Nova

I’ve noticed several plants, ‘Nova’ and ‘Prairie Moon’ among them, show more yellow coloration in cooler climates than here in the Midwest. Even my mlokosewitschii could hardly be described as yellow.  The foliage shows its macrophylla heritage.  Formerly named Olga. Silvia Saunders commented it “sets seeds well”.

‘Nova’ used to be carried by several nurseries, but at least one has recently discontinued this cultivar.
