Well, after some more research, I've made some progress on identifying the weeds, and figured I'd share... I'm almost positive #1 is Virginia Buttonweed I think #2 might be nutsedge. Can someone confirm that? As far as #3 goes, I think it is bermuda grass. But I think I actually have some bermuda and crabgrass, particularly where the lawn meets the street. And now begins the long process of trying to revive my lawn. My current plan is... 1. Try to control the weeds as best I can for now by spraying them with weed control for lawns and/or picking them by hand. Already started and it seems to be slowly killing the weeds and leaving the grass intact. 2. Come early-September, I'm going to fill in some depressed areas of the lawn with topsoil 3. Top dress the rest of the lawn with a thin layer of top soil. 4. Add some milorganite (unless someone has a better suggestion) 5. Seed entire yard with tall fescue, or maybe a mix of tall fescue and kentucky bluegrass 6. Water daily until grass starts to grow, then only twice a week for a few weeks, then only once a week. 7. Pray that tons of grass grows and chokes out the weeds 8. Come early spring, spread pre-emergent herbicide on the lawn Thoughts? This post was edited by ryanhaub on Sun, Aug 4, 13 at 0:40

Honestly, I'd try anything here (I live about 20 min's north of Richmond, VA). Our biggest rose problems are powdery mildew on things like dorothy perkins/7 sisters, black spot, and japanese beetles. I've grown New Dawn, Zepherine Doughin, lady banks, Red Fairy, Veilchenblu, Rose-Marie Viaud, 7 sisters, Dorothy Perkins, rosa rugosa, baby faurex, moss rose, tea roses, and austins... I've had decent luck with most. The worst were the DP/7 sis with the PM and the fact that they grew to kingdom come with all those prickles. If nothing else, just take a bunch of cuttings to bring with you wrapped in damp paper & root them here. Good luck!

brit5467, I lived in Mathews when I saw one in Va. I also lived in Glouchester, Yorktown, Williamsburg, Hampton, Lightfoot. I lived in Va a long time, originally from there. Anyway, he came back yesterday, morning and late afternoon. I am going to try to get a better picture to post. Thanks again everyone for the ID.

This is a common annual weed in late spring here in NH as well, almost always in sandy or gravely areas such as road verges and gravel drives. It can occur in large swaths, often tinting the entire side of the road lavender, which is why I first noticed it. From what I see on the USDA plants database, Floral , you are correct; it looks like some type of Nuttallanthus. For me it would be N. canadensis, but for nmushka, it could be N. canadensis or N. texanus.
