Have you ever stopped in to visit the Otis Douglas Hyde Herbarium here at the Center for Urban Horticulture? This amazing resource is home to over 20,000 plant specimens and focuses on horticulturally significant plants for gardens and landscapes. With specimens dating as far back as 1908, you can view native plant specimens taken from the UW campus from before the campus was even built. Or identify a plant growing in your garden today with the Herbarium’s free plant identification service.
In addition to providing plant identification to the public, the Herbarium serves as a resource to University of Washington students learning about plant identification. Students can compare multiple specimens of the same plant side-by-side to observe finite details between species, something that would be very difficult to do in nature!
Want to support this great resource? Take a little piece of the UW Botanic Gardens home with a one-of-a-kind framed herbarium specimen or stop by the Washington Park Arboretum gift shop for a pressed flower note card handmade by Herbarium volunteers. Speaking of volunteers, the Herbarium has a large and active volunteer community and is always looking for new volunteers.
The Herbarium is run by a part-time Research Assistant and is open 20 hours per week. Check the website for current hours.

Did you know that the Washington Park Arboretum often serves as a research site for researchers at the School of Environmental and Forest Sciences? Recently, researchers at UW have been using the Arboretum to study LiDAR and its applications. LiDAR (Light Detection and Ranging) is a method of airborne laser scanning that can be used as a tool to inventory and manage forests. Below are some of the research papers discussing their findings.

Twenty-five volunteers, agency partners and Rare Care staff gathered in Klickitat County in mid-June to monitor known populations of rare plants in the Klickitat Wildlife Area, Conboy National Wildlife Refuge and surrounding areas. We knew from the outset that our survey plans had to be adjusted. Late wet spring conditions caused as much as a one-month delay in the onset of flowering for many species. We were too early to catch the long-bearded sego lily (Calochortus longebarbatus var. longebarbatus) in bloom. But we caught the tail end of Baker’s linanthus (Leptosiphon bolanderi), a tiny spring annual that normally blooms in April and May. Our timing was perfect for finding Pulsifer’s monkey-flower (Mimulus pulsiferae), another tiny annual found in seasonally moist areas that seemed to have benefited from the spring moisture.
Klickitat County was an ideal location for Rare Care’s fifth annual monitoring weekend. It’s at the east end of the Columbia River Gorge, a region that hosts some of the state’s most diverse flora. The Gorge is one of the few places in the northwest where moist Pacific air meets dry Columbia Basin air near sea level, providing a corridor for migration and a refuge for relict populations from previous glacial and interglacial periods. The Columbia River system also provides a significant corridor for species movement from its headwaters in the Rocky Mountain ecoregion of British Columbia, through the Okanogan highlands, Columbia Basin shrub-steppe, and east Cascades, and out to the wetter ecoregion of the west Cascades. The convergence of these topographic features is likely a major factor in the high number of endemic species found in the vicinity.
Twenty-four surveys were completed over the three-day campout, including new populations of rare plants such as oblong bluecurls (Trichostema oblongum), western ladies-tresses (Spiranthes porrifolia) and common bluecup (Githopsis specularioides). Regional endemics such as Barrett’s penstemon (Penstemon barrettiae), gooseberry-leaved alumroot (Heuchera grossulariifolia var. tenuifolia), and Suksdorf’s lomatium (Lomatium suksdorfii) are locally common on the cliffs and steep slopes of the Klickitat River. We monitored several populations of each and documented several new sites while surveying for other rare plant populations. We also monitored blue-flowered diffuse stickseed (Hackelia diffusa var. diffusa) and the very rare Ames’ milk-vetch (Astragalus pulsiferae var. suksdorfii), found in Washington only from an area around Conboy National Wildlife Refuge.
Although we accomplished so much in the short three days we had, we wrapped up the monitoring weekend with the impression that there is still much ground to cover in the region. We look forward to more explorations in the basalt canyons and pine woodlands in the coming years.

Oral History of Washington Park Arboretum, the Arboretum Foundation and the Center for Urban Horticulture
In 2010, a combined effort of many donors, led by John Wott, funded an oral history project, administered by the Miller Library. Carrie Bowman is supervising the project; Shelly Leavens was hired last November and spent the past ten months conducting research and interviewing people. People with long term associations with the Washington Park Arboretum, the Arboretum Foundation, and/or the Center for Urban Horticulture were invited to participate. Carrie, with the help of many others, looked for narrators who fulfilled multiple roles within these organizations, as well as seeking narrators from outside them.
The collection of interviews is an open door to our history. The intent of this phase of the project was to collect a variety of interviews, index them so that people can determine what was discussed, and organize them so that materials relevant to each interview are gathered in one place. Research materials, field notes, indexes, and narrator data sheets are all included with the interviews. This collection will remain in the Miller Library and will be available for public use. Arboretum Bulletin article.
The public is invited to a presentation of the project on Tuesday, November 1, from 5 – 7 pm in the Miller Library. Several displays will showcase the interview collection and will remain on exhibit in the library from Oct 21 until the week of Nov 20. The displays include audio clips from the interviews, set up so that people can browse at 5-10 different “stations.” Light refreshments will be provided.

The new Cascadia bog is a perfect solution for a wet spot.
When the Cascadia section of the Pacific Connections Garden was under construction, a natural depression appeared. Recognizing the potential for this poorly-draining area, Jason Henry of the Berger Partnership incorporated a Cascadian bog into the design. Pacific Connections Gardener Kyle Henegar explains, “Creating the bog is a long-term process as the soil conditions mature, the plants are phased in, and as Roy Farrow and I continue to procure and stage snags and rocks to create a more realistic-looking garden. I suggest visitors come visit the bog frequently to see how it ages over time and develops the beautiful patina of a native bog.”
An irrigation system will keep the soil soggy during dry months. Vegetation includes Andromeda polifolia, Ledum glandulosum and Rhododendron occidentale grown from seed collected in the Siskiyou Mountains by Collections Manager Randall Hitchin, and Darlingtonia californica from the UW Botany Greenhouse. Native plants such as huckleberry and maidenhair fern are serving as placeholders while bog plants are being phased in. In addition, the Cascadian Focal Forest contains a Siskiyou seep area along the east side of the first stairway. It too is being phased in and is currently full of container-grown native plants and plants grown from wild-collected seed.
