ROFL yes each parcel of land has it's micro climates. I'm on a hill that runs to a river. THe air moves up hill and then down hill, and generally during the day I get hay in my mouth( if I don't keep it shut) when I toss hay to the horses in a particular paddock---Arielle
I'm afraid you are correct, but . . . I checked on the temps for this nursery in Washington state--my home state BTW--and see that the average lowest temps in the winter are in the 40s. Here's a link to that information:

Remember that SOME nurseries have plants drop-shipped from another nursery. That may be the case here, or you could call them and discuss your particular climate with them. I'd opt for a more cold hardy Mulberry variety, but DON'T give up hope until there is NO HOPE. LOL. The micro-climates on my acre baffle me all the time. Why does one bush do well on one side of the acre and not on the other? Why are there hot spots? Cold spots? And the most baffling--something I call "no spots."

In generall I do think the climate is become more extreme: colder winter days and hotter summer days here. So I am ok with getting cuttings off a local tree that thrives a few miles away.
A few years ago, the local hospital was expanding, yet again, and this time it was to increase the parking lot size. I was so sad to see HUGE 30 foot mulberries come down. Must have been 4 of them. I thought it ironic, here was a food tree being destroyed by a hospital that is supposed to aid people. I still think of those trees when I go to that lot, which is rarely. We are very short sighted.
