RE: Siberian Pea Tree
caragana is a tough bush that grows about 12 -15 feet high. It will tolerate tough ND winters, drought, grasshoppers, and catches a lot of snow.
I have some on my yard that my grandfather planted and I am guessing they are nearly 75 years old or older and still going strong.
I can not say that deer prefer them, but they offer a great deal of shelter and cover.
