The challenge in our region is excessive winter wet. Snow can remain on the plants for months. Winter snow is often interspersed with rain, making for multiple layers of snow and ice, resulting in a pancaking of plants. Summers are also damper than most other regions of North America. To grow these plants in our region, well-drained soil is a must. Providing the right site, the plants suggested will do very well in our region despite our excess moisture. These are all relatively long-lived plants and will not get out of control.
