You will be given a private tour of their test garden, that features many of these cultivars, and many more that have yet to reach the market.

What to expect on Iseli’s tour: The Jean (pronounced John) Iseli Memorial Garden was created in 1986, the year Jean Iseli unexpectedly passed away. Over the years, they have grown a diverse collection of conifers and maples. You will see specimens of rare and unique cultivars, including some that have not yet been released to the public and others that never made it to market and can only be found here. All the plants are listed with a botanical name, and if there is an Iseli triangle, it is an Iseli Introduction. We will start out in the South garden and I will go over some of our signature collections as we tour, as well as discuss information about Iseli Nursery. At the end of tour, you will receive a small plant specimen to take home.

Still a family owned business, J. Frank Schmidt & Sons is known around the world as a premier source of deciduous shade, flowering and ornamental trees. The best of these was Red Sunset® Maple, a tree that put J. Frank Schmidt & Son Co. on the map soon after its introduction in 1966. Named the “Number One Shade Tree” in Ohio Shade Tree Trials, it soon became the top selling red maple in the country. More than 50 years later, it remains a very popular cultivar.

What to expect on J. Frank Schmidt’s tour: The tour will start near their headquarters in Boring,Oregon, with an overview of tree production from seed sowing to sale. The tour will include two locations of their propagation departments, and at one there will be the opportunity to see plants being bench grafted. We will also tour the seedling farm where over 50 miles of seedbed are sown every year. Bare root production fields where 1, 2 & 3 year trees are produced and also our container yard where trees are grown in containers for year round sales.

In the early 80’s, Laura and Tom Dufala started with a small bonsai business. Later, they discovered they preferred growing in-ground pines. Today they grow Pinus resinosa, Pinus thunbergii, and Pinus contorta. Bentwood Tree Farm combines Eastern aesthetics with Northwest farm growing techniques. On the tour, you will learn about pruning techniques of the different pines, and soil characteristics that conifers and pines prefer.
