My Taraxacum albidum is looking good at the moment!
The seed for this came from the Scottish Rock Gardening Club seed list 2016/17 (SRGC3660) and I planted two plants here. However, they look different in that the leaf shape is different (T. albidum is described as having deeply indented leaves) and only one has hairy scapes (as T. albidum). I suspect some crossing has been going on. 
T albidum is itself a hybrid between white flowered Taraxacum coreanum and Taraxacum japonicum.
