Silver Rockcress / Smelowskia calycina

Photographed (macro) on Plateau Mountain on July 2nd. There were quite a lot of clusters of these plants and most had all the buds fully opened. Occasionally, you would come across one like this one, with just an outer ring of pretty little white flowers. Love the name of this plant : )

Sorry about all the plant photos at the moment. I have been cropping, etc. so many the last little while, to pass on to local fellow botany people, so I have piles of flower images and not enough time to search for any bird or other type of photos. Our growing season is SO short in Calgary!! Gotta dash to my volunteer shift this afternoon.
