  • The easiest of the Arboretum specimens to find is on the Upper Trail below the Peony bed.

2)  Cupressus goveniana var. pygmaea (Mendocino Cypress)

  • The “pygmy” stature occurs in this tree’s native habitat: infertile ancient sand dunes above the Pacific Ocean near Mendocino. In normal soil, it can exceed 100 feet.
  • The crushed needles smell like lemon peel.
  • It is located on Arboretum Drive near the south end.

3)  Laureliopsis philippiana

  • Native to Chile and Argentina.
  • Crushed leaves smell like orange.
  • It is located in the Pacific Connections Entry Garden and on Arboretum Drive in grid  9-4E.

  • The fragrant, waxy berries were made into candles.
  • Located in 43-B in the Arboretum’s Oak Collection.

5)  Pseudotsuga menziesii (Douglas Fir)

  • For Northwesterners, this is the essential smell of Christmas in the winter and the forest in summer.  It is native to the North American west coast and self-sows freely in the Arboretum.

January 16th, 2013 by Lisa Sanphillippo

UWBG School Programs serve over 6,000 kids a year and we could not possibly do it without the help of our volunteers. We are hiring volunteer Garden Guides now and have two dates to get folks started on their journey to engage kids in the great outdoors.

Saturday February 9th from 11:00 – 3:00 pm and
Saturday February 16th from 11:00 – 3:00 pm

Guides need only attend one training, but are welcome to both. Both trainings will cover an introduction to the University of Washington Botanic Gardens as well as round table and in the field discussions about class management, interpretation techniques and age appropriate teaching.

February 9th we will focus on our Plants 101 and 201 programs and February 16th we’ll focus on Wetlands 101 and 201. New guides will learn what the big ideas of each program are, how the student’s age affects the level and amount of information given and how to use the props and activities in the field.

If you would like to fill nature with children and teach them about plant science, ecology and more, contact Lisa Sanphillippo at 206-543-8801 or lsanphil@uw.edu for more information.

We value our volunteers for their time, experience and dedication! We hold enrichments, training and other educational opportunities regularly. Call or email now to become a treasured part of our team.

“Judge a Plant by Its Cover”:  Twigs and Bark

Photo of Acer buergerianum (Trident Maple)  trunk

1)   Acer buergerianum (Trident Maple) – photo of trunk (to the right)

  • Move over Stewartia pseudocamellia, at least for the time being.
  • Exceptional mottled flakey, lighter gray-brown bark on this young Asian maple.
  • Makes a good street tree in Seattle, tolerant of a wide-range of stress factors.

2)   Acer caesium ssp. giraldii

  • Maple featuring young branches covered with a whitish bloom (DO NOT TOUCH)
  • Native to the Himalaya region of China (Shaanxi and Yunnan provinces)
  • Specimen located along Arboretum Drive in the Peonies

3)   Betula albo-sinensis var. septentrionalis (Chinese Red Birch) – photo of trunk (to the right)

  • “The bark is singularly lovely, being a rich orange-red or orange-brown and peels off in sheets, each no thicker than fine tissue paper, and each successive layer is clothed with a white glaucous bloom.”  – E.H. Wilson, Aristocrats of the Trees
  • Please resist the temptation to tear, pull, rub… the bark.  It is disrespectful, potentially harmful to the tree, and a crime to deface public property.
  • Grove located in the Witt Winter Garden.
Selected cuttings from the Washington Park Arboretum (Jan. 7-17, 2013)

Samples of #2, #4, and #5

4)   Cornus sanguinea   ‘Midwinter Fire’

  • A multi-colored thicket-forming dogwood.
  • Brightens up ones’ spirits on any dark and gloomy winter Seattle day.
  • Located in the twig bed of the Witt Winter Garden.

5)   Prunus maackii   (Manchurian or Goldbark Cherry)

January 2013 Plant Profile: Blechnum chilense

January 8th, 2013 by Soest Gardener, Riz Reyes
Light frosts are tolerable and quite attractive, but very deep freezes can cause damaged fronds

Light frosts are tolerable and quite attractive, but very deep freezes can cause damaged fronds

Once so rare and only available through close-knit garden circles, this exquisite fern can now be purchased from several growers and specialty nurseries.

Our original plant growing here at the Center for Urban Horticulture came from the famed Miller Garden from Elisabeth C. Miller, herself. Over the years it has established into a prolific clump of thick, evergreen fronds that resemble the local name in its native Chile “costilla de vaca”, which literally translates to “cow’s ribs”.

It’s a robust, but slow growing fern compared to others, but it thrives in the same condition with adequate moisture and full to part shade with rich, but well drained soil with a lot of organic matter.

One caveat to this incredible fern is its winter hardiness.  It can easily survive temperatures just below freezing, but a very hard frost will damage the tough fronds and the plant can take its time waking back up from the base. It is best suited in a protected and sheltered location such as a deep woodland or in close proximity to a building or neighboring trees and shrubs.
