Two degrees at 9am. Clear blue skies with mist in the hollows and a jaunty breeze.

The last couple of days, Carmine has been awash with that smell. It arrives on the breeze on special days in mid-winter. It's the smell of things starting to grow. It's a pre-echo of springtime. It's as if a tall woman in North Africa has shaken out a rich azure-coloured rug and the smell of warm sunshine has wafted all the way here.

And as if by magic, a mass of tiny, nameless blue flowers has suddenly appeared.

Anyone know what they're called?
