Dianthus

Plant out now in your flower beds. Do not overfeed. Put a little sharp sand or grit around each one. They are hardy but may have been raised in a greenhouse.

Thank-you doctor bob that's a nice little job for tomorrow

or if you are worried pot them into a reasonable sized pot and put in a cold frame/cold greenhouse for the winter.
but if you are planting out drbob is spot on. are you expecting decent weather tomorrow? lucky thing.
