Your 2nd weed appears to me to be Stellaria media, which we call common chickweed. It would be easier for me to tell if I saw a pic of it growing, rather than already pulled. It could be another Stellaria, or one of it's look alikes.

Something in the Solanaceae family, I would think. Compare to Physalis virginiana. Here is a link that might be useful: Physalis

Charlene, I think you have a pretty good window to get that seed down. The grass seed includes some warm season varieties like grama and buffalo, if I recall correctly, and they won't germinate until it is warm enough. But I'd say go for it, you've keep them nice and cold so I wouldn't worry. The wildflowers might not show until next year, but that'll give em time to develop a root system. Good luck! Sounds nice!

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!
