First Washington Botanical Symposium

First Washington Botanical Symposium

Lewisiopsis tweedyi by Dick Olmsted

An extensive network of professional, academic, and amateur botanists are actively engaged in the conservation, management, and study of Washington’s diverse flora. Their expertise ranges from how best to manage biodiversity, to understanding climate change impacts on plant communities, to naming and classifying the flora’s rare, common, and invasive elements. Invited speakers and poster presentations will share new insights and discoveries about these topics and more. Participants from throughout Washington and adjacent areas will have the opportunity to exchange ideas with colleagues within and across disciplines.

Join us on March 15 for this exciting symposium.

March 2017 Plant Profile: Corokia cotoneaster

Corokia cotoneaster may not be the first plant that you notice in the landscape, but it might be the plant keeps your attention the longest. This plant’s divaricate branching (having branches of wide angles) and its tiny dark evergreen leaves give it a sparse and angular look which is not a common sight among the green gardens in the Pacific Northwest. Add a spring bloom of tiny fragrant yellow flowers followed by red berries in autumn and this plant can be a focal point of any garden. Its common name is wire netting bush which describes the plant’s unique form.

There are several standout specimens of Corokia cotoneaster located in the McVay Courtyard at the Center for Urban Horticulture and many more plants are establishing in the New Zealand section of the Pacific Connections Garden at the Washington Park Arboretum. This plant gets better with age and can be admired throughout the year. It should be in bloom from April to May so be sure to take notice on your next visit.

Read more about this month's featured plant.

Common name: Korokio or Wire Netting Bush

Family: Argophyllaceae

Location: Several plants are on display in the McVay Courtyard at the Center for Urban Horticulture. Numerous specimens can be found throughout the New Zealand Forest’s Mountain and Snow Tussock zones at the Washington Park Arboretum (Grid 7-3E. 8-3E and 9-3E), and in the New Zealand Entry Garden (6-3E and 6-4E)

Origin: New Zealand

Height and spread: 6-8 ft in height and 4-6 feet in width. Cultivar ‘Little Prince’ is smaller, attaining a height of about 4 ft.

Hardiness: Cold hardy to USDA Zone 8


Glimpse into the past - Tree Care Then and Now

Dick Hart using power saw, 2-27-57

Dick Hart, Arboretum crew leader, pruning trees with a power saw, standing in tractor scoop. March 27,1957.

The Arboretum was established in 1934, and tree care has always been a priority. After nearly 80 years, many of our trees are huge. Like the phenomenal growth of the Pacific Northwest trees, professional tree care has grown dramatically in recent decades, advancing from simple saws and ladders to sophisticated training, equipment, specific methods including testing and licensing. Today there are hundreds of professional certified arborists, working under the leadership of the International Society of Arboriculture (ISA).

Take a "Glimpse into the past" with Director Emeritus John Wott, and see pictures of the “creative tree care” given by Arboretum crews in the late 1950s - 1960s. It is a wonder there were not more serious accidents. Today the arborists and crew in the Arboretum all use the latest techniques and equipment.



Attention early childhood educators: Our Fiddleheads Forest School is partnering with Natural Start Alliance to offer training opportunities. Join us for Creating Outdoor Spaces that Encourage Exploration and Discovery, March 24, 9:30am-5pm.

We're currently hiring for someone to join our education team, leading our school age programs. Learn more.

March 28-30 we'll be co-hosting a series of arboriculture trainings in cooperation with the Pacific Northwest Chapter of the International Society of Arboriculture. Learn more.
