Tell us a bit about the location of your garden.
We are in a unique location in the outer archipelago, which is in Zone 4-5. I've managed to get a number of unusual plants to overwinter despite the harsh winter climate, including a Magnolia stellata (star magnolia), which I cherish dearly. It probably survived because I laid out the big flowerbed in an old heap of stones. The stones hold the heat in the spring and the autumn, thus extending the growing season.
