Explorers & Botanists
Native plants have been systematically collected and documented for science since the beginning of the 17th century. Glimpse into this history and you will find the people and places associated with the plants and the wildlife in your Heritage Garden. Include in your Heritage Garden plants whose names honor these explorers, botanists, and in one case, the name of a ship that brought them here.
In 1792, Captain Gray sailed the Columbia Rediviva into the river that he named after his ship. The river, its basin, and numerous flora now bear the name Columbia. Look for plants with names including Columbia, Columbian, columbianum, columbiana.

Lewis & Clark
Between 1803 and 1806, the Corps of Discovery took Meriwether Lewis and William Clark along the Snake and Columbia Rivers where numerous plant species were discovered for western science. Many observations were made throughout their trek and indigenous territories and uses for various plants and animals were extensively described.
Include in your Heritage Garden species noted in Meriwether Lewis' journals or that were collected on the expedition. Look for plants with names including Lewis, Clark, Lewisia, Clarkia and lewisii.
“When I consider the melancholy fate of so many of botany's votaries, I am tempted to ask whether men are in their right mind who so desperately risk life and everything else through the love of 'collecting' plants.”
- Carolus Linnaeus, "Glory of the Scientist," 1737
David Douglas (1798 - 1834)
The most famous botanical explorer of our area, hundreds of plants are named after David Douglas, a Scottish botanist. He began collecting along the Columbia River in 1825. Look for plants with names including Douglas, douglasii.
A Journal kept by David Douglas during his travels in North America, 1823-1827, together with a particular description of thirty-three species of American oaks and eighteen species of Pinus, By: Douglas, David, 1799-1834. Published: (1959)
David Douglas, a Naturalist at Work: An Illustrated Exploration Across Two Centuries in the Pacific Northwest, a book by Jack Nisbet, is a colorfully illustrated collection of essays that examines various aspects of Douglas's career, demonstrating the connections between his work in the Pacific Northwest of the 19th century and the place we know today. From the Columbia River's perilous bar to luminous blooms of mountain wildflowers; from ever-changing frontiers of technology to the quiet seasonal rhythms of tribal families gathering roots, these essays collapse time to shed light on people and landscapes.
Finding David Douglas, a documentary film follows the short life of David Douglas as he explored western North America in a time before white settlement altered the landscape. He discovered and introduced more than 200 new species to the gardens and forests of Europe.

Top Self-Taught Botanists
Thomas Jefferson Howell (1842 – 1912)
An American botanist, Howell collected tens of thousands of specimens throughout Oregon and southern Washington. His specimens were sent to the Gray Herbarium, sold to other botanists eventually going to major herbaria in the U.S. and Europe. His publications include: A Catalogue of the Known Plants, (Phænogamia and Pteridophyta) of Oregon, Washington, and Idaho (1887); A Flora of Northwest America containing brief descriptions of all the known indigenous and naturalized plants growing without cultivation north of California, west of Utah, and south of British Columbia (1903).

William Conklin Cusick (1842 - 1922)
An American botanist, Cusick's primary areas of exploration were the Wallowa and Blue Mountains. He sent his collections to Asa Gray to be named. Gray was so impressed with his work that he sent his assistant to visit Cusick to show him how to improve his collecting techniques and record keeping. Charles Vancouver Piper also encouraged Cusick. Together they collected in the Wallowas. Cusick's herbariums went to the University of Oregon and Washington State University. See also William Conklin Cusick Papers. Look for plants with names including Cusick, Cusickiella, cusickii: Such as Dodecatheon pulchellum (Raf.)

Wilhelm Nikolaus Suksdorf (1850 - 1932)
German-American botanist that became one of the leading collectors of the Pacific Northwest. His drawings and specimens eventually led him to work for Dr. Asa Gray at Harvard. "Over that lifetime he pressed, mounted, and identified over 150,000 wildflower specimens. He collected nearly 400 plant specimens that were considered new to science. Seventy were named for him by his colleagues..." Suksdorf died in Bingen, WA. Additional information at Wilhelm Nikolaus Suksdorf Papers; Suksdorf's story in the Washington Native Plant Society blog, Botanical Rambles. Look for plants with names including Suksdorf, suksdorfii: Such as Mimulus suksdorii (Suksdorf's monkeyflower).
German born, Pursh came to North America where he worked for American botanist Benjamin Smith Barton classifying specimens provided by Lewis and Clark. He eventually left Barton and travelled to England, taking specimens from Lewis and Clark with him. In Europe he published Flora Americae Septentrionalis, A Systematic Arrangement and Description of The Plants of North America. There is no known portrait of him. Look for plants with names including Pursh, purshii.
Archibald Menzies (1754 - 1842)

John Scouler (1804 - 1871)
Scottish naturalist, Scouler studied under William Jackson Hooker. Hooker secured for Scouler an appointment on board the Hudson's Bay Company's ship William and Ann on its expedition to the Columbia River. David Douglas accompanied Scouler on this expedition. Together they discovered many new plant species.
Look for plants with names including Scouler, Scouleri, scouleriana, such as Salix scouleriana (Scouler willow).
Asa Gray (1810 - 1888)

Look for plants with names including Gray, Grayia, grayi, such as Grayia spinosa (spiny hopsage).
Scottish botanist and friend of Sir Joseph Dalton Hooker, the genus Lyallii was named after him by Hooker. He accompanied in the survey of the boundary line between British Columbia and the United States possessions, from the Gulf of Georgia to the summit of the Rocky Mountains, bringing home a magnificent herbarium. His work resulted in the first scientific portrayal of various zones of vegetation in British Columbia.
Look for plants with names including Lyall and Lyallii, such as Astragalus lyallii (Lyall's milk-vetch).

Spokane-based teacher and naturalist, Jack Nisbet is the author of several books that explore the human and natural history of the Intermountain West. He honored us by authoring the foreword to our book, Plant Selection Guide, Heritage Gardens of the Columbia River Basin, and has been a guest speaker at our Heritage Garden workshops.
"Knowing about the people who collected, studied, described, named, and cataloged the plants of an area gives us a better understanding of the history of that area, the relationships among scientists and explorers at that time, the progress of science, and the rigors endured in the quest for knowledge and beauty." -Al Schneider
"People who are Plant Explorers are different from those who are plant hunters, in that their goal is discovery more than acquisition. Plant Explorers today are often botanists or botanical photographers and painters, but can be anyone with a real love for nature and plants. If you are a Plant Explorer, or just someone who loves plants, then this site is for you..."
