A recent example is the replacement of two Japanese maples on the east shoreline. For years, these trees have been suffering in the dense, waterlogged soil along the shore. When seeking to address this issue, rather than try to change the Garden for the plants, we changed the plants for the Garden. In their place, we planted weeping varieties of katsura (Cercidiphyllum japonicum ‘Morioka’), which is adapted to wet conditions and hopefully will thrive in this area. Moreover, the original plans included a half dozen weeping willows (Salix babylonica)—pioneer trees that have almost all been removed. We hope the katsura, though a new addition and adaptation to the collection, will honor this intention. As we get a better handle on how site conditions are changing with time, we also look forward to the increasing availability of plant material that may be better suited both to the physical environment and the aesthetics of our Garden. For example, warmer, drier conditions have made varieties of evergreen oak more popular in the Pacific Northwest. Various evergreen oak species, including Quercus glauca and Q. phillyreoides, are “workhorse” shrubs and small trees in gardens all over Japan and would be a wonderful addition to our Garden. Gardens are never “done.” They are living, active spaces, and their growth and change is part of why they mean so much to us. At the Seattle Japanese Garden, we creatively manage and adapt to that change in order to preserve the original vision of the designers. Here, one can experience a treasure unique to certain gardens: the timelessness of unceasing change. m Pete Putnicki is the head gardener at the Seattle Japanese Garden.
