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.

Plants Profile gives a fairly accurate idea of native range of plants in the US. I find it by typing in the name of whatever plant I want, followed by usda. And notice I said 'fairly,' not 'totally'. Here is a link that might be useful: USDA map for Chamaechrista fasiculata

I looked up Scarlet Flax on Google and that is DEFINITELY the hot pink flower that is growing amongst my wildflowers. Thank you so much for the help IDing it.. I wouldn't have figured it out otherwise. I had researched "pink wildflower with 5 petals" a hundred times in different words, but couldn't find anything accurate. Apparently it's considered red, but to me.. it's hot pink! Also, thank you for help IDing the Calendula.. I thought it might be Calendula (buds and foliage looked familiar), since I do have a few of those in my front gardens.. but the ones in my front yard are only yellow. I wasn't sure they came in orange (with brown centers), too. Last year I bought 6 Calendula seedlings.. they reseeded and now there's about 50 in my front yard!! The one in my original posting must've been from seed, included in one of the wildflower packets I purchased and planted.. since it is a different variety. Wasn't sure it was a wildflower.. Glad to know!! Thank you again for your help.. Always appreciated :)

The last 2 are Clarkia elegans. Third one down is a Poppy of some description. I could guess at the others but there's not much point. Can you repost when you have some flowers? If you want 'wild flowers' in future the best plan is to get seed which is local to your area. Many wild flower mixes are collected and packed in places which have very different flora from the grower's. Seed from Florida would not be a good match for a garden in Canada. Alternatively, forget the 'wild flower' concept and just get packs of hardy annuals. (ie ones that can be direct sown.)
