Selected cuttings from the Washington Park Arboretum (November 3 - 16, 2014)

Selected cuttings from the Washington Park Arboretum (November 3 – 16, 2014)

 

1)    Callicarpa bodinieri var. giraldii  ‘Profusion’  (Beautyberry)

  • Native to western China.
  • Ornamental purple berries on display in autumn months.
  • Specimen located north of the Wilcox Bridge by the parking lot.

 

2)    Gaultheria mucronata    ‘Rubra’

  • Native to southern Chile.
  • Formerly known as Pernettya, this particular variety has carmine pink berries.
  • Specimen is located in the Chilean Gateway Garden.

3)   Grevillea victoriae    ‘Marshall Olbricht’

  • Native to Australia. This cultivar is from a seedling, possibly a hybrid, named for the co-founder of Western Hills Nursery in California.
  • Exotic orange flowers persist throughout winter – loved by hummingbirds.
  • Specimen located in the Australian entry garden at Pacific Connections.

4)   Quercus cerris   (Turkey Oak)

  • Native to southern Europe.
  • Notable for hairy caps on the acorns. Trunk can reach six feet in diameter.
  • Specimen located in the Viburnum Collection near Lake Washington Boulevard.

5)   Wollemia nobilis   (Wollemi Pine)

  • Not a pine, but a member of Araucaceae, the family of the Monkey Puzzle Tree.
  • Wollemia was known only from fossil records until it was discovered in Australia’s Wollemi National Park in 1994 by David Noble, hence its name.
  • Our specimen is growing at the bus turnaround on Arboretum Drive.

Arboretum Loop Trail nears construction start

At long last, the Arboretum Loop Trail (ALT) appears to be just a few months away from the start of construction. “Right now, it looks like the tentative start date would be late spring 2015,” said Raymond J. Larson, Curator of Living Collections for the UW Botanic Gardens. “The idea is to start after most of the rain has passed and to do construction over the drier months.’’

Depending on the the bids received, Larson said the project may be done in two phases. The first phase would be from E. Madison Street to the Boyer/Birch parking lot along E. Lake Washington Blvd. (across from the Holly Collection), he said. The second phase, in 2016, would be from the Birch Lot to the Graham Visitors Center. Larson said, however, that it could also happen all at once. “It depends on a variety of factors,” he said, “and the contractor selected.”

But before any work begins, “the first thing we will do in the field is contract out the transplanting of collections,” said David Zuckerman, Horticulture Manager for the UWBG. “This work will begin as early as this fall sometime, even if it’s just root pruning,” he said.

The ALT is expected to have several benefits for the Arboretum.  “First, it will get people into areas of the arboretum that are currently less well known and visited,” Larson said.  Most people don’t make it to the viburnum collection or know where it is, and don’t get through the Flats (where birches, poplars and the creek is) much of the year because the ground is too wet and there are no trails there, Larson said.  “The ALT will also open up a new route through the largely undeveloped southern hillside across from the Japanese Garden and will provide another way to access the Pacific Connections Gardens,” said Larson.  That is an area currently difficult to navigate and where it is easy to get disoriented (especially for new or occasional visitors), Larson said. Access is going to be much better and the park should feel bigger, he said.

The collections themselves will also benefit. “We will have many new planting areas that will be accessible and viewable,” Larson said.  Some of these will anticipate future phases of the Pacific Connections China and Chile ecogeographic gardens.  “Where the trail crosses through these areas we will be planting plants from those areas along the way,” Larson said.  Other areas will see the addition of a diversity of new plantings that strengthen existing collections (viburnums, oaks, rhododendrons, etc.). “There are going to be a lot of new plants going in, and areas with a lot of ivy and invasives will be refreshed,” he said.

All of this adds up to a better visitor experience—finding your way more clearly as you navigate through the gardens. The north end will be enhanced with better sightlines and a clearer, more obvious connection to the Graham Visitors Center, where the trail forms a loop with Arboretum Drive E, Larson said.  It should feel less hidden and more welcoming.  Some existing blind spots will be improved and in general areas should feel refreshed.  “We think this will be a popular walking and bicycling trail, and the loop connection should help people better experience more of the park,” Larson said.

A glimpse into the past – a very low tide on Foster Island

November 4th, 2014 by UWBG Communication Staff

By John Wott, Director Emeritus

For many years both Lake Washington and Union Bay had variable water levels throughout the year.  The Army Corps of Engineers allowed the water of the Lake Washington system to drop several feet in order to have enough capacity for heavy spring rains and snow melt.  This frustrated many dock owners and also led to significant shoreline erosion.  Today they try to maintain a steady level, although it is difficult to predict both rainfall and rate of snow melt.

The photograph taken on September 12, 1958, show an extremely low water level on the north end of Foster Island. Currently the water level is usually near the top of the large stone works.  The gentleman standing there gives a perspective of at least a six foot drop.

Looking west is the University of Washington Stadium, which depicts only the southern section (now demolished and rebuilt in 2012). The campus buildings are quite low and mostly indistinguishable, and the smoke stack from the UW heating plant has been replaced with the newer large one.

November 2014 Plant Profile: Callicarpa dichotoma ‘Early Amethyst’

November 3rd, 2014 by Soest Gardener, Riz Reyes

IMG_7871Beautyberry is starting to put on quite a show and we have a species that isn’t common in Pacific Northwest Gardens. Callicarpa dichotoma is widely known on the East Coast and thrives in their summer heat and humidity. Having had an exceptionally lengthy summer here, our plants of ‘Early Amethyst’ look the best they’ve ever looked in the three years since they were planted out as small 1 gallon pots.

Combined with consistent moisture in full sun, they’re dripping in hot purple pink and look absolutely stunning in the autumn landscape! We hope the foliage has a chance to color up before a hard frost comes. Meanwhile, they are a sight to behold

Family: LAMIACEAE
Genus: Callicarpa
species: dichotoma
Cultivar: ‘Early Amethyst’
Common Name: Beautyberry
Location: CUH Sidewalk Entry
Origin: China, Japan, Korea, Vietnam
Height and Spread: 4′ high x 4-5′ wide
Bloom/Fruit Time: September-frost

What to do with fallen leaves? Arborist Chris Watson considers the options

To rake or not to rake? When asked what homeowners should do with leaves falling from trees growing in city gardens, Chris Watson, the Arborist who cares for the trees at the Washington Park Arboretum definitively stated, “It depends!”

Is the best mulch for a tree its own leaves? Or does that spread disease and pests? Chris explained:

“From a nutrient cycling perspective, ideally the leaves would be left in place where they fall.  Much like a forest, this would reduce the need for additional inputs, such as fertilizer. However, the urban situation is quite different from a forest.  We have introduced plants, soils, pests and diseases, as well as the desire for aesthetically pleasing landscapes.  Leaves blow in the wind and have the potential to clog drains.  Also, the first best management practice for most foliar diseases is to remove all leaves when they fall to reduce inoculum.

“When leaf removal is necessary, I recommend composting leaf material if possible.  The compost can then be used to amend soils around landscape plants.  If leaves are diseased, they should be composted in a way that increases the temperature to sterilize pathogens.  This is difficult to do for the typical homeowner, so it may be best to place leaves in the yard waste bin where they will be processed in a suitable manner.”
