I remember one conventional nursery selling some in the 1980's in the Chicago, Illinois area, but I have not seen this species native to Siberia, Mongolia, and northern China hardly at all. It is not really a great ornamental shrub anyway. I don't see any purpose in it being in North America. Unfortunately, it has escaped cultivation in areas in Canada and the USA, especially out in the West, and it is listed as a noxious weed in some Midwestern states. The weeping cultivar is sold by few conventional nurseries still, including Monrovia, the huge company of nurseries along the West Coast. Once again, it is not a good ornamental and would be best to not continue it.
