Sweet William (Petunia)
Purchased early this year from my local nursery I planted my few Sweet Williams in a ready made bed for a display in the coming summer. Sadly up to now there is not one blossom; in fact, they have multiplied and are looking very healthy I must say. It's the end of season almost, so do I dig them up and sling them or what?

If they truly are a petunia, then the season is lost and you should just throw them out. I suspect the location had too much nitrogen as this would cause lots of growth with little flowering.
There is another type of plant called Sweet William that is a type of Dianthus. This plant is a biannual and if what you planted were these, you should leave them in the ground and give them some bone meal to help them with blooming next year.
