Polygonatum yunnanense
14th May 2017
A small growing plant. The Polygonatum 'OG.904974' has recently been identified as the same species however I think this is a different clone, there seem to be several in cultivation.
The species was separated from the variability of P. nodosum by Aaron Floden in 2012.
