Karen... Thanks for sharing the information. I've seen pics of some new ones out that look like they have frosted plumes. I was drooling.
I have so many critters and wild birds here, that if I put something out to try and winter sow, they come and eat my seeds. The one year, I tried a couple of containers outside for winter sowing and one was over turned. I picked it up thinking it was a squirrel that had knocked it over and had me a birdie instead. : )
