Yes, I think some sort of Carnation. Carnations root pretty easily from cuttings so why not cut flowers?
You will have to cut the flowers off and recut the bottom. But don't do anything until you have your supplies: pot, soil, rooting hormone, plastic bag with corner cut off to use as a humidty dome, reptile or heat mat. Use a sharp knife, not scissors to cut the bottom as you don't want to damage any of the cell layers in the stem. You should have 3 nodes up and 3 nodes down - that's the ideal but work with what you've got. They will root or rot in 2 or 3 weeks.
