This is such a pretty wildflower - I love the ring of tiny green hearts. Several of these Lily-like flowers grow on a tall stem. Photographed on a walk at Brown-Lowery Provincial Park, SW of Calgary on 16 July 2013. Didn't realize just how blurry the image is, ha.

"White camas (Anticlea elegans) is a native perennial herb that grows from a bulb. The plant can be found across most of Canada from British Columbia to New Brunswick and in parts of northwestern Canada. The plant contains several steroidal alkaloids, including zygacine, which can poison livestock and humans. White camas has caused poisoning in sheep and may have been involved in poisoning cattle. Ingesting the bulbs can also cause poisoning. This plant is considered to be about seven times less toxic that death camas (Zigadenus venenosus)."

"It is not a grass (though its leaves are grass-like), but belongs to the trillium family, Melanthiaceae. It has white lily-like flowers and two-pronged, greenish-yellow glands on each petal (the shape of which can help in distinguishing it from other members of the genus)." From Wikipedia.
