They like fun sun but may well do fine in part sun. If you planted them this year then next year they should bloom for you. They will reseed and build a clump for you if you don't do much mulching around them and keep the soil loose.

Ok I just reread your question and I got a bit confused. That happens to me quite a bit sorry. If you were given a blooming carnation plant this year then it is at the end of it's life span so it has to reseed or you will loose the plant. It takes carnations forever to form seeds. They are formed in the bottom part of the blossom where the stem widens below the petals. It takes over a month, or at least mine did. When the seeds are viable they are black.
