Red osier is used quite a bit in landscapes. You should be able to buy it at most large garden centers. The main landscape appeal for red osier is the red stems in the winter. After about 3 years of growing the red stems turn a grayish brown color so you cut the shrub back to about 6" in the spring(or selective pruning) and let the new, red shoots sprout. You have to give these shoots at least 2 years before they are ready to be made into arrows but with a few plants and a good thinning method you can have arrow shoots every year.
Another good shoot arrow plant you can buy at a garden center is arrow wood viburnum(Viburnum dentatum). Both should grow well if planted according to planting instructions and in an appropriate area of exposure.
