Freezin' Does Sweet William return in Alaska? I have never had it do so in Anchorage? I was amazed however to see that some stuff will self-seed if dropped in the right places. Things that we normally think of as annuals. Lobelia for one. But in most places I spread preen to try to keep the dratted chickweed down so that also inhibits seeds I would love to let grow. That is why I don't broadcast my poppy seeds but sow in pots in the spring. Then transplant into the garden. They don't like to grow that way but it works fine.
