CUH Update – SPRING 2012

May 25th, 2012 by Soest Gardener, Riz Reyes

Finding the time to do a regular update has been a challenge as this
time of year demands so much of our time as the gardens take on a life
of their own! With only two gardeners (one half-time and one 3/4 time)
overseeing the grounds, we must scramble to get on top of things and
sometimes it doesn’t always happen.
The gardens, somehow, find a way to look fabulous and put on a show like no other.

MvVay Courtyard revovation:
We have just completed the first phase of a redesign and renovation of
the McVay Courtyard here at the Center of Urban Horticulture. In the
next couple of months, we will slowly transition into a new look thanks
to UW Professor in Landscape Architecture, Ian Robertson. His aim is to
integrate more architectural plants and add much needed color and
vibrancy to the space.

CUH McVay Renovation
In this brand new makeover of this bed, we’ve relocated the existing
ferns to make room for striking Manzanitas
(Arctostaphylos cvs.), azaleas, and an assortment
of various bulbs including Nerine, Amaryllis, and Lilies.

Seattle Garden Club’s Scented Garden:
After 5 years since its installation, the Fragrance Garden is another
one that has has taken on a life of its own as the beds are just about
full and plants have really had a chance to get established.

Now it’s just a matter of editing and ensuring that there’s color (and fragrance, of course) all throughout the year.

Visitors might be wondering what’s happening up front; it’s getting kind of weedy and the horsetails are back in full force. It’s just one of the challenges we have in maintaining the grounds with just 2 part time gardeners, but we’ve been recruiting volunteers and partnering with the Hardy Plant Society of Washington
who have something spectacular in store as they are gathering troops to take on this challenge and transform this site into a most spectacular perennial border! There’s so much to do and they could really use a few hands during their work parties. If you’re interested in volunteering and being a part of what’s expected to be a traffic-stopper, check out the link to their site.

It’s time to assemble our seasonal containers; both indoors and out! We’ve been trying to keep our small foyer in the Douglas Conservatory actually look like a conservatory with random tropical plants we’ve nursed back to health and put on display here. These have also been the source of plant material for ESRM 411 (Plant Propagation).

Untitled
The cutting lab is always a fun activity and I had an opportunity to help out this quarter! They take a wide assortment of cuttings utilizing various techniques and treatments. If they are successful, they’re able to take their new starts home and just marvel at the fact that they started a new plant from just a single section of stem and brought it back to life!

In Remembrance..<br />


So it’s been about 5 years since I started working in the Soest
Perennial Display Garden and in that time, I’ve had the pleasure of
meeting and interacting with the Soest family. This February, we were
saddened by the passing of Orin Soest. Alongside his wife, Ally, it was
always a treat to see them visit and walk them through the splendid
garden that bears their name. Even in his fragile state just a few years
ago, Orin still insisted on seeing the beds and always marvelled at
just how much it has grown and evolved.
 

I’ll always admire him as a kind and generous man who wasn’t afraid
to smell the flowers. In fact, one of this favorites was a highly
scented English Rose called ‘Gertrude Jekyll’, which should be in bloom
in a few weeks in June and into July. Please come by CUH and the Soest
Garden and help me remember Orin by sampling the scent of this
exceptional rose and admiring a garden that will continue to live on in
his honor. His presence, both in and out of the garden setting, will
truly be missed.

Service Learning at the ARB

May 17th, 2012 by Arboretum Education Supervisor, Patrick Mulligan

Posted on behalf of Alyce Flanagan, UW student intern

our first planting


This spring one of my classes gave me the option of doing a service-learning project instead of writing a research paper. I jumped at the opportunity to gain some sort of real world experience instead of sitting in the library.  I ended up volunteering in the vegetable garden at the UWBG Arboretum, and it has been an enjoyable experience.  It is great to have an excuse to spend a few hours outside, get dirt on my hands and learn about growing food.  The class that my arboretum service learning is connected to is Global Food Policy.  Modern cultures have become extremely disconnected from our sources of food.  Technology allows for the mass production of cheap food, and working in a garden has given me perspective on how what it takes to grow vegetables.

Food is a vital resource that is frequently taken for granted.  Growing and gathering food is something that was an integral part of our ancestors’ lifestyles.  In recent years, we have grown away from this routine.  Food is bought from the grocery store, and we have only a vague idea of where it was before that. My Global Food Policy class looked at where food was before it got to the store.  Our severe disconnection from the production of the food we eat is unfortunate, but it is a system that we are totally reliant on. Learning about food; where is comes from and how its grown, is the first step to not taking food and this its large scale production for granted.

Food sovereignty is an issue that relates to peoples right to decide what food they eat, where it comes from, and how it is produced.  In America, most people would say that they have the right to choose their food, but in reality, much of our food is under the control of a few big agricultural businesses.  Growing at least some of our own food is an important step towards food sovereignty.

future pickles

The vegetable garden at the UWBG Arboretum is intended to teach children about the process of growing food, and hopefully inspire in them an interest in growing their own food. Volunteering at the Arb has done just that for me.  Watching plants grow over the course of a few months is somehow exciting and motivational.  Hopefully sometime in the next few years I will be able to start a garden and become at least a little less reliant on the mysterious system that produces food that feeds the world.

