Safer Digs For Osprey Now In Union Bay Natural Area

June 12th, 2015 by UWBG Horticulturist

An Osprey nesting pole was installed yesterday in Union Bay Natural Area (UBNA). Located near Carp pond in the SE corner of UBNA loop trail. UW Athletic Dept funded the project when it was realized Osprey were being attracted to nesting in ball fields’ lighting across the way. Hopefully now, people will be safe from falling branches and Osprey will have more appropriate digs to settle into.

Jim Kaiser, consulting wildlife biologist and owner of Osprey Solutions, was hired to do the install. Jim has installed over 300 Osprey nesting poles in the PNW. He is one of the most knowledgeable biologists on Osprey and has quite a fascinating and experienced repertoire in creating new homes for them.

Glimpse into the past – the Legend of the Flamingos and the Silver Egg

June 4th, 2015 by Jessica Farmer, Adult Education Supervisor

By John A. Wott, Director Emeritus

This month’s Glimpse is about the ‘Legend of the Flamingos and the Silver Egg’ featured at the recent celebration honoring Dr. Harold B. Tukey, Jr., and the founding of the Center for Urban Horticulture.  Dr. Tukey arrived in Seattle in May 1980 and one year later, several new faculty and staff were added.

During that time period, the American public had been ‘poking fun’ at the profusion of inexpensive (rather cheap) plastic ornaments which had been flooding our marketplaces.   The urban landscape took on a new look with its plastic balls, animals, statues, pet rocks, etc.  It was inevitable that a symbol from that urban environment should be chosen for the fledgling CUH.

The two first graduate students in the program, Sharon Buck and Cindy Maitland, decided that a pair of pink flamingos should be part of the CUH display and proudly presented them to Dr. Tukey on May 31, 1981, as members of the CUH Alumni Association.  The faculty and staff were excited and decided to hold a naming contest, voting by secret ballot, with the names of ‘Xylem’ and ‘Phloem’ chosen.  The following holiday season, and in subsequent seasons, the proud ‘parents’ were joined by a large silver egg in a CUH courtyard display.

The presentation of a pair of flamingos occurred for each new faculty and staff member hired, often appearing spontaneously on their front lawn or porch.   I was given a pair which I proudly named ‘Burt’ and ‘Ethel’, who proudly presided on my deck overlooking Lake Union.  Flamingos often appeared in many ways during the next few years around CUH.  In 1994, six appeared on my new home lawn, causing the neighbors to wonder about their new neighbor.

Today, flamingos come in many assorted colors and themes, including Husky mascot colors.   While reminiscing with Dr. Tukey at the Celebration, he remarked how much we were all full of the new doctrine for urban horticulture in the 1980’s, but the addition of the plastic flamingos brought us back to our relevancy to the urban environment.   Recently two of my new neighbors have been officially “Flocked” through a legitimate business.  While ‘Xylem’ and ‘Phloem’ have long disintegrated, their prototypes live on.

Selected cuttings from the Washington Park Arboretum (May 11-24, 2015)

Selected cuttings from the Washington Park Arboretum (May 11-24, 2015)

1)  Cytisus x praecox ’Luteus’           Warminster Broom

  • This broom is a hybrid of C. multiflorus and C. purgans and is located on Arboretum Drive in the Legume Collection.
  • Many of the brooms are blooming now or soon to bloom, including the pineapple broom, Argyrocytisus battandieri, whose fragrance earned it its common name.

2)  Erica arborea var. alpina           Tree Heath

  • While non-alpine tree heath can reach heights in excess of 20 feet, the alpine variety is the “short” one, reaching only 10 to 15 feet.
  • Alpine tree heath has white flowers versus light-gray, and the scent is reminiscent of honey.

3)  Hydrangea luteovenosa           Sweet Hydrangea

  • In full bloom now, this semi-trailing Hydrangea is located on the Ridgetop Trail in Rhododendron Glen.
  • Though widely distributed in western Japan, this species of Hydrangea is critically endangered in Korea.

