A Glimpse Into the Past

arb 1939 400
The first edition of a new monthly column by John A. Wott, Director Emeritus

Here is an aerial view of the Washington Park Arboretum and the Broadmoor Golf Course in 1939 (In ’39, it was still known as the University of Washington Arboretum). This was just the time when the University and the City had entered into a formal agreement about the establishment of the Arboretum in Washington Park. Note the sparseness of vegetation in the Park and in the Montlake Community. The original set of greenhouses is present. Most of the land on the west side of Arboretum Drive East is vacant. It also shows some of the Victory Gardens and other growing operations for the Park.
Note that there is no SR-520.   (Photo from UWBG Archives)

For the Younger Set: Spring Break Camp at the Arboretum

uwbg educaton-pond dippingCome join us for a week of spring time explorations, investigations and adventures. We will become nature detectives looking for signs of spring. What are the birds telling us? What are the plants doing? Where are the animals hanging out? We will look for clues while playing games, doing spring-themed crafts, reading and telling stories, and adventuring through the Arboretum.

The camp runs April 16-20, 9am-3pm (before and after care available if 6 or more campers sign up). The cost is $225 ($200 for Arboretum Foundation members). More info at 
the UWBG website or give us a call at (206) 221-6427.

Plant profile: Two members of the family Thymelaeaceae

(by Soest Gardener Riz Reyes) I had a hard time deciding on just one plant for the month of March. I was able to narrow it down to two highly notable species. Since they happen to be in the same family, I figured I’d mention the family as an excuse to have two plants this time around.

Daphne & EdgeworthiaOne of these plants, Daphne odora, is familiar to many of us because of its remarkable winter fragrance. The other one is more familiar to collectors and is not as readily available, but just as dramatic and wonderfully scented. That plant is Edgeworthia, the Chinese Paper Bush.

Both are members of a family that’s difficult to define as there aren’t any very obvious diagnostic traits to identify it. In Landscape Plant identification, however, it’s a family known for woody shrubs producing very fragrant winter blossoms. They also have smooth bark and fibers that make them valuable in quality paper making.

Daphne OdoroFirst off, let’s discuss the ever popular Daphne odora. It is, by far, the most intoxicating scent in the winter garden. It has a very heady perfume and some are reminded of Fruit Loops, the children's cereal, when they come close to admire it! The most common selected cultivar of Daphne odora is ‘Aureo-marginata’, implying the variable gold edges on the foliage. This species is evergreen, but ‘Aureo-marginata’ tends to be sprawly and have a poor growth habit. A newer selection called ‘Zuiko Nishiki’ (pictured at right) looks to be a more promising cultivar with a better growth habit. It is more upright and the foliage appears cleaner, more refined, but lacks the gold edge.

Common Name: Winter Daphne
Location: CUH-Fragrance Garden, Miller Library/Merrill Entrance
Origin: China/Garden Origin
Height and spread: 2ft. high and 4ft. wide.
Bloom Time: Winter

edgeworthis chrysanthaEdgeworthia chrysantha has been a much sought after collector’s plant for years, but it’s becoming more readily available. It has a really architectural look to its multi-stemmed habit and light, cinnamon colored stems. It makes a rounded shrub with lush foliage during growing season as it begins to set buds for the following winter’s blooms which are a deep creamy yellow and possess a fabulous scent. They can be finicky to get established. It needs a spot with sun/part shade, and it benefits from a protected location, as it’s not as hardy as the Daphnes of the Pacific Northwest. Rich, well drained soil is a must along with regular irrigation during the summer and fall while buds are setting. Avoid moving it around as mature specimens will sulk if transplanted.

Common Name: Chinese Paper Bush, Yellow Daphne
Location: CUH-Fragrance Garden, Miller Library North beds
Origin: China
Height and spread: 6ft. high and 6-7ft. wide (usually smaller)
Bloom Time: Winter
