I am from Minnesota. Does anyone have any recommendations for perennial plants that do well in this area (Zone 4), are relatively easy/cheap to establish, and are multifunctional (e.g. edible, provide mulch material, attract beneficial insects, etc.)?
I have a small urban lot that I garden in vegetables that I am looking to incorporate with an outer ring of perennial plants, to act as a visual and physical buffer. My hope is to have perennial plantings that reduce nutrient runoff, attract beneficial insects, create compostable biomass/mulch, are edible, and are pretty to boot.
Thanks in advance!
