Dieringer Nursery Company was established at its current location in 1972 with our origins in the 1940's. We're sited just south of Portland Oregon in the fertile Willamette Valley. We are a wholesale production nursery that specializes in rhododendrons. We supply plants to garden centers,landscape companies, retail stores,other production nurseries and to re-wholesalers.
the principals, Jeff and Greg Dieringer have a combined total of 79 years of rhododendron experience. Our goal is to provide you the healthiest, most gorgeous rhododendrons in North
America.Since our focus is rhododendrons, we've spent a great deal of time trialing varieties and evaluating growing techniques and plant inputs. Therefore we prefer to offer varieties that have proven to us to be good performers in the customers' landscape. With the goal of healthy plants paramount to our company mission, we have been moving our production systems to a sustainable model. Rhododendrons present an interesting challenge when incorporating so called "organic" methods, yet we are making progress with new techniques every year.We invite you to contact us or visit us to share your ideas and experience in this new frontier.
