The birthday of naturalist and plant breeder Luther Burbank (1849-1926) is observed in California in much the same way Arbor Day is observed in other states—that is, with activities promoting the value of natural resources and the protection of trees and birds. Burbank moved from his native Massachusetts to Santa Rosa, California, in 1875 and spent the rest of his life there experimenting with new varieties of fruits, flowers, and vegetables. On March 7, a birthday and Arbor Day celebration is held at the Luther Burbank Home and Gardens. Discuss
