July Highlights

Summer is here, and the Arboretum is humming with life! The air is full of floral and resinous scents, the birds are chirping, the bees are flying, and the colorful displays of leaves, flowers, and fruits are many.

There are a lot of different ways to enjoy the Arboretum in summertime for all ages. There are free hikes and tours, classes and workshops, and free youth and family programs to participate in.

Looking to explore the Arboretum on your own? Check out our Plan Your Visit Page, as well as a new blog written by Visitor Information Specialist Greg Hill highlighting some Verdant Ventures.

Trees to See!

California Buckeye

Aesculus californica

This large, deciduous shrub is a member of the soapberry family and is native to California and Southwest Oregon.  Its striking, fragrant white and pink flower spikes, with 80 or so blooms on each stalk, attract various species of butterflies.  Don’t touch!  The seeds, leaves, and sprouts are poisonous but were used by indigenous people (after boiling the plant parts for several days). The nectar is toxic to honeybees, so beekeepers have to be sure this plant is not in their vicinity.

Location: Visitor Center front planting area and on Maple Trail.


American Bladdernut  and European Bladdernut

Staphylea trifolia, Staphylea pinnata

The common name of this large, fast-growing shrub comes from its bladder-shaped seed pods, which contain several large, black seeds. The pods appear after the flowers. The seeds are edible and are said to taste like pistachios. The flowers, which bloom before the plant leafs out, come in drooping, bell-shaped clusters. You’ll see plentiful flowers in years that follow hot summers. The American species likes the warm, wet summers of the Midwest. “Trifolia” refers to the three leaflets composing each leaf.

Location: On Walnut Trail near intersection of Hawthorn Trail

Ichang Papeda

Citrus 'Ichang Papeda'Citrus cavaleriei or Citrus ichangensis

Notice the lemon-scented leaves and, if you’re lucky, a fruit that looks like a pale yellow mandarin but with a much tougher rind. The inside of the fruit is very seedy and contains a small amount of very sour juice. Despite being very hardy, it is seldom cultivated but is used as a stock for grafting more edible citrus species. Since it grows to between 2 and 5 meters high, this native to China is in that in-between size that could make it a shrub or a tree.

Location: Ramp by Visitor Center

Ocean Spray

Holodiscus discolor

This Pacific Northwest native is seen commonly along roadsides and other disturbed soils in the Willamette Valley and throughout Oregon.  Its common names come from the creamy white flowers that resemble sea foam.  The flowers attract butterflies and other beneficial insects. Notice the many fragrant, five-petaled blossoms.  The small fruits that follow the flowers often stay late into the fall since birds don’t like them.  Coastal tribes eat the Holodiscus’ seeds; use its dense, hard wood for arrows and other tools; and use various parts as medicines.
