Thanks, I have that Dahlia (thanks for the spelling correction btw) photo as a wallpaper on my laptop.
Here's another couple (okay three):
Same Iris as first one, only a more close-up (love the water droplets on these flowers; makes for some unique flower photography)
Canadian Anenome
I don't really know what flower this is, but my gut tells me its probably Chicory. Don't quote me on it though, I've been wrong before.
BTW, it was raining when I was taking these photos...and most of the flowers, except for the first one, are taken in front of the famous Rutherford House on the U of Alberta campus.
