Hi, I am hoping to get some help identifying these perennials in my garden in Saskatoon. They are in full sun. The 'unknown green' is about 2 feet high and has just started to have the yellow regions. The 'unknown' pink is maybe a cornflower? the plant for the pink flower is about 2 1/2 feet high. It is just finishing blooming. The 'unknown purple' finished blooming a few weeks ago and had small purple flowers on the stalks. Any help naming these would be great. Thanks!
1. Centaurea dealbata 2. Campanula glomerata, just finished blooming. 3. Lady's mantle, Alchemilla mollis. There are other similar-looking species (e.g. A. faraoensis) but A. mollis is commonly-grown and therefore the likely one.