I am looking forward to visiting during the summer and seeing how the garden has changed.

Did you know that the Washington Park Arboretum often serves as a research site for researchers at the School of Environmental and Forest Sciences? Recently, researchers at UW have been using the Arboretum to study LiDAR and its applications. LiDAR (Light Detection and Ranging) is a method of airborne laser scanning that can be used as a tool to inventory and manage forests. Below are some of the research papers discussing their findings.

Cash donation helps vandalized garden recover

May 10th, 2012 by Tech Librarian, Tracy Mehlin

In early May UWBG suffered a sever vandalism attack of  in the Gateway to Chile garden. This follows similar vandalism last May in the same location and in some cases, the same plants.  KOMO news covered the story with an interview with the Manager of Horticulture, David Zuckerman:

 

Yesterday Director Sarah Reichard received a call from a private banker representing an anonymous donor and by late yesterday UWBG had a check to cover the estimated costs to replace plants and repair the damages – $43,000!

Director Reichard reassured staff in an email announcing the donation that the investigation continues:

“This does not mean we will not continue to assist the police to track down the guilty parties but I hope you feel – as I do – that your faith in human nature at least a little bit restored.”

Seattle Parks and Recreation, the Arboretum Foundation, and the UW Botanic Gardens ask anyone with information about the crime to contact the Seattle Police Department’s East Burglary Unit at 206-684-4300

Donations can be made through the University of Washington Foundation.

May 2012 Plant Profile: Geum ‘Totally Tangerine’

May 4th, 2012 by Soest Gardener, Riz Reyes

One of the best performing new plants the past two gardening seasons has been this incredibly vigorous Geum. A genus not often used here in gardens (I don’t have any idea why), this selection was given to us by Skagit Gardens who asks us to evaluate its performance. So far, it’s been so dependable, relatively low maintenance (just need to shear back after the first main flush to allow it to continue blooming through the summer. What’s remarkable about this plant is it remains somewhat evergreen and flower buds appear as early as March, ramps up in April and is in full spectacular bloom in May and into June and sporadic flushes throughout the summer. It looks smashing right now paired up with Euphorbia ‘Fireglow’ in Bed 8 of the Soest Garden.

Common Name: Avens
Location: Soest Garden – Bed 8
Origin: Garden Origin
Height and spread:
2.5ft high x 2 ft. wide
Bloom Time: Early Spring
Growing Conditions: Full Sun/ moderately moist soil.

Register Now for Arboretum Summer Camps

April 29th, 2012 by Community Programs Assistant, Sarah Heller

During the Seattle Public Schools’ Spring Break week, the Washington Park Arboretum hosted a spring-themed camp program for ten students in 1st-5th grade. Scroll through these photos and captions to see how much fun we had and how much fun YOU could have at our Summer Camps this summer!

On the first day of camp the students came up with our team name – The Buzzing Bees. We did lots of bzzzzzing during the week and there was a bee-themed mural made to honor our team name.

A pair of campers play Meet-A-Tree. The blindfolded child is getting to know his tree with all of his senses – here he is licking the tree (DON’T TRY THIS AT HOME:)! His partner is waiting until he feels like he knows his tree well enough to find it later. She will walk him (blindfolded) back to the starting spot, making sure to take a new path. There she will take off his blindfold and he will have to find his tree!

One day we made an edible salad from native plants. The campers all proclaimed that they do not like salad so we came up with two new names – Wild Greens and Garden Yum! The concoction consisted of wood sorrel, big-leaf maple flower buds, salmon berry flowers, red huckleberry flowers, and dandilion flowers and leaves. We also made teas during the week from stinging nettle, the western hemlock tree and western red cedar.

 

 

On Monday we worked as a team to do the Bird-Themed Scavenger Hunt, which took us through the wetland area in search of birds with informational tags on them. We sucessfully found all the birds and cracked the code! At the tip of foster island we took a break in the sun to make daisy chains, explore the water’s edge and do a WAM (Water Appreciation Moment – someone says something they are thankful for and we all take a big sip of water).

We also made some time to let free giggles and energy while playing tail tag! Everyone has a tail and the objective is to steal as many tails as you can without having your own tail stolen.

Wednesday was our water day – we visited the two woodland ponds to see what’s in them. We brought along some tools: small and large dipping nets, white-bottomed trays, pipettes, and field guides. It’s still early spring, but we did find a variety of egg sacs, an aquatic earthworm, a snail shell, mosquito larve and a water strider.

It’s the time of year to plant and prep gardens for a full season of growing food. We grow vegetables in garden beds behind our greenhouse to use during summer camp. Spring break campers helped us out by weeding the beds and planting kale and lettuce starts. They also painted a pot and planted seeds in it to take home, and made mosaic garden tiles to either put in our garden or take home.
