ENVIRONMENTAL HORTICULTURE There is nothing more lovely than wildflowers in your garden. As lovely as they are, wildflowers may also cause harm to natural areas. Because the flowers can naturalize, it is assumed that they are native. However, sometimes they are non-native and invasive. Invasive plants compete with native plants for water, nutrients, space and light. They may also eliminate important habitat and food sources for native animals. Some wildflowers are also listed as noxious weeds which Washington State law (17.10 RCW) defines as “any plant which, when established, is highly destructive, competitive, or difficult to control by cultural or chemical practices.” In a research study done in 2001, the content of nineteen different wildlfower seed mixes were tested to determine if they contained invasive species or noxious weeds. A variety of mixes were selected including butterfly, songbird, drought tolerant and partial shade mixes. Several of the mixes originated in the Pacific Northwest. Six of them did not list their contents. The seeds from all 19 mixes were grown in a controlled greenhouse environment and the flowers identified as they emerged. From the wildflower mixes that were tested, eighty-four species were identifed. Nineteen of these are listed as invasive and four are listed as noxious somewhere in North America (see table on page 5). All 1 9 mixes contained at least one invasive plant and eight mixes contained noxious weeds. Yellow toadflax ( Linaria vulgaris ) is a Class C noxious weed in Washington State. King County considers it a priority weed for which control is mandatory. This invader was found in four locally produced mixes, of which only one listed it on their label. Bachelor’s button ( Centaurea cyanus) was the most frequently observed wildflower, showing up in 15 of the 19 mixes. Although it is not listed as a noxious weed, the Washington State Noxious Weed Control Board lists bachelor’s button on their Education List. This plant is known to invade native grasslands and prairies. So can you have a garden of wildflowers? Although there may be mixes available that do not contain invasive plants, it may be better to avoid wildflower mixes altogether. Only four of the mixes in the study listed all of the seeds they contained, (continued on page 5) for URBAN HORTICULTURE CENTER FOR URBAN HORTICULTURE SPRING 2002 Bring the family to Woodland Park Zoo on Saturday June 1 where the Rare Plant Care and Conservation Program at CUH will host a celebration of Washington’s native wildflowers.