4)  Rhododendron ‘Snow Lady’ x Rhododendron degronianum ssp yakushimanum

  • Hybrids are often created to blend two or more outstanding traits from two separate taxa into one single plant, e.g. flower color and leaf indumentum.
  • There are several areas in the Washington Park Arboretum, including Azalea Way, Loderi Valley, Rhododendron Glen and the Puget Sound Rhododendron Hybridizers bed, showcasing many hundreds of hybrids of Rhododendron.

5)  Syringa reflexa           Nodding Lilac

  • The buds of Syringa reflexa start out a rosy–red before opening to pink and eventually fading to almost white.
  • The specific epithet “reflexa” refers to the nodding habit of the flower heads.
  • Lilacs are located throughout the Washington Park Arboretum, though many are found just south of the Woodland Garden along Azalea Way.

Restoration and Renewal in the Goodfellow Grove

May 11th, 2015 by Rosemary Baker

Salmonberry (Rubus spectabilis) and white western redbud (Cercis occidentalis alba) in April bloom

It’s spring and time for a full on revival in the Center for Urban Horticulture’s Goodfellow Grove!  Dedicated to the late Marilou Goodfellow, the Grove was designed to demonstrate the use of native plants in a transitional landscape and is aptly located between the formal ornamental gardens in and around the Center for Urban Horticulture and the “wilderness” of the Union Bay Natural Area.

As a former UW Botanic Gardens graduate student, a botanist and restoration ecologist, and landscape designer specializing in native plants with horticultural appeal, I am thankful for the opportunity as the new gardener assigned to the grove.

We are working on re-defining original beds and pathways, taming and radically renovating shrubs and trees, and will be installing beautiful true native/native cultivar wildflowers and groundcovers for the upcoming summer events season.  If you see me, ask me about wild foraging – there are some native edibles in the grove and even the weeds are delicious…

May Dispatch from the Forest Grove

May 7th, 2015 by Kit Harrington


      Who doesn’t love spring? It’s the earth’s bright green answer to winter’s dreary grey; when all the world begins to grow anew. If autumn is a time for introductions and winter for exploration, then spring is the season for culmination. In autumn we ground the students in the important, fundamental lessons of the forest grove: clearly identifying the boundaries (both figurative and literal) of the classroom; teaching an awareness of self, social expectations, and emotional responses; guiding newfound interest in the natural world. Throughout the winter we build on these lessons through experiential learning, and when spring comes they have already taken root. So now it is May and already we’ve begun encountering the result of all this preparation—new tendrils of independence, exploration, and self-direction emerging from a solid foundation of confidence and respect. The children know what their needs are and they know how to get those needs met.


     Confidence and self-control empowers the students to engage with the environment in new ways and overcome unexpected challenges. When the tree nest was accidentally dismantled, the children approached it as an opportunity and not a setback and have worked on it as a team almost every day during the weeks since. And now that the kids are adept at managing transitions, we get to spend more time exploring the surrounding area in small groups and taking short “field trips.” Currently, we are making a point of getting down to the garden at least once a week with the help of our wonderful interns and volunteers, but we look forward to adding in a story time or two at the library come June and possibly even a trip to the Center for Urban Horticulture. When Sarah and I left to speak at the BGCI Education Congress the children felt excited to have Joanna, Kate, and Alicia in the classroom and were able to continue to learn and engage and not feel overwhelmed at the change in teachers. From an adult perspective, these steps may seem small, but in early childhood they are huge accomplishments, reflective of many months of hard work and cooperation. The underlying self-regulatory skills that propel these achievements will play a crucial role in the success of both graduating and returning students next year as they encounter new peer groups and personal challenges.


     Cognitively, the preschoolers in both classes are at point where they are considering the lessons in a more abstract way, making connections between ideas and experiences and considering the implications of what they are learning. Over the past few months we have begun gently encouraging the children to strive to engage in more extended exploration and study on a particular topic, and to stay regulated and attentive throughout circle. In addition to being empowering, this level of concentration and control is allows the students to gain a deeper understanding of the topics we are learning about.

