Polychroma is one of my favourite spring plants .........a delicious mound of chrome yellow. I have one in front of a low growing purple berberis and They look stunning together.
Nut if second one spreads it is not polychroma so you are prob correct
griffithii ....drat this iPad I meant to type in Dixter earlier....is a plant I will no longer grow. For me it is invasive. Dixter, apparently, is a clone selected by Christopher Lloyd
