WINTER 1 993/Center for Urban Horticulture/College of Forest Resources/Washington Park Arboretum/Vol. 10, No. 1 . V I CENTER NEWS WINTER TIME Winter is the time for planning, browsing through all those seed catalogs, and mak- ing plans for spring. It's the time for taking part in all those classes and special lec- tures on dark, cool days. So, along with our own CUH events, don't forget the 1993 Northwest Flower and Garden Show-five days of seminars, demonstra- tions, exhibits, and garden viewing on February 1 1 -1 5. The winter palette is full. I/Vhy not succumb to a little overindul- gence? ; ~ NEW DIRECTOR ANNOUNCED Clement Hamilton, associate professor of horticultural taxonomy, has been named Director of the Center for Urban Horti- culture. Dr. Hamilton joined the Center faculty in 1 985. He is responsible for the development of the Otis Douglas Hyde Hortorium, several new academic courses involving the selection and use of plant materials, and research on plants in winter-rain regions around the world. He has been Acting Director since Janu- ary. FORMER DIRECTOR RETURNS Dr. H. B. Tukey, Jr., founding director of CUH returned early this fall to his faculty position after a sabbatical during which he lectured at many universities, gar- dens, and horticultural meetings around the world. He was also recently ap- pointed a vice president 6f the Royal Horticultural Society in London, En- gland.

COMPOST DEMONSTRATION PLANNED The City of Seattle Solid Waste Utility has awarded a grant of $31 ,000 to Drs. Wott and Ewing for the construction of a "Pub- lic Demonstration Plot Regarding the Use of Seattle Solid Waste Compost". Graduate assistant Stephanie Allen will be evaluating the growth of plants in several mixtures, including Cedar Grove compost. The trial beds are being con- structed just south of Merrill Hall atCUH, with planting expected in spring. Special signage and brochures will be produced and the public is invited to stop by and view the demonstration area. The resi- dents of Seattle have always been leaders in recycling; now we need to discover how to best use these compost products.
