Early in June I received an exciting message from the Arboretum’s School Age Programs Coordinator, Cait McHugh. Cait had a request: she’d like to send us the weekly themes for UW Botanic Gardens summer programs for pre-kindergarten, grades 1-3, and grades 4-6 and have librarians select and send a weekly care package of books to enrich their curriculum. Instructors would borrow the books about a week before the start of a new themed program, giving them time for lesson planning.Read more

An evergreen hydrangea?!! You betcha!
There are very few evergreen vines for gardeners in the Pacific Northwest, but this gorgeous gem from Asia is becoming more readily available and it’s simply one of the coolest flowers you’ll ever get to witness opening.
From plump, peony-like buds, they begin to slowly crack open, a froth of fertile flowers begin to form and over the course of a few days, a flat umbel “lacecap” begins to form.
When visiting the Washington Park Arboretum on a regular basis, it is usually not evident that changes occur in both the plants themselves as well as the land forms. However it is easy to see when you compare the photographs over a period of years. This is particularly true when there is water movement involved.
This summer, there will be a new garden constructed near the large southern-most pond along Azalea Way.
This month, instead of profiling a plant, we’ll be profiling a completely different kind of organism… slime molds!
In the fall of 2015, the Elisabeth C. Miller Library at the Center for Urban Horticulture held an art exhibit about slime molds: Now You See It, the Slime Mold Revelation! I had never head of these organisms and was intrigued by the art display and the amazing enlarged photographs of their fruiting bodies.
