Whether you are interested in what grows in the woods nearby, which plants are not native, how to identify a plant by its winter twigs, where to glimpse roadside displays, when to photograph the wildflowers, where to hike to stunning vistas, or learning more about our rare plants, numerous resources are ready to get you started.

A solid beginning is to understand Washington’s natural history and how volcanic and glacial geology has made our soils, climates, and ecological niches. Or you could take first steps on the life long journey of identifying native plants . A 10x magnification hand lens makes it even more fun! Start with the most common 20, expand to 50 …and so on. The lily family has easy to recognize beauties. Grasses and sedges might take a dissecting microscope and bushels of patience. Labeled native plants in public gardens make first attempts at identification less intimidating. Need tips on venturing out and enjoying native plants in the wild ? Whatever level of activity you choose to learn more about Washington’s native flora, let the fun begin now!

Identifying Native Plants - Useful Field Guides

Botanist’s primarily use the Flora of the Pacific Northwest by Hitchcock and Cronquist to differentiate plants first by FAMILY then down to subspecies. Pojar’s and Parish’s field guides are handy for ID, ecology, and ethnobotany information. As a rule, line drawings of features are more descriptive than a photo. The other texts listed here vary in format (drawings or photos) and focus (region, site, or habitat). If a book is out of print, the Botanical Resources - Elisabeth C. Miller Library at the UW’s Center for Urban Horticulture or 206-543-0415 may have a copy.  Other libraries throughout the state may also be checked.

Enjoying Native Plants in the Wild – How, When, Where

To practice your new identification skills, now it’s time to explore local parks and plan trips to catch the seasonal native flora highlights around the state. As visitors to the native plant’s home, please follow the “Leave No Trace” backcountry ethic and abide by the universally accepted policy of not removing wild plants or any parts without permission. You might want information about backcountry hiking and where to obtain permits and maps. Links to outdoor organizations, state parks, natural preserves, national forests and parks, and wildlife refuges will expand your possibilities. Maybe you need to know were accessible ( ADA) sites are located. Many native plants are endangered, threatened or sensitive primarily due to habitat loss and invasive plants. Knowing which plants are at risk and those that damage ecosystems is another exciting aspect of appreciating our native flora. Please help our native flora remain strong and wild.

  1. Take self-guided tours of Seattle parks and environs: www.cityofseattle.net/parks.

  2. Download WNPS plant lists by Washington counties for more than 300 favorite sites compiled by WNPS members over the years - then happy hunting!
  3. Join WNPS for guided monthly field trips (varies by chapter).
  4. Read Leave No Trace – Minimum Impact Outdoor Recreation by Will Harmon, a Falcon Guide, Helena, MT., 1977. The Mountaineers posts this crucial information on its web site as well.
  5. See The Mountaineers website for wilderness hiking ethics, essentials, safety and first aid, climbing skills, and class information plus links to forests, parks, and permit needs. The Mountaineers hiking guidebooks, available through many book retailers, are packed with directions, descriptions, difficulty levels, seasonal access, cautions and more. Checking weather, avalanche, flood, and road/bridge conditions before each outing will help you have a safer, more enjoyable trip.
  6. Obtain maps from Metskers Maps in Seattle, from R.E.I. stores, The Mountaineers, and U.S. Forest Service.
  7. Enjoy Washington’s 120 state parks, some with ADA access.
  8. Hike in Washington’s unique, rare and/or scenic ecosystems as designated by the Botanical Resources - Washington Native Plant Society. There are currently 49 Natural Area Preserves protecting the finest remaining examples of bald, bogs, canyons, prairies, etc. The 28 Natural Resources Conservation Areas save at risk or scenic ecosystems for the future.
  9. Learn about the U.S. Forest Service Region 6 covering Washington and Oregon. Visit the six Washington national forests and three special areas – Alpine Lakes Wilderness, the Columbia Gorge National Scenic Area, and Mt. St. Helens National Volcanic Monument.
  10. Drive to roadside vistas to appreciate the plants and habitats of ten areas in the Columbia Basin. Order “Watchable Wildflowers” and “Watchable Wildlife” guides from the Bureau of Land Management (Dept. of the Interior). The large map is $2.00 plus $1.00 for mailing tube. The wildflower brochure costs $4.00 payable by check or credit card either by mail or phone (no on-line ordering). Brochures for the 10 areas are also available individually.
  11. Explore Washington’s three spectacular national parks: Mt. Rainier, North Cascades, and Olympic. The National Park Service also manages Recreation Areas (2), Historical Parks (3), Historic Sites (2), and Historical Trail (1) in our state. Of particular native flora interest is Ebey’s Historic Reserve on Whidbey Island. See the U.S. Dept. of Interior website .
  12. Combine wildlife and flora viewing on Washington’s eleven National Wildlife Refuges. A variety of recreational and educational opportunities await visitors. Access may be restricted to a limited acreage or be seasonally sensitive. Learn more at the U.S. Fish & Wildlife Service website.

Accessible (ADA) Recreation

Are you unable to walk very far, let alone up an arduous path? Do you rely on wheels (wheelchairs, baby carriages….not skateboards and mountain bikes) to get you out into nature? Since 1993, many of Washington’s 120 state parks have created outdoor recreation opportunities for people with access limitations.

Rare Plants & Species at Risk

Botanical Resources - Washington Native Plant SocietyEach state maintains site-specific data on their rare, endangered, threatened, and sensitive plants. One Washington native is the world’s only known example of that species. Habitat loss and invasive plants are the top two reasons a plant may disappear or decline to a threatened status. Poaching, pollution, pesticides, and pollinator disruptions may degrade habitat as well. The updated version of the 9/97 Endangered, Threatened & Sensitive Vascular Plants ofWashington is available only on-line through NHP’s website. Please see NHP for program details, rare plant regulations, and listed plants by risk category and county.

The Rare Plant Care and Conservation Program at the University of Washington’s Center for Urban Horticulture helps NHP monitor and protect the state plants at risk. Volunteers are trained every spring to expand this effort. For more information on Rare Care, see:
Reichard, Sarah H. et al, Editors. Conservation of Washington’s Rare Plants and Ecosystems. Proceedings from a conference of the Rare Plant Care & Conservation Program, University of Washington, April 17-18, 2000. Pub. Washington Native Plant Society, 2000.

Noxious & Invasive Non-Native Plants

“Introduced, alien, exotic, weedy or even noxious and invasive” are terms given to the wilderness and garden thugs that hog sunlight and water, out-compete for space and nutrients, and even prevent growth and reseeding of native plants through toxic emissions. Most invasive plants are escapees from horticultural imports that were intended for home gardens.

The Washington State Noxious Weed Control Board and county weed boards maintain lists of foreign plants that must be removed or are encouraged to be controlled. English ivy, knotweeds, Scot’s broom, and tansy ragwort are extensive problems west of the Cascades. Knapweeds, leafy spurge, thistles and many others degrade eastern portions of the state. Loosestrife, milfoil, and parrotfeather clog waterways. Spartina and reed canary grass alter shoreline ecosystems. It is the property owner’s responsibility to control listed noxious weeds on his land. That means homeowners and every private or public entity.

What to do? Weed relentlessly and mulch. Don’t plant the listed thugs. Join Ivy O.U.T. and help King County urban parks be free of the invasive weeds. Volunteer to pull weeds in your city, county and state parks. Together we can make a positive difference...one weed at a time year after year.

Washington State Noxious Weed Board includes weed lists, laws, county weed boards and districts, educational resources, and links.

Washington Native Plant Society. Tackling invasive weeds is one of three top priorities for the next five years at WNPS.
