Yes, cotoneaster hedge at 36" height. I have also 85 linear feet of lilac, which is my favourite in the spring. Be careful to plant the non spreading type. These are 11' tall along the side property lines. They spread to about 4'-6' in width so they take a lot of space, . I have a lot of 11' tall caraganas as well, but they really are more invasive....but an old saying about a high fence means good neighbours....True.

great response thank you! planning a "natural fence" for the backyard but seems like not a lot of options at zone 3a
