Blue is the colour.

OK, name that football team?

Was down the Botanics visiting my usual haunts and it seems that colour other than blossom is returning to the gardens. Nearly got caught out with a shower, hence the droplets, but my knowledge of the layout of the RBGE helped finding a wee shelter in the bushes till it passed. The flower is a Meconopsis ‘Slieve Donald’ or a Himalayan Blue Poppy, this being an early example.
