CULTURE RESENTS Spring 1995/Center for Urban Horticulture/Washington Park Arboretum/College of Forest Resources/University of Washington/Vol. 12, No. 2 HIGHLIGHTS THIS SPRING: Herbal Expressions Symposium Specialty Pruning Courses Plant Identification Courses New Zealand Tour Information CENTER NEWS From Director Clement Hamilton Sarah found that invasive woody plants tend to show one or more of these following characteristics: quick vegetative spreading, a short juvenile period, and the seeds requiring no pretreatment for germination. To read more, visit the thesis-and-dissertation shelf in the Miller Horticultural Library, where you can see what Sarah and all our other students have accomplished at CUH. YOU AND THE CENTER CUH PARKING CHANGES CUH is very pleased to announce that, effective March 1 , PARKING FEES WILL NO LONGER BE COLLECTED on entry to lot E-16 (the CUH parking lot)! No longer will you need a pocket full of quarters to visit the library, attend a lec- ture, or get a plant identified at the Washington Garden Clinic, lost horticultural and continuing and public education pro- rams will now enjoy free parking! This change is the latest step in our continuing effort to pro- vide easier access for our family of horticultural groups who utilize the Center, and at the same time lessen the cars parking on the neighboring streets. We hope you appreciate this change, including the lack of “change” now needed to visit us! URBAN INVADERS? The end of this past fall quarter saw the completion of one of the most interesting pieces of research ever conducted at the Center. Graduate student Sarah Reichard, advised by Profes- sor Hamilton, received the third Ph.D. degree in the Center’s history for studying the properties of woody plants that “es- cape” urban landscapes and invade natural environments. Many such invaders, such as English ivy locally and kudzu in the southeast, wreak untold havoc on native plants. Because about 80% of woody invaders were originally intro- duced as landscape plants, we bear special responsibility for seeing that new plant introductions do not become the next Scotch broom. Dr. Reichard compared invasive versus non- invasive woody plants and then devised a model to predict invasiveness of new plants. Her model will be useful to fed- (eral and state agencies that seek to protect native flora and tauna, as well as to horticulturists and landscapers who care about natural habitats. Perhaps you were relieved not to have received that annual phon-a-thon call soliciting donations for the Center’s pro- grams. However, the need for public support remains just as strong, and individual gifts to the Center remain critical to our thriving, especially in these days of ever-decreasing state bud- gets. We are thrilled to accept contributions of any size. We work with the University’s Development Office to tailor gifts to the needs and desires of the donors. Major giving opportu- nities on the horizon relate to the development of additional gardens on our Union Bay grounds around CUH. All our pro- grams- the Miller Library, the Ecological Research Natural Area, the Hyde Hortorium, and the Continuing & Public Edu- cation Program- benefit from your support. If you are interested in making a gift to the Center, please tele- phone Clement Hamilton or Barbara O’Neill at CUH at (206) 543-8616. LIBRARY NEWS The library celebrates its 10th anniversary in 1995. Since opening, we have doubled our space, collections, and services. Thanks to our generous donors and hard-working volunteers who have helped us grow. Several special events commemo- rating the anniversary will be announced soon. A generous grant from the Northwest Horticultural Society will again make Monday evening hours and other services possible throughout 1995. We’d also like to extend special thanks to the NHS individuals who made a year-end contribu- tion to the library’s book fund, and especially to Sylvia Duryee for her very generous support. Thanks also to Mary Rupp for donating an extensive collection of fine volumes, in- cluding a 1757 copy of John Hill’s Eden.
