Arbutus unedo specimens can be found surrounding the courtyard on the south side of the Graham Visitors Center.
As the fruit requires 12 months to ripen, both flowers and ripe fruit are present in the fall for an excellent display as well as food for both pollinators and other wildlife.
Varied thrush visit our courtyard in the winter to take advantage of the dense cover and fruit.
2) Berberis x media
‘Arthur Menzies’ Hybrid Barberry
This cultivar of a cross of two barberries (B. lomariifolia x B. bealei) was selected and introduced by the Washington Park Arboretum after it survived a very cold winter in 1962.
This iconic plant of the Arboretum can be found throughout the park.
As with other Berberis x media cultivars, ‘Arthur Menzies’ provides our Anna’s hummingbird with nectar from late fall into early spring.
3) Ilex opaca ‘Emily’ American Holly
Native to central and eastern United States, the female of the species produces abundant crimson (occasionally orange or yellow) berries. A male tree is required for pollination.
Several excellent specimens are located in the central meadow of the Pacific Connections Gardens.
The dense evergreen foliage provides shelter for birds and the fruit is eaten by many small song birds, including robins and waxwings. The American Holly is also the larval host for Henry’s elfin butterfly.
4) Malus ‘Adirondack’ Crabapple
This crabapple cultivar was selected by Donald Egolf at the National Arboretum for its disease resistance in the Pacific Northwest.
A very fine specimen is located on the east side of the Graham Visitors Center.
This upright-growing, compact tree provides food for fruit eating birds such as woodpeckers. The foliage provides material for leaf-cutting mason bees.
5) Morella californica (syn Myrica californica) California Wax Myrtle
This is an easy-to-grow, deep-green, fine-textured shrub that is native to the west coast from southern California into Canada.
Specimens can be found along Arboretum Drive in Rhododendron Glen.
The California wax myrtle attracts the myrtle warbler, kingbirds, flickers, thrush, mockingbirds and is the larval host for the red-banded hairstreak butterfly.
