Q.Wormwood zoning areas
I live in northern Minnesota and want silver mound as a ground cover. My conditions are not the best. My property is rocky and clay. Can I still grow it and will it survive?
I think silver mound stands a pretty good shot of growing and surviving if you amend your clay soil. Here are some articles that will tell you how:

Silver mound is rated for zones 3-9, you are zone 4 so you are within the acceptable range.
