Growing native in Siberia and north-eastern China, this species is the most commonly used in Finland in garden hedges, ranking with the hawthorn Crataegus grayana. Its branches are softer and easier to trim than those of the hard and thorny hawthorn and the clippings make excellent compost. Its use has decreased, however, because of the tendency to mildew on cut hedges, which turns the leaves grey. The hardy Siberian pea tree is suitable for open sunny dry areas, where it grows into a large beautifully flowering shrub, much better looking than as a cut hedge.
