This week’s selections honor the area we call Crabapple Meadow and the residing collections therein.  Each summer, the Meadow becomes home base for our annual summer camp participants and instructors and with this year’s season winding down, we feel it is a good time to recognize a handful of our terrific Malus specimens.
1)   Malus  ‘Sundog’

The “Flowering Crabs” comprise a genus of some 35 species of deciduous trees found throughout northern temperate regions. 

1)   Castanea dentata                                                                    American Chestnut

American Chestnut once dominated many forests from Maine and southern Ontario to Mississippi and from the Atlantic coast to the Appalachian Mountains, and was once one of the most common trees in the northeastern United States.
American Chestnut suffered a catastrophic population collapse due to the chestnut blight, a disease caused by an Asian bark fungus (Cryphonectria parasitica). 

1)     Acer palmatum ‘Nuresagi’                                                     Japanese Maple

Now that the vivid colors of the emerging foliage of Japanese Maples have faded, it is time to appreciate the summer beauty of the sometimes, very colorful samaras (winged achene containing the maple seed).
Not all Japanese Maples produce showy samaras, but some cultivars are known specifically for this.
Acer palmatum ‘Nuresagi’ (“nuresagi” translates to “wet heron”) is located at the edge of the Upper Woodland Garden Pond. 

The peninsula north of the Linden Parking Lot (#16) is sometimes referred to as the Lagoon.  Enjoy these trees while walking, birding, viewing wildlife, or boating.
1)     Nothofagus antarctica                                                 Antarctic Beech

This tree is native to southern Chile and Argentina.
A deciduous tree with shaggy bark and small glossy leaves can be found north of the canoe launch.
It was once believed to be the southernmost growing tree on Earth until 2019, when a Nothofagus betuloides was found on the same island just slightly further south on Hornos Island, Chile. 

Here’s a small peek at a few of the many plants here at the Washington Park Arboretum that are showing off their unique spring features.
1)                 Cercis canadensis                                                   Eastern Redbud

One can’t help but admire this small, often multi-stemmed flowering tree as its glowing, purple-pink buds break out in spring through early summer.
With stunning cultivars such as ‘Appalachian Red’ and ‘Forest Pansy’ being highlighted in botanic gardens and arboreta, popularity has soared over the past several decades. 

The next time you treat yourself to a walk through the inviting grounds of UW Botanic Gardens, take a moment to appreciate that the flowers and trees play an important role in scientific research–with implications for plants and research institutions all over the world.
“We get requests for plant materials from researchers and institutions about 10 times a year,” reports Raymond J. 

If you missed our peak magnolia bloom, you can extend their beauty virtually here enjoying several wonderful photos of a few of my personal favorites.  Many thanks to both Niall Dunne – Arboretum Foundation Communications Manager and Bulletin editor, Ray Larson – UW Botanic Gardens Interim Director and Skylar Lin – PSGO aerial photographer for sharing their extraordinary photos capturing these magnificent magnolias in bloom! 

The mysterious case of X-478*A and B, a.k.a. “Hobbit trees”, continue to baffle and impress those who are familiar with these two unique Arboretum Dawn Redwoods.

1)   Abies bornmuelleriana                                                                Turkish Fir

This species is allied to the Caucasian Fir (A. Nordmanniana), but with some characteristics of the Greek Fir (A. cephalonica), notably the resinous buds and glabrous shoots.
It has a small range in northwestern Asia Minor, where it forms forests on the Bithynian Olympus.
With regards to our collections at the Arboretum, we have a few specimens in the Northwest Pinetum, as well as the one shown here residing below the Pacific Connections New Zealand Garden. 

1)  Leucothoe davisiae                                                                                   Sierra Laurel

This evergreen member of the Heath family is native to the mountains of eastern and northern California where it grows in bogs and seeps.
The hot-pink buds will open in spring to reveal white urn-shaped flowers.
You can find Leucothoe davisiae in the Cascadia Forest.
