November Color Appears at the Washington Park Arboretum

November 16th, 2012 by Pat Chinn-Sloan

Selected cuttings from the Washington Park Arboretum for November 12-25, 2012

1)   Callicarpa sp.      Beautyberry

  • When the late autumn landscape seems to offer little in the way of vibrant color, the upright shrub, Callicarpa shows us that it has some local Husky pride.  Grown mainly for their clusters of small, bead-like fruit, the Callicarpa species are ideal for a colorful shrub border.
  • Native primarily to China, Japan, and Korea, Callicarpa is a member of the plant family, Verbenaceae.
  • This specimen can be found in our field nursery near Arboretum Drive.

2)   Decaisnea insignis        Dead Man’s Fingers

  • An interesting deciduous shrub within the family Lardizabalaceae, Decaisnea certainly gets noticed when it bears its dullish blue fruit.
  • Native to Western China.
  • This specimen can be seen from Arboretum Drive, just west of the Peonies Collection.

3)   Euonymus myrianthus

  • The fruits of this upright shrub are yellow, but their full beauty is only attained when they ripen and split, exposing the seeds which become orange-scarlet in December.
  • Known commonly as Spindle trees, Euonymus are members of the family, Celastraceae.
  • Native to Western China.

4)   Pieris japonica   ‘Crispa’

  • Evergreen shrub native to the Himalayas, East Asia, North America and the West Indies.
  • Can be found in the Rhododendron Glen.

5)   Zanthoxylum piperitum       Japan Pepper

  • Spiny, tree-like shrub with spherical red fruit.
  • Located in the Rutaceae Collection, near the current pedestrian detour trail.

Seasonal Horticulture Update: “The Summer of Our Content”

November 3rd, 2012 by UWBG Horticulturist

Hydrangea by Harpa KarinUWBG Horticulture and Plant Records staff had a very busy, productive and satisfying summer. A cold wet June and early July pushed extraordinary plant growth, and, oh my, the WEEDS…Then, just as quickly as we could say, “No summer in Seattle”, the heavens went dry and lo and behold, we experienced an historic dry spell extending our summer to October 12. See King 5 news story starring, horticulturist and new plant care team member, Neal Bonham.

http://www.king5.com/news/local/If-today-stays-rain-free-driest-August-on-record-168165016.html

In hindsite, this weather pattern was just what the plant doctors ordered. A prosperous longer than usual planting window followed by a longer than usual dry period enabled us to plant into late June and then complete several landscaping projects into October.

For example, the contractor hired for constructing our 2.5 acre New Zealand eco-geographic display in the Pacific Connections Garden lucked out big time grading the steep, fortunately dry glacial-till slopes with heavy equipment. On a smaller scale, we were able to sneak a new berm in the hollies, which will eventually accommodate new specimens in the American clade. If you visit, check out the new interpretive signage.

It was all about NAIOP’s 22nd annual community enhancement project on the other side of the water at CUH. Early on in the planning stages, our associate director, Fred Hoyt, kept saying this event could be a game-changer for us. As time wore on and the project scope was scaled-back, it began to seem his prognostication would not come to pass. Now, after all is mostly said and done, if not a game-changer, it was most certainly HUGE for much needed improvements and indeed a springboard for potential future projects on our CUH campus, gardens and UBNA that will be appreciated by all for years to come.

I’m particularly excited about the huge effort that went into upgrading our plant production and corps yard area behind DRC. It’s amazing what laying down new gravel and paint can do for a tired looking nursery and storage space. And, just in the nick of time, we will now be able to overwinter lots of plants in a completely restored hoop-house.

Time now to blow the horn, as I would be remiss as a supervisor by not extending praise to my hard-working dedicated staff. Everyone contributed greatly to the enormous summer’s contents worth of planning, preparing, implementing and, of course, maintaining the grounds, gardens and plant records, including all the volunteer programs we’re involved with, throughout our botanic gardens. Here are a few of our summer accomplishments, not previously mentioned, and in no particular order:

  • A newly installed Winter Garden drainage system in the recently renovated SE quadrant. This was a joint operation between UWBG and City Parks crews. Implemented due to waterlogged soils not foreseen in the original bed renovation. May all our efforts pay off for healthy Winter Garden displays in the future!
  • A complete unabridged inventory and review of our plant collections within the Japanese Garden. Believe it or not, this is the first inventory taken since the UW gave up managment of the Japanese Garden to Seattle City Parks and Rec in 1981!
  • The Soest lawn has been renovated. Long overdue. You shoulda seen the thatch pile!
  • The incredible planning and installation for the “Music of Trees”!  Last weekend before UWBG arborist, Chris Watson, and the artist, Abby Aresty, begin the tedious task of dismantling the complex engineered designs.
  • Forest ridge middle-trail restoration in WPA. An Eagle Scout project and another joint operation between UWBG and City Parks staff.
  • Brubaker Quaking Aspen Grove maintenance project. Ask arborist assistant, Darrin Hedberg, where to find it.
  • Another successful and fun “Day of Caring”! Joint operations between all three arboretum partners: AF, UWBG and City Parks.
  • Completion of our 4th year of our 5 year DOE Garden Loosestrife grant. Although we are making headway, there are big challenges that lay ahead for this noxious weed.

And now that it is indeed officially fall and a surprising colorful one at that, it’s onward marching soldiers to another ambitious fall/winter planting season…Coming attractions include continuing McVay courtyard renovation and a Capstone REN project in the hollies to name a few.

Happy Holidays blog readers! Stay warm and cozy and renew your gardening senses by visiting UWBG!

