Coenosium Gardens – A Conifer Laboratory!
Bob Fincham has a worldwide reputation as an conifer expert, with a list of introductions and publications to his name of which any plantsman would be proud. Coenosium Gardens, the 5.6 acre property that he and his wife, Dianne, have developed in Eatonville, WA over the last few decades, is a virtual laboratory of conifer grafting, breeding and experimentation. Their website explains that that they focus on plant introductions and that they are the ‘go to’ site for those wanting to locate rare conifers, read articles about conifers or just generally find out what is going on in the conifer world.
When Form and Foliage made the pilgrimage to Coenosium in September, we found all that we had been expecting…and more. What the articles and the Fincham website don’t convey is what a beautiful spot the couple has created, by having an eye for color, shape and texture combined with deft plant combinations. The word ‘Coenosium’ comes from ancient Greek and means ‘plant community’. Plant community, indeed! A virtual wonderland of the principles that F&F holds dear: interesting plant material, combined to enhance the attributes of each plant, not detract from them, planted with regard to the shapes and sizes so that each plant can do its part and not get lost in a shapeless mass.
Bob and Dianne run a successful mail-order nursery from their home, but the majority of the acreage is given over to expertly landscaped plantings, with a focus on pleasing combinations of foliage. Deciduous trees and shrubs (especially beeches and maples) are interplanted with the beloved conifers to provide contrast of both color and texture.
Our visit coincided with peak fall color, but the huge variety of plant specimens at Coenosium guarantees a show at any time of year. As the photo above illustrates, conifers come in many different shapes, sizes, colors and textures.
The grounds range from more mature plantings around the house to newer gardens that focus more on dwarf varieties. Bob has written a book about dwarf conifers, entitled ‘Small Conifers for Small Gardens’, that is a must-read for anyone wanting to learn more about incorporating conifers into the home garden.
Many of the gardens have an Asian feel, with plants such as Ginkgos and pines that are associated with Asian gardens and statuary and hardscape distinctly Asian in design. The dwarf Ginkgo above is suitable for even the smallest gardens, and contrasts beautifully with its conifer cousins.
Bob has made somewhat of a specialty of gold-foliage conifers, perhaps because the Seattle area is known for its share of overcast winter days. The sunny foliage of the spruce in the photo above shines like a beacon even when the sun is nowhere to be seen. It also contrasts beautifully with the maroon and blue foliage in the background.
Bob also uses conifers in containers – a practice that those with small gardens (or even those limited to terrace gardening) can adopt. Many of the dwarf and miniature varieties are so slow-growing that they can exist happily for years in containers, sometimes even sharing space with others.
Bob and Dianne’s mail order nursery is the place to go to find rare varieties and a good selection of garden-worthy dwarfs and miniatures. Their stock is healthy and well-cared for and we confess to falling victim to the wide array of choices available and picking out a boxful for shipping. Needless to say, the plants arrived in perfect condition.
Finally, the following photos show that the ‘mad scientist’ is at work in the ‘laboratory’! Bob is continually fascinated with what he can do using his grafting skills and his imagination. Whether the gardening world is ready for some of his creations remains to be seen, but no one can accuse him of not pushing the envelope!

Incredible display of conifers- makes me want to rip out and plant them!!

Sue we know you have a gorgeous garden and we wouldn’t want you to rip out a thing. But a few miniature conifers nestled amongst your plants might be just the ticket!

Evergreens…so fresh and green and Washington to me….I learn something new everyday I have never seen a 2 color conifer..and I would have deadheaded the lighter green hahahahaah…grafting is an amazing art
It sure is – and Bob Fincham is a master! Thanks, Sharon.

There is so much new and exciting in the conifer world it really draws you in. Michigan never looked like this!
I bet if you looked for interesting conifers in Michigan now, you’d find them! They’re everywhere… Jan and Sara

I really like the container with two conifers, the short needles and long needles are a great contrast!

There is an amazing degree of contrast in color, shape, texture and size amongst conifers! Add to that ease of care and year-round appeal and you can see why we love them!
I love escaping to your site!! Fabulous as always. What variety is the ginko, and the pot with the two conifers, which variety is the lower one? They are so beautiful.
Thanks, Jan! We didn’t note the particular plant names as we toured, so were limited to what we could remember when we got home!The Ginkgo was one of the many dwarf varieties (and I have a two-part series on dwarf Ginkgos in the next two Conifer Quarterlies) – perhaps ‘Mariken’, which is one of the best. It would be perfect for your garden if you don’t already have one. There are a couple of shots with multiple plants in containers, and again, we focused on the concept, not the particular plant.
