Lathyrus latifolius is a clambering vine with winged stems -- you should have no trouble IDing it from the stem wings alone, if that's what this plant is. But I still think it's lespedeza, and maybe a form of L. thunbergii given the plant size. This species has been a popular garden subject for a long timem and I seem to recollect reading that it was popular in Victorian gardens. There are some nice named varieties available. Check out 'Gibraltar', 'Spring Grove', 'Pink Fountain', 'Little Buddy' and 'Samindare' -- maybe your plant is close to one of these.

Spurge is Euphorbia, right? They ooze milky sap that is an irritant. I would doubt they can be rooted as easily as the succulent sedums, but I've never tried. Both plants look best in poor soil, excess nutrition leads to weaker stems and leaves that lack the characteristic colorations.

Wow check this out, it's a recent local introduction, no wonder none of us knew it! The pic I took was at Meleb. Kinda scary, I saw a LOT of it in pastures and hayfields. (full article link below) "Red bartsia (Odontites serotina) is a weed of hayland, pastures and roadsides which appeared in the Interlake region of Manitoba in the 1950s (Figure 2). The weed apparently was introduced into the area in crates which were shipped from West Germany into the Canadian Armed Forces Base at Gimli. The infestation started on the base and spread into surrounding farmland by way of mowed hay from red bartsia infested areas along the edges of runways. Today the main area of infestation (Figure 1) is in the eastern Interlake particularly in the triangle formed by Gimli, Fraserwood and Meleb. New infestations have recently been found in the Souris and Carman areas. Isolated patches have also been found near Stonewall, Selkirk and Winnipeg. Description and Life Cycle Red bartsia germinates in late spring. At first it grows slowly and may not be noticed during early summer (Figure 3). In July, the weed begins rapid growth, reaching heights of 15 to 30 cm (6 to 12 inches). Stems are erect, branching and bear clasping narrow leaves about three cm (1.25 inches) in length. The leaves occur in pairs and taper to a point. Both the leaves and the stem are densely hairy. Spike-like clusters of flowers develop on flower stalks which grow from the point where the leaves join the stem. Most flowers are found on the top half of the stem. The blossoms are reddish-purple in colour and resemble tiny snapdragon flowers (one cm or less than a ½ inch long). At maturity, an infestation gives a reddish tingle to hayfields, pastures or ditches. This reddish tinge is also seen in infestations of red samphire (Salicornia), a plant frequently found growing in ditches and often confused with red bartsia. The two species can be distinguished by the absence of any leaves on red samphire. Red bartsia is prolific, producing about 1400 seeds per plant. The seed shells out in September, infesting fields for some time to come. Coarse hairs cover the seeds, enabling them to adhere to clothing and equipment. The seed is light and is easily carried along ditches and through fields by runoff water...." Thanks for your detective work anyway gals. Here is a link that might be useful: Red Bartsia in Manitoba

I agree, Corydalis incisa. Very pretty but very, very weedy. I've been trying to rid myself of it for years.
