What are some berry producing plants, attractive to bluebirds, whose fruit lasts through the winter?
Among the best are the American holly, Mountain ash, Staghorn sumac, pyracantha, bittersweet, red choke berry, and various hawthorns. Multiflora rose is also one of the best, but this shrub can become a serious nuisance because of its invasive nature. There are many books available that deal with landscaping for wildlife. Plant species native to your area will insure a hearty and long lasting yield year after year. Your local nursery may be able to help if he is accustomed to plantings for attracting wildlife. Check with your state forester, game commission, or local natural resource district to see if they have any publications on this subject.
