Carnations are biennials they only live for two years. The first year is foliage the second year is the flower and then they self seed and start the process over again. Although you can start them inside once they can be planted outside they should be so that they can reseed and complete their cycle. So I would say plant half this year and half next year to get a good clump going. They prefer not to be mulched from what I've read although I have read that some people do.

Foxglove does not like to be transplanted so you need to put them where they are going to grow. And then they develop a root system that creates plants in other locations. Again this is a biennial first year foliage and second year flower. If you try to keep it in a container I don't think you'll have it comming up a third year. But I've never tried it.

English Daisy and Lupine I don't know.

Of your wildflower mix Poppies don't transplant well. Snapdragons are considered a tender perennial and only live one year in most locations and should be treated as an annual. Cosmo create a rhysome I think and then procreate that way as well as by seed.

My suggestion would be to make a germination table of all the seeds that you have and keep them until the appropriate time to start them and then do it that way. Many flowers need 4 seasons to do well. Most plants that do well inside are tropicals that need constant warm temperatures. Most seeds will remain viable for many years. There are exceptions but as you research the germination information for each one you will also find out that information.

Good luck with your garden.