Learning to associate numeral and quantity with reptile countingOur natural science theme this year is “vertebrates” and the students are enjoying connecting their lessons at circle with their experiences in the field. We moved from mammals to birds and over the past two weeks began studying reptiles and more recently, amphibians. The children learned that reptiles are cold-blooded, lay leathery-shelled eggs, and have scales. We discussed and read books about common reptiles including snakes, lizards, and turtles. A number of the children built their own reptiles from the bones up, adding scales to cover the body and using materials from the forest floor to make a nest. A “Reptiles of Washington State” matching work provided fodder for discussion and gave children the opportunity to match pictures as well as words. A sensory tub with sand, eggs, and reptiles became a center for socialization and imaginative play. At circle time the children learned silly and informative songs about turtles and boa constrictors. A walk to the Azalea Way pond allowed for some first hand experience with reptiles here at the arboretum. Upon our return from the Education Congress the children shared their delight at discovering two painted turtles swimming around a large koi fish! We hope to return there soon for more discoveries.

     Last week our wonderful stand-in teachers Joanna and Kate introduced our new amphibians unit. The children listened to stories about amphibians and enjoyed a new amphibian sensory tub with water. Over the next week and a half we will continue to learn about amphibians and their life cycles and contrast their characteristics with those of reptiles. We will keep our eyes peeled for salamanders both in the water and out and are hoping that we can find some chorus frog tadpoles to examine as well. In addition we will be further exploring camouflage among amphibians and reptiles and do some experiments to help us better understand why clean water is essential to the life of a healthy frog.


     Another new material in the forest grove is the beautiful scrapbook Joanna started last week with the help of the children. Since then drawing pictures of our classroom and areas we visit around the arboretum has become a hugely popular, collaborative effort. It is a wonderful way for the children to reflect and remember and it helps us grown-ups better understand how the students perceive their world. We look forward to continuing this project throughout the rest of the school year and in the coming years as well, and see it as an important tool for documenting the learning that goes on up in the forest grove.


     When Sarah and I returned from St. Louis we brought with us a new book, the aptly named How to Find Flower Fairies by Cicely May Barker. We chose to introduce it because of the creative way the authors use the pop-up book format to encourage children to peer into, under, and around objects in their environment. It immediately became an incentive for engaging with the environment in precise, very thoughtful ways. In small groups, the children enjoy discussing their own perspective on fairies and whether they are real, and these conversations provide an opportunity to practice listening to and respecting different opinions.


     “Are fairies real?” is a common question in the forest grove, and more than just encouraging imaginative play it has provided the children with a basis for using scientific principles to develop hypotheses, gather evidence and arrive at conclusions. We encourage the students to explore and experiment and come to their own conclusions, and the group is about equally split on where they stand in this regard. Too often in early childhood education we try to inhibit debate among young children, but Sarah and I believe it is impossible to teach conflict resolution without allowing the students to practice differences of opinion. When children freely express their own opinions and are encouraged to consider other’s, they develop a sense of self while simultaneously building empathy. Whether or not they “believe,” the process of searching for, discussing, and constructing elaborate new dwellings for these imaginary creatures wherever we go is enthralling. It is the shared journey, the tiny discoveries, and the potential of the unknown that lie at the heart of this experience and make it so compelling. Both Sarah and I consider the experience of magic during childhood as a provision for the grown-up conviction that anything is possible, and so it is wonderful to watch our little fairy scientists questioning and engaging with the natural world.


    Over the next few months there is still much more to do, more to learn, more to explore. We will finish our vertebrates theme by studying fish before moving on to an in-depth study of wetlands and habitats here at the arboretum. The garden will continue to play a central role in our natural science curriculum. Students will study plant life cycles, learn about native plants and noxious weeds, and come to understand the role of different insects on plant health. We will take our time learning and make sure to follow the children’s lead whenever possible. The depth of their learning is so much greater when they guide the process themselves.


     As an educator, I try to take the time to step back and just observe when I can. When the opportunity arises I will sit back on my heels for a moment and watch the kids at work; hands digging in the dirt, eyes peering intently into the undergrowth, lips curled into a faint smile. From this vantage point, it is clear that the past two years of learning and living in the forest grove have culminated in a group of children who are capable and empowered to do anything they set their minds to. At moments like these, I am absolutely certain that it is going to be an absolutely wonderful spring.

Tune in next time for more news of Fiddleheads and the Forest Grove….

All the best,

Kit and Sarah
