Caragana arborescens is often recommended as a fast-growing, nitrogen-fixing windbreaker or living snow fence in rural settings. It is often used as a single-row field shelterbelt for borders, screens, or flowering hedges. It is very tolerant of infertile soils, cold winter temperatures, drought conditions, alkaline soils, and deicing salt. It requires little maintenance. Some ethnic groups have used young pods for vegetables. The bark provides a fiber and the leaves yield an azure dye. Its seed is a valuable food for wildlife, particularly gamebirds, and mass or row plantings provide cover for upland game. There are at least five cultivars of Siberian peashrub available in the US for specific landscapes, these include 'Sutherland', Lorbergii', 'Pendula', 'Walker', and 'Nana'.

You would be better to post your comment in the comment section rather than a reply. I still practice some conventional horticulture, especially with annual flowers and indoor plants. Even in conventional ornamental horticulture I take my lead from my old teacher Dr. Michael Dirr, who wrote his huge Manual of Woody Landscape Plants (for eastern North America), who was not enthusiastic about Caragana. For the last 20 years I have been a native plant enthusiast of eastern North America and my great passion is mostly for scenic, naturalistic landscapes with all native plants, which also give the greater amount of food benefits for native insects and birds = better ecology. I am not one of the purist fundamentalists. I just do not want to see any more bringing of any kind of plant from one part of the world to the next, unless it it a food, medicinal, or fiber plant. Everybody has plenty of ornamentals now. In my Midwestern and Eastern USA there is a big problem with quite a number of invasive plants from Eurasia as Amur Honeysuckle, Multiflora Rose, etc. Of course, some Eurasian plants are good, even here. You are in the Western Biome of the US, of which I don't know many plant species. I would recommend you to check out the native plant societies in the West and see a new perspective.
