This last one is listed as Persicaria 'Lance Corporal' though it is related to the others and I'm not sure what they're decided on for the official name - Persicaria or Tovara. I've seen all of them listed under either name. This has the chevron like 'Painter's Palette'. It seems to take a little more sun, but I keep it in a shady spot and keep in confined to just a couple of plants because this one, unlike the others, is invasive, extremely so, and I had a rather large patch of it before I realized it was just a bit too much. It is a pretty plant, though, and I won't get rid of it all together. The leaf color can vary from green through chartreuse, to almost gold, depending on the light conditions.
All of these bloom in the fall and have a slender bloom scape which rises above the plant and has red flowers, pinhead sized, which run along the scape. Quite unusual and pretty. Tomorrow I'll do the other Persicarias, which I tend to call Persicarias (rather than Tovaras) and keep separate (at least in my head) from these because they have a different flower.
