UW Botanic Gardens Spring Break and Summer Camps

February 19th, 2013 by Sarah Heller, Community Programs Coordinator & Fiddleheads Forest School Director

It’s that time of year again when we pull out our calendars and begin to think about summer plans. Consider signing your child up to play and learn outside all summer! We are offering seven weeks of outdoor, nature-based summer camps at the Washington Park Arboretum. New themes have been added like Wetland Rangers and Northwest Naturalists, and kept some of our favorites like Woodland Wonders and Art in the Park.

We are also offering a spring break camp in conjunction with the Seattle Public Schools spring break week. What better way to spend a week in April than exploring our 230 acres of natural wonderland in the heart of Seattle? Spring break is supposed to be a *break* so we plan to play games, go on hikes and adventures through the nooks and crannies of the Arboretum, and tackle projects like building a fort, creating Andy Goldsworthy inspired art and exploring the uses of our native plants.

UBNA hosts creatures of all sizes…urban wildlife never ceases to amaze!

February 10th, 2013 by Rosemary Baker, UBNA RA

 

A surprising UBNA find - a western redback salamander (Plethedon vehiculum)

A surprising UBNA find – a western redback salamander (Plethedon vehiculum)

Amphibians are the canary in the mineshaft, warning-systems for deteriorating ecosystems and yet this species was found in the former-landfill, Union Bay Natural Area, in January 2013.  Nestled beneath woody debris and in hibernation mode, it was accidentally discovered by a volunteer during a work party to remove Himalayan blackberry.  Why isn’t this one “red-backed”, you ask?  That’s because although most commonly having an orangey-red dorsal stripe, this species occasionally presents a yellow one instead.

What a great find!

What’s new in Union Bay Natural Area for 2013, you ask?

February 10th, 2013 by Rosemary Baker, UBNA RA

Greetings! I’m excited and grateful to be the 2013 UBNA graduate student manager for winter and spring quarters. I will be leading volunteer groups maintaining restoration sites throughout the natural area and this season we have begun an internship program with students from Edmonds Community College!

The interns and I are working every Tuesday and Thursday through early June, so if you have any interest in getting dirty, releasing some pent up aggression on the proper objects (weeds!), and basking in the beauty of urban nature, we’re happy to have individual folks join us.  Or if you have a group and wish to arrange for a volunteer work party please contact UBNA manager, Dr. Kern Ewing. His contact info can be found through the University of Washington staff directory.

NW Flower & Garden Show – Get a Jump on Spring

February 7th, 2013 by Arboretum Education Supervisor, Patrick Mulligan

Please stop by the UWBG booth and say “hello” at the Northwest Flower & Garden Show this year. We’ve got a great corner spot at booth #2304 in the Community Organizations area. New for this year, we’re combining forces with Seattle Parks & Recreation to create a “mega-booth” connected by a wedding arbor being built by the city’s carpenter crew. During the show, we’ll be highlighting our Rental Program, so look for lots of pretty pictures of events at our rental sites at the Center for Urban Horticulture and the Graham Visitors Center.

Witch Hazels are in bloom

February 4th, 2013 by Catherine Nelson, Adult Tours Program Assistant

Hamamelis There are several species of Witch Hazel, genus Hamamelis, featured in the Witt Winter Garden, which is in all its glory this month. The colors range from yellow to orange to red and their scent is incredibly heady.
The plant’s common name comes from the Old English word “Wych” which means “pliable”. The pliable branches of this plant were used for water dowsing, which was a way to find underground water, hence this activity also is known as ‘water witching”.
The Witch Hazel and many other winter blooming plants are featured on the Free Weekend Walks held each Sunday at 1:00 pm.
