Perhaps the first picture is Convolvulus arvensis, field bindweed, or Calystegia sepium, hedge bindweed. There is a great website for wildflowers in Minnesota...have you checked it? I wish we had one so extensive for Alaska. I may be using it, though, as many of the plants are the same, or at least could get me to the correct genus. You can do an advanced search which will get you closer than just looking at pictures, as you will know detail that we can't see in your photos.

A friend of mine advised that the secret to getting the Gaillardia 'Oranges and Lemons' to overwinter is to NOT deadhead it. The seedheads are attractive. This is my first year with it, so will have to report next spring, success or failure. I really like Precure Nursery - they offer a number of native plants, like the Baptisia and Pearly Everlasting I got. I always get my Rue and Fennel there because they have nice, big plants, oftentimes with Black Swallowtail cats as a bonus. My all time fave nursery, tho, was Warren's. I got my Passiflora 'Lavender Lady' from them and it is still going strong. Other natives I have gotten from Wild Things when they go to various Farmer's Markets. She sells tons of them, rare ones you would never find at a commercial nursery. But, that is over for this year. Check out their website. She always brings caterpillars of various butterflies, too, eating their larval host plants. The kids, in particular, love it! I have purchased numerous plants from her over the years, including my False Nettle (Boehmeria cylindrica) that is a host for the Red Admiral butterfly. I loved Satterlee's, too, but they were pretty expensive on a lot of their plants. Horn's is a little less expensive. I was sad to see them close the doors on Satterlee's. I stood outside and watered for 4 hours yesterday until 12:45. Thought I would pass out, tho drinking lots of water. Had to do it since I have been at my daughter's for the past week and things needed attention. Susan

One of my garden club friends and neighbors has a loquat tree growing, flowering and fruiting on the east side of her house with about the same exposure you have. She and her husband are gone all summer, so this gets no supplemental watering and does fantastic! I haven't had luck yet duplicating the location, but I've already scouted where I'll buy my tree: Bob Wells Nursery in Lindale. While I don't see loquats on his web site, he has these trees in two greenhouses that are lovely and good prices! I also see from his online store that he also has blood oranges - I wasn't looking at citrus, though the greenhouse smelled lovely. I've been there in person, picked up some berries and fruit trees (pluots and a chocolate persimmon) and am very pleased with the selection!

Between the two you mention, it should be easy to tell apart. Comfrey has larger leaves, is fuzzy, but bristly and not soft. Buds are pink/lavender, opening to blue/purple. False gromwell has smaller leaves, I don't recall if they are fuzzy or not. Flowers are white/green and perhaps with a slight pink/lavender tinge. This is a wild prairie plant, and often grows with only one stalk.
