Anne Elliott's photos with the keyword: 25 July 2017

A very quick grab from the archives, as I was beginning to feel the need for some colour in my photostream! I had hoped to make a start on Day 11 of our trip to Ontario and Quebec in May 2018, but I had things to get done today. Tomorrow, I have to go and get a cortisone shot in my left hip, so will need to rest for a couple of days. I was thinking they would do both hips in the same appointment, but I was told they only do one at a tme - which does make sense. Second one will be in about 12 days' time. The shots I had in both knees a few weeks ago had no effect on the pain level, so I am really hoping that tomorrow's shot will have a better result. This is the seedhead of a Nodding Thistle, taken on 25 July 2017. These are my favourite thistles, but unfortunately, it is an invasive species. The Alberta Provincial Designation for Nodding/Musk Thistle is Prohibited Noxious. "A native of Europe, nodding thistle has a long history as a rangeland pest. The invasive nature of this aggressive plant can lead to severe degradation of native grasslands and meadows because grazing animals focus on native vegetation giving the thistles a competitive advantage." From invasiveplants.ab.ca. www.invasiveplants.ab.ca/factsheets/FS-NoddingThistle.pdf en.wikipedia.org/wiki/Carduus_nutans

The large Nodding or Musk Thistle is my favourite species of Thistle. Unfortunately, this quite spectacular and beautiful species is on the list of Restricted, Noxious, and Nuisance Weeds In Alberta. It is a biennial that spreads rapidly by seed forming extremely dense stands, though when I have seen this species growing in several places within the city, there are usually only a few of them. Yesterday, though, I saw how, if left, these Thistles can spread. I finally got out on a botany walk yesterday afternoon, 25 July 2017. The smoke from the British Columbia and Alberta wildfires has cleared, it was a lovely sunny day, and at last the destination was a place to which I could drive. Also, I knew that this would not be a very long walk and it was all on the level. I was hoping that there would at least be a few of these thistles growing. Most of the flowers had died, but I still love those spine-tipped, inner and outer bracts. The flower itself is a beautiful pink/purple. I have added a previously posted photo showing a flower in its prime, in a comment box below. www.botanicalgarden.ubc.ca/potd/2011/08/carduus-nutans.php en.wikipedia.org/wiki/Carduus_nutans This photo was taken at the Erlton/Roxboro Natural Area, not far from downtown Calgary. It is the richest botanical area, for its size, within the city. Over 385 species have been recorded in an area of about three hectares. (All of Fish Creek Provincial Park has only about 460 species). Eighty species, however, are aliens, now occupying 90+% of the area. It is such a shame to see how the area is being devastated by plants that include Baby's Breath, Creeping Thistle, Yellow Clematis and other invasive species.
