1)   Sequoia sempervirens  ‘Henderson Blue’                        Coast Redwood

Coast Redwood typically has forest green needles, though cultivars range from frog-belly green to silver and powder blue.
This Winter Garden specimen is pruned regularly to keep it dense and short to best show off its beautiful foliage.
Sequoia sempervirens is native to the foggy northern California coast and is currently listed as endangered due to logging and habitat loss. 

We added an interesting specimen this year as a foundation tree in the newly renovated Soest Herbaceous Display Garden bed 3. Our Bronze Loquat was grown from seed that was wild collected by Dan Hinckley at higher elevation in the mountains of Taiwan. We received a sapling from Dan in 2014 and have grown it to larger size in our nursery before planting earlier this year.

Bonsai literally means “tray gardening” or defined as the Japanese art of growing and training miniature trees in pots. These selections are reminiscent of the bonsai art form, although they were never grown in pots nor trained. Enjoy the photos!
1)   Larix decidua                                                                            European Larch

The larches are unusual conifers in that they are deciduous and drop all their leaves each autumn. 

1) Acer palmatum ‘Beni otaki’                            Red Bamboo / ‘Beni otaki’ Japanese Maple

The Red Bamboo or ‘Beni otaki’ Japanese Maple is a medium-sized Japanese maple, with deep red-purple foliage from spring to summer, which becomes green with maturity.
Autumn leaves turn a rich crimson.
Acer palmatum ‘Beni otake’ grows into a lovely rounded shape and is more tolerant of sun than most other Japanese maples. 

When Fall Out Boy sang,

“We’re going down, down in an earlier round

And sugar, we’re going down swinging,”

they were actually referring to leaves falling in autumn and the wonderful process of tapping sugar maple trees for syrup (not really, but wouldn’t it be funny).

Fall has arrived at the Washington Park Arboretum and fantastic colors are here to welcome you! Come by and see the beautiful collections transition into winter dormancy.
1)   Hamamelis x intermedia ‘Diane’                                        Witch-hazel

This is an Asian hybrid Witch-hazel.
The stunning colors of this small tree bring moments of summer during the cloudy fall days.
This witch-hazel and others can be found on the north side of the Witt Winter Garden. 

With the drought still hanging around, these drought-tolerant species are not ready to drop their foliage and are standing tall.
1)   Viburnum tinus ‘Purpureum’

Native to the Mediterranean region.
With blue/purple berries and white/pink flowers and purple foliage, this is a beautiful shrub for interest in October. Great resource for pollinators.
Many found along the Arboretum Loop Trail (A.L.T) on the west side in the Viburnum Collection. 

I’ve been touting crape myrtle as Seattle’s “tree of the future” for years now. And, because of climate change, I daresay, the future is now! Lagerstroemia indica is a beautiful tree for all seasons; outstanding in flower, fall color and winter bark interest.

The Cascadia Focal Forest at the south end of the Arboretum is part of the Pacific Connections Garden. This forest showcases plants from the Siskiyous Mountains in southern Oregon and northern California. Many Indigenous groups (including the Shasta, Yurok, Grande Ronde, and Siletz) have roots in this area. Most of these groups were forced from their historical ranges. Despite the injustices and violence these groups endured, they continue to live in the vicinity and carry essential knowledge about the local flora. 

1)  Castanea crenata                                                                      Japanese Chestnut

Though it is one of the smaller species of chestnut, C. crenata is still a valued food tree in its native Japan. Ordinarily, the nuts are also smaller than those of the European varieties.
This specimen is located on the east side of our old field nursery along the gravel path.

2)  Cephalotaxus harringtonia var. nana                                  Dwarf Plum Yew

Native to the forest understories of East Asia, this small evergreen shrub is known to thrive in semi-shaded places rather than in full sunshine.
