I had always heard of Luther Burbank and also the Santa Rosa plum but never put two and two together. When we moved up to Sonoma County, we visited the Luther Burbank home and gardens and learned how much he contributed to agriculture and hybrid plants. He was persistent and worked very hard to achieve his excellent results. The gardens are lovely and many of the plants he developed are in the well-kept gardens. The docent tour is excellent although a little long. But you will learn a great deal and will enjoy the tour much more. This is a special place we love to take visitors. It is HIGHLY recommended!!
