The blue in the 1st pic is centaura cyanus aka annual bachelor button. The tall yet to bloom appears to be cosmos bipinnatus aka annual cosmos. The red vine is lathyrus odoratus an annual sweet pea. The last pic appears to be verbena bonariensis hanging out over the side. You can indeed collect seed from these. Some of them will automatically reseed themselves if had been ground planted.

Thanks for all the IDs so far! It is very helpful. To sum up so far - 1) Hypericum perforatum - St John's Wort 2) Trifolium arvense - Rabbit's foot clover 3) Circaea lutetiana, enchanter's nightshade 4) Epilobium species - not sure which species but it does look a little like Epilobium roseum? 5) Pseudognaphalium obtusifolium, rabbit tobacco 6) ??? don't think this is Bidens pilosa, it doesn't have white flowers, just those ugly yellow ones that always look closed. I added another photo for #6, which shows a better picture of the foliage - also this plant grew 3-4 feet tall 7) ??? don't think it's Lepidium campestre, foliage is different - I will try to take a closer pic of flowers 8) Erigeron species - note this one is blooming now, very late in season? Vine is definitely Lonicera japonica! Thanks! That is an invasive, prohibited plant in my state and it is definitely going to be eradicated.

The orange lily is an Asiatic Daylily. They are common in gardens and have escaped all over the northeast US. They don't spread by seed. Instead you could just dig up a few plants making sure to get the root which is a tuber. The second plant looks like Queen Anne's Lace. The flowers will turn brown at which point you can cut the flower head and shake out lots of seeds. This is easy to grow, and in fact is probably srouting in your garden already. THe first year the plants grow a bit like a dandelion but with very lacy leaves. They flower in their second year of growth. The third is in the pea and bean (legume) family. I am not sure what species it is. The smaller yellow ones were probably Birdsfoot trefoil, which is an agricultural crop similar to alfalfa or clover that commonly escapes to grow wild. The vine sounds like a Morning Glory. There are many wild species. Jerusalem Artichoke is a wild sunflower and could be the plant you see. Ther are other similar species of wild sunflower too. I think all are great garden plants. They will spread so give them some room, but they are easy to grow and flower from July thru September. If you are searching for info on a plant, try a search enginer like Google. Go to Google.com and enter the name of the plant. You'll get thousands of pages for almost any plant as long as it is spelled correctly.

It is a beautiful wildflower! The color is stunning and it's a good thing that hubby doesn't mind turning around for closer looks! I have been wandering in the wilderness again. I have three reasons for this, I'm getting some zen time which I need, choosing next year's new garden flowers and training for Heart Walk Dallas. I work in an office behind a computer all day and need to get in some semblance of shape before the walk on Sept 12. The flowers are a nice perk :-) Thanks to you all, Pam
