In my garden I have Seascape day neutral. They're very tasty.

I don't do anything to get them through the winter. I've actually never heard of anyone who has to do anything :)

i'll second seascape

ours are in raised beds on top of double weed-mat,
so we can lose some seascape if we get very cold without a snow-pack

but we also have an alpine-type that survives everything,
it has small berries, but the best sweet/strawberry flavor

Very Interesting !

I had been thinking about Seascape, but Norse Farms had it rated as zones 4 to 9. Based on both of your zones, I'd be good with Seascape as 1 of my choices.

I know people around our place cover them with straw through the winter.

i forgot to mention our fort laramie strawberries are coming back strong this year,
and are full of flowers
