Dear Adam et al, This is an interesting species. According to the best I can find, this species is endemic to Upper Burma and like all ssp of L. aurea sub- tropical in growth demands. In my experience and understanding all L. aurea are extremely frost tender and if the winter green foliage (which is the most succulent in the genus) is exposed to even light freezes it will collapse and bloom is compromised. I think that anyone growing a plant with this label and in your Zonel has a misidentified plant. Your " L. a surgens" could be any of various yellow flowered species - the most likely is of course L. chinensis, or L. longituba var flava or a hybrid of these two. The true L. aurea has the remains of its leaf bases still prominent at the base of the scape. Leaves produced in autumn. Leaves are the largest of any species over 2 feet long, 1 inch wide and distinctly succulent. Does this fit your plant? Few people are able to bloom the true species north of Zone 8 or 9.
