Meconopsis Racemosa

This is quite an amazing blue poppy. We have grown these, experimentally, on a dry, south-facing bank whereupon, before flowering in midsummer, they seemed to die. What a surprise we had the following spring when the sleeping tubers magically re-appeared and flowered away with prickly stemmed, jagged-petalled, deepest blue flowers. Not at all what you expect from a meconopsis!
