree?
