I've always considered snapdragons to be annuals. But then I realize that often they return the following spring and do just fine. So now, I'm wondering how folks in the PNW care for snaps - do you cut them back in the fall and if so, how hard? I planted a bunch of them this last spring, and find I prefer the small to mid size varieties rather than the rocket series. So, my plan for this fall is to pull out all the tall boys, and somehow encourage the small ones to survive the winter and put on new growth next spring. I note in the database that generic snaps are hardy to zone 7 and I am an 8b. Where they are planted is somewhat exposed (southwest hillside) so I thought I'd mulch with shredded leaves for the winter. Also in this bed are sweet allysum and feverfew, both also pretty hardy for me. Any suggestions are appreciated.
