My favourite Thistle

After a volunteer shift on 23 July 2014, I wasn't too far away from the Erlton/Roxboro Natural Area, where I was finally going to go on a botany walk. Having been to this location several times before, I knew it was a short, easy, flat trail, and that I could go as far as I wanted and then turn back early, which is what I did. I've missed pretty well all the botany and birding walks the last few months, which is quite depressing. The main thing I wanted to see were these Nodding / Musk Thistles, as they are my favourite species of Thistle. They are called a "weed", but I love to see them. The sun was unfortunately in the wrong direction, so I was only able to get a couple of OK shots, but better than nothing. Its name, Nodding Thistle, comes from the fact that the flower heads commonly droop to a 90° to 120° angle from the stem when mature. Here in Alberta, this species is a noxious weed - but a beautiful one.

With a couple of hours to "kill", I had spent them at the Reader Rock Garden, which was just a few minutes' drive away from the evening botany walk location.