Know Your Compost Ever since WSU detected the herbicide clopyralid in local compost, organic industry folks and the gardening public have been uncertain regarding the implications for organic practices in western Washington. Clopyralid is the active ingredient in herbicides used on golf courses, lawns, pastures, and crops such as sugar beets, corn and mint. Sold under trade names such as Confront, Millennium, and Grazon, it is thought to be relatively safe for humans and other mammals. The herbicide is particularly effective because only one or two applications are required per year. Unfortunately, this means that the compound degrades more slowly than other herbicides during composting. Contaminated compost can be traced to grass clippings, straw and hay from sites that used the herbicide to control weeds. Plants that are most easily damaged by clopyralid are among the most commonly grown garden plants. They include potatoes, tomatoes, peppers, peas, beans and sunflowers, among others. Susceptible plants may exhibit symptoms of toxicity at less than ten parts per billion. Symptoms include stunted leaves, curled tips and reduced bud and fruit production. Although Western Washington composters have fared better than their Eastern Washington counterparts, the potential for clopyralid contamination is still of concern. This is particularly true for manure where the source of hay and straw is difficult to trace. David McDonald of Seattle Public Utilities suggests that people using compost or manure in their gardens this year ensure that the producer has tested the batch they receive. Cedar Grove has done just that ever since the contamination became an issue. Any Cedar Grove product that is certified as clopyralid-free has been shown in bioassays to contain undetectable levels of the herbicide. So until there are more consistent rules governing this herbicide, know your compost! For updated info on clopyralid, visit the WSU website: http:llcss. wsu. edul compost! compost.htm 3 Bees are Abuzz at the Arboretum Signature Bed The Puget Sound Beekeepers Association (PSBA), together with the Washington Park Arboretum, is presenting the signature bed for this year entitled “Urban Bee Garden: Pollen and Nectar Sources for the Honeybee.” Designed by Jennifer Cochrane, the bed has a whimsical appeal with its topiary five- foot bear and four flying honeybees. Nectar and pollen-producing plants in the bed include raspberries, lavender, red flowering currant, crabapple, fuchsia and bee balm. They start blooming in March and will give people a chance to view pollinator-friendly plants that grow well in the Northwest. A plant list is available at the Graham Visitors Center along with a display of bee hives used around the world. PSBA has provided the Arboretum with honeybee apiaries for over 30 years. The hives are visited weekly from April 1 5 to November 1 3 by members who collect the honey and sell it at the Arboretum Gift Shop. The apiaries serve to pollinate the extensive plant collections at the Arboretum. PSBA members hope that the “Urban Bee Garden” will teach people the difference between honeybees and their more aggressive and carnivorous cousins, the yellowjackets. Visit the PSBA website at http://www.pugetsoundbees.org for more information on beekeeping in the Puget Sound area. CENTER FOR URBAN HORTICULTURE SPRING 2002 News from CUH Gardeners Ask the Darndest Things! As days lengthen and the soil warms up, the reference desk at the Miller Library heats up, too, with a wide variety of questions from gardeners intent on spring planting and garden chores. The library reopened in December in Isaacson Hall. Please stop in to use our reference collection, computerized resources, or to borrow books from the lending collections. Here is a sampling of recent questions answered by our Plant Answer Line: QUESTION: Since last summer I have had lots of (fruit) flies in my vermi-composting bin in the basement. Short of washing all the worms and starting over, how can I get rid of them? 4 Plant Answer Line The Plant Answer Line is open from 9 a.m. until 5 p.m. Monday through Friday. Call UW PLANT, 206-897-5268, or e-mail your question to: hortlib@u.washington.edu ANSWER: Worm Digest, Sept. 2001, p. 19 suggests freezing or microwaving fruit and vegetable skins prior to putting them in the worm bin, thus killing any eggs or larvae that may be present. The book Worms Eat My Garbage by M. Appelhof, 1982, p. 63-65 also advises cooking garbage before it is placed in the compost unit. In addition, it recommends traps, which will attract large numbers of fruit flies. Or, if you get desperate, suck them up with a vacuum cleaner! QUESTION: I planted Sarcoccoca confusa in a shady area three years ago and it is not doing well — slow-growing and leggy. It gets plenty of water all year; the soil drains well but does not dry out too much. What can I do to make it bush out and grow better? ANSWER: According to the Hillier Guide to Trees and Shrubs (1995 edition, p. 566), S. confusa does well in alkaline soils that are somewhat dry during the summer. It might be a good idea to test the soil pH and withhold summer water. QUESTION: I would like a good reference book that will give me information on choosing a tree for my lousy, structureless, construction-backfilled clay soil or information on how to create a really good hole (if possible) that will support a tree. ANSWER: There is surprisingly little information about this common urban soil problem! Many resources merely advise about how to avoid the situation in the first place. However, a chapter in Growing Greener Cities ; A Tree-Planting Handbook, by Global ReLeaf (1992) describes, as a last resort, how to construct in-earth containers for growing trees in difficult sites. QUESTION: Can you recommend a comprehensive (and picture-laden), quality plant encyclopedia on CD-ROM? I will be moving frequently while studying in the UK and want to limit the number of books I carry with me. ANSWER: The Library’s favorite CD-ROMs for photos are: • Heronswood Nursery — 800 Favorites, contact Heronswood Nursery, www.heronswood.com • Pacific Northwest Trees, www.pnwisa.org • Armitage’s and Dirr’s compilations, www.plantsamerica. com.

CUH & CFR Faculty 2001 Research List on Web The list of CUH and College of Forest Resources faculty publications for 2001 features two edited books and 51 articles, chapters and reports. It is now available for viewing at the Forest Resources Library home page at http://www.lib.washington.edu/Forest/. Sustainable Community Landscapes Hardworking students under the guidance of Dr. Linda Chalker-Scott restored two urban sites and worked on a total of seven landscape restoration projects this past fall. Neglected areas at NOVA High School and a property near Matthews Beach termed “the triangle” by local residents were attacked with gusto. The students drew up the restoration plans, cleared the site, installed native trees, shrubs and grasses and trained local community members in maintaining the sites. At the Matthews Beach property, the group’s effort resulted in increased plant diversity to provide a more functional wetland. For a description and photos of these projects, see http:// www. cfr. Washington, edu/research. mulch/. 5 Continued from page 1 Therefore, it is probably safest to plant individual species of flowers that you enjoy. There are many alternative flowers that have similar characteristics as the invaders, but do not reseed as profusely.

NAME ADDRESS CITY STATE ZIP DAY PHONE EVENING PHONE FAX EMAIL CENTER /orURBAN HORTICULTURE REGISTRATION FORM University ofWashington Center for Urban Horticulture director’s notes “UW Horticulture Center is Reborn, Finally" was the headline of the February 1 editorial in the Seattle Times. The State Legislature and the University will provide $5.4 million to accomplish this, no small task in an economically depressed time. The above sketch by the Miller/Hull Partnership captures a dream for the new Merrill Hall. How the building unfolds over the next several months will result from considerable hard work by the design team and Center supporters.