Autumn is at its peak

October 26th, 2012 by Catherine Nelson, Adult Tours Program Assistant

 

The Japanese maple collection in the arboretum boasts more than 90 different cultivars, many of which have been new plantings in the last few years.  This makes our collection one of the largest in the United States.  The Woodland Garden garden itself contains over 70 of these cultivars and the next couple of weeks is the time to see them in all their blazing glory.  The tree pictured is Acer palmatum, cultivar Osakazuki which is at the NE pathway into the Woodland Garden.  This photo does not do the vibrant red leaves justice, but this cultivar is considered to have the most intense crimson color of any of the maples.  It is a hardy grower which does not get much above 8′ tall even in extreme old age and has been listed in catalogs since the mid-1800s.

 

The name Osakazuki is a reference to its leaves which cup at the base, the literal translation is “saki-cup-like leaf.”

Please join one of our free weekend walks over the next couple weeks and view the amazing fall colors.   All tours meet at 1:00 pm, Sundays at the Graham Visitors Center.

October 16th, 2012 by Pat Chinn-Sloan

Selected cuttings from the Washington Park Arboretum (10/8/12 - 10/21/12)

1)   Cotoneaster conspicuus

  • This showy member of the rose family is native to Tibet.
  • Like most other specimens of the genus Cotoneaster, C. conspicuus has an equally stunning, early summer display of white flowers.
  • C. conspicuus can be viewed along the north border of the Graham Visitor Center parking lot.

2)   Ilex verticillata ‘Winter Red’      Black Alder, Winterberry

  • Native to eastern North America, winterberry is an important winter food source for wildlife including raccoon, red squirrel, wood duck and ruffed grouse.
  • The cultivar ‘Winter Red’ produces intensely red berries that can last until spring.
  • I.v. ‘Winter Red’ can be seen just to the north of the Overlook Pond on Azalea Way.

3)   Pyracantha rogersiana ‘Flava’     Firethorn

  • Many firethorns are grown for their showy berries in fall, which can range from lemon-yellow to scarlet.
  • Pyracantha has traditionally been used as a decorative ornamental, as a pollen source for bees and for home security due to their vicious thorns.
  • Several firethorn species and cultivars can be seen along Arboretum Drive just south of the Graham Visitor Center.

4)   Sorbus cashmiriana       Kashmir Rowan

  • Native to the western Himalayas, this rowan bears corymbs of white flowers in late spring followed by pink-tinged white pommes.
  • Our Sorbus Collection is located on the east side of Arboretum Drive between Crabapple Meadow and our giant sequoia grove.

5)   Viburnum sp.

  • This Viburnum, which was collected in China, has yet to be identified to a species.
  • The tiny, brilliant red berries are unusual to the genus.
  • This Viburnum is located along Azalea Way near our Fraxinus (True Ash) Collection.

Looking for Autumn Color

October 13th, 2012 by Catherine Nelson, Adult Tours Program Assistant

I walked through the arboretum this week looking for early fall color in the park. This Fothergilla major always seems to be one of our first color transformations and its brilliant  reds and oranges drew me to it as usual.

The Fothergilla major is a deciduous shrub native to the Southeastern U.S. where its common name is Witch Alder. Though not an alder, it is in the Hamamelidaceae family and, like its relative Witch Hazel, is a wonderful deciduous shrub for any garden.

Although the Japanese Maples are not quite turning as of this date, there is still great fall color to be seen in other trees like the Chestnut,Maples, Sumacs and others.
Our Free Weekend Walk topic from mid-October through at least mid-November will be on fall color.  Come on a tour and let us show you the Park in its autumn glory. Join us on any Sunday at 1pm in front of the Graham Visitors Center.

Fiddlehead Fridays – New Sessions!

October 9th, 2012 by Community Programs Coordinator

Our Fiddlehead Thursday Fall Series filled so fast I could barely keep up! As the wait lists started to grow we decided to add a second set to our fall series. Now the same programs are offered every other Thursday AND Friday. Here’s what’s coming up:

October 18 – Falling Changing LeavesFULL
October 19 – Falling Changing Leaves, 9-11am
Everything is changing as we move from summer to fall. How can we tell and what is happening? Falling leaves, changing colors, and shifting wildlife patterns will clue us into the signs of fall.

November 1 – BatsFULL
November 2 – Bats, 9-11am
Bats move through the forest at night using only sound while they hunt for insects. What’s it like to be a bat?

November 15 – Where do the Birds Go?FULL
November 16 – Where do the Birds Go?, 9-11am
Some birds stay, some birds fly south. Why? We will learn about why birds migrate and discover which birds are here to stay for winter.

December 6 – CamouflageFULL
December 7 – Camouflage, 9-11am
How come we rarely see the coyotes living in Seattle or the millions of insects tucked around our green spaces? Camouflage is the ticket to staying hidden. We’ll discover different forms of camouflage and see how well we can camouflage ourselves!

IMLS grant funds geo-referenced, integrated database

October 8th, 2012 by Tech Librarian, Tracy Mehlin

In July 2012 the Institute of Museum and Library Services awarded a Museums for America grant to UW Botanic Gardens to integrate an all-inclusive database, using Geographic Information Systems (GIS) technology. The multi-part project will ultimately allow for one point of access to herbarium, horticultural and curitorial records linked to an Arc-GIS generated map, searchable from any web-connected devise. The database will be used to advance environmental research, improve Arboretum management and expand interpretation of the woody plant collections.

The first major task starting as soon as survey equipment arrives will be to measure and verify the geospatial coordinates of the physical monuments of the historic grid system used in the Washington Park Arboretum. These coordinates will be used to create a map that supports the geo-referenced database.
