I think this image is a little better than the ones I took at Nose Hill a few days ago. This one was taken at the Erlton/Roxborough Natural Area. Too bad that they will be pulled in a few days' time - if they aren't pulled, then they spread and take over the area, killing all the native plants. They are quite spectacular, these large Nodding/Musk Thistles, and are my favourite species of Thistle.
