Helleborus

This is a perfect Michigan Perennial that will provide interest when everything is frozen. Hellebores come in an incredible range of colors and forms, with new variety each year. They’re the kind of perennial that shows up when the garden is asleep. If you’ve never had winter flowers before, this is the plant that makes you stop and stare.
In Michigan (Zones 4a–6b), hellebores are reliably hardy, especially Helleborus × hybridus, with a little winter protection in the coldest, windiest yards.
