I tidy up mine before winter, then when I see new growth in spring I recut them to remove any winter-kill. When you cut off the parts with seeds you can either sprinkle the seeda about now or save them to WS later.

Mine are biennial. I collect the seeds and sprinkle and re-sow like Trudi suggests. For me, they're over.

For me they have been back after flowering...this is the 2nd year bloom for them, but them I haven't allowed them to set seed. If I did they would otherwise be biennial.

Interesting! Well I cleaned them up and they are green and healthy looking. Very nice actually for this time of year. Now does this mean they will bloom next year again? Or do I just have to wait and see?

After going to seed most likely not.
It would be interesting to know if they still come back tho. When I gave some of my original wintersown seedlings to my neighbor hers did not come back after setting seeds. There are several biennials that can be tricked into behaving as a perennial and there are some plants which depending on the climate can be short lived perennials or biennials.
For me my Sweet William came back bigger and better then the first bloom season...

Although this pic was taken on April 13th, this is exactly how it looked from fall thru winter...
