Like many Minnesota gardeners, a part of me is secretly rooting for climate change. It’s not that I want the ice caps to melt or the East Coast to go under water, but the thought of USDA Zone 5 plants is enticing. It would be wonderful to be able to grow Japanese maples, lavender, KnockOut® roses, and my personal lust plant, butterfly bush, without having to cross your fingers and hope for a warm winter. The last few winters, while snowy and definitely brisk, haven’t seemed that cold. Last January, the lowest temperature recorded in Northfield (according to Weatherunderground.com) was -18, which just barely slides us into USDA Zone 5.
According to the local radio station, it was around -30 here last night, which is more like zone 3. So, alas, we are not zone 5.
My fingers are crossed for the butterfly bush planted in the front garden.
