Take a Halloween walk in a cemetery

September 29th, 2012 by Tech Librarian, Tracy Mehlin

Ghosts and Goblins in a cemetery for Hallowe’en?

Why not consider lichens as an alternative?  Lichens are friendly and interesting organisms that love to grow on headstones and old trees.  Cemeteries can take on new meaning as a fun place to observe a symbiotic organism made up of a fungus and algae.  You will also learn about common lichens found in an urban environment and take home a user-friendly chart that lists lichens found in your neighborhood.

Always wondered about what lichens are and why they are found on your trees and Rhododendrons?  Lichens are harmless to your plants and add aesthetic value to trees and shrubs.  We can actually use them as indicators of air pollution!  Join Dr. Katherine Glew and the Center for Urban Horticulture on Saturday, October 27 to get a head start on learning lichens from your local cemetery.  You can enjoy Hallowe’en looking for lichens rather that scary witches and pumpkin heads.

Cost: $25; $30 after October 24.

Paths II: The Music of Trees now playing

September 25th, 2012 by Heidi Unruh, UWBG Communications Volunteer

We’ve been closely following the progress of Abby Aresty’s “Music of Trees” project, a sound installation project in the Arbortetum. We’re pleased to report that the installation is up and running. Aresty describes the project as “a series of sound installations that explore the layers and permutations of acoustic space in seven sites throughout Seattle’s Washington Park Arboretum. Each installation creates a sonic dialogue with its acoustic and physical space. The striking forms of the trees and plants, as well as their relationship to the surrounding environments, provide a unique opportunity for the artistic and physical exploration of sound in space.” 

The installation will be running in October on Wednesdays from 3 to 6pm and Saturdays and Sundays from 10:30 am – 1:30 pm throughout October.

The UWBG Kids Digital Photography Contest was a complete success! We had 12 entries, ranging from ages 7 to 16, who submitted some really incredible artwork.

At least one photo of every contestant is displayed at Fuel Coffee on 24th Ave in the Montlake neighborhood.

You can also view all of the photographs on Flickr.

You will note that at both locations we have displayed photographs taken by our Art in the Park Summer Camp kids. Their photos were inspired by their study of Ansel Adams and Andrew Goldsworthy.

September 2012 Plant Profile: Hesperantha (Schizostylis) coccinea

September 5th, 2012 by Soest Gardener, Riz Reyes

This delightful, but seldom grown corm from South Africa is looking the best its ever looked in the Soest Garden here at the Center for Urban Horticulture.  It has been in bloom since early July and there are more buds to come as this particular species is known for its late summer/autumn flowering, which is always quite valuable in the landscape as fall rolls around.

It’s still commonly known as Schizostylis in the trade (Pronounced “Skizo-sty-lis” OR “shizaw-stalis”), but Hesperantha is the correct name. It’s in the Iris family and related to the similar looking Gladiolus, Crocosmia, and Freesia. This particular selection is a lovely one called ‘Torero’, which was developed in Oregon.

 

It prefers moist, but well draining garden soil and full sun. It is absolutely spectacular amongst ornamental grasses and a mature clump can remain in bloom from late summer and sometimes sporadically into the winter depending on how severe our cold weather is here in the Pacific Northwest.

Common Name: Cape Lily, Crimson Flag
Location: Soest Garden Bed 6
Origin: Dwarf selections are of garden origin.
Height and spread: 1.5-2ft. tall and about 3ft. wide on mature clumps.
Bloom Time: Late Summer into Autumn and sometimes into Winter.
