I really want to grow both of these again.

==>>>hmmm.... just harvest the seed ????

i dont know the IDs.. but if they came in a wildflower mix.. they must come true form seed... so why would you need the name to go buy the seed ... follow me???

The first one is a sweet pea.

It's always a bad idea for me to post before finishing my first cup of coffee in the am, but I'll go for clarkia for the pink one...C. elegans, perhaps?

Could the pink one be stock, aka Matthiola?

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.

Ken,
If I like a plant even if growing it and can save seeds from it, I want to know what it is. When plants do well for me, l want to look for more of it in other colors or relatives of it The Lathrus odoratus (Sweet Pea) for example comes in lots of other colors. If I don't know it is a Sweet Pea, how can I possible acquire more varieties?

Another reason to know the identity of your plants: you don't want to start collecting seed and sowing same seed of a plant that will likely become a villain in your garden.

It's also nice to know if the seeds will grow true or not.

Sweet Pea, Lathyrus odoratus, is the vine.
Bottom two double pink flowers are Clarkia elegans, not Verbena bonariensis.
