Memories of colour

Winter well and truly returned to Alberta yesterday, bringing an afternoon snowstorm (here in Calgary) along with strong winds. Funny, the snowstorm lasted for maybe two hours (and later snowed during the night) - the very two hours I was out with my camera, trying to photograph some ice formations that a friend had just e-mailed me about, thinking that I might love to go and see them! This morning is overcast again, but hopefully there won't be any more snow? I think most of us are wonderfing if spring will ever arrive - and stay. Took this flower photo at the Reader Rock Garden on 10 August 2011.

Not sure if this is Centaurea dealbata (Persian Cornflower)?
