Oregon Fawn Lily, Erythronium oregonum.


The Fawn lily, Erythronium oregonum, and its many common names.

Erythronium oregonum has many common names- giant white fawn lily, Oregon fawn lily, dog’s tooth violet, trout lily, adder’s tongue, lamb’s tongue. Maybe this is why the Historic Deepwood Estate here in Salem, Oregon- where I live- has chosen the scientific name for their annual spring native plant festival. Not wishing to confuse people with a common name that is not “common” to all, they use the scientific name Erythronium (pronounced, err- ih-throne- ee-um.) Personally I find it much more useful to use the scientific name for the same reason. Never underestimate the creativity of humans to come up with interesting and numerous common names for one plant, and though they are lovely, ultimately they are rather confusing, especially when trying to communicate which plant you mean to someone.

My first fawn lily, Erythronium oregonum.

Erythronium oregonum was one of the first bulbs I planted in my own garden when I moved to Oregon many years ago. It has since seeded itself throughout my front yard, totally ignoring all my efforts to corral this charming spring bloomer into an attractive sweep of creamy yellow. It was one of these flowers that I used for my botanical illustration above, and inspired me to create my Pacific Northwest Native Plant Greeting Card Series.

The fawn lily and early plant explorers.

When I first saw this beautiful fawn lily here in the Willamette Valley I assumed it must have been collected by Lewis and Clark or David Douglas in the early 19th century. This is not the case. The first fawn lily to be described from this part of the world, pink fawn lily, Erythronium revolutum, was collected by Archibald Menzies in 1793 and described by James Edward Smith in 1809. Then in 1806 the fawn lily’s mountain “cousin” the glacier lily, Erythronium grandiflorum, was brought back by Lewis and Clark (Lewis called it a dog’s tooth violet in his journal) and described by Frederick Pursh in his Flora Americae Septentrionalis in 1814. (for more on the collection see my blog  The saga of the Lewis and Clark Plant Collection and the Irish nurseryman Bernard McMahon’s unwitting role in its fate!.) The glacier lily, Erythronium grandiflorum, also has other common names including yellow fawn lily and yellow avalanche lily.

The common fawn lily, Erythronium oregonoum, erroneously mis-identified.

It wasn’t until 1935 that the more common fawn lily, Erythronium oregonum, was finally described by the Oregon botanist, Elmer Applegate. As is often the case with plant exploration and identification, the story is not that straightforward. According to Applegate “for nearly a century this familiar plant has been known erroneously as Erythronium giganteum Lindl. or as Erythronium grandiflorum var. albiflorum.” ( Kalmiopsis Vol. 10 2003. Native Plant Society of Oregon.) So maybe my assumption wasn’t so far off the mark. Is it possible that some of the Erythronium grandiflorum bulbs collected by Douglas (April, 1826 and 1827) may have been Erythronium oregonum after all?

Elmer Applegate and David Douglas.

There is a tenuous link of a different kind between Applegate and Douglas. Applegate’s wife Esther Emily Ogden was a niece of Peter Skene Ogden (the well-known fur trader and chief trader with the Hudson’s Bay Company.) Douglas met Ogden August 30, 1826 at Fort Vancouver, Washington, directly after Douglas’ exciting 12-day descent of the Columbia River from Fort Colville in eastern Washington. During that descent he had a lucky escape when his canoe was wrecked at the Dalles; causing him to loose the insects he had collected in the interior and some seeds, but he managed to save bulbs of the glacier lily, Erythronium grandiflorum, collected in the Fort Colville area. In April the following year, while on his journey overland to Hudson Bay to meet his ship bound for England, he collected more of the glacier lily in the same area and transplanted them in the hope of keeping them growing all the way to England. Maybe it was these particular transplants that were the first fawn lilies that he is credited with introducing into England. Now I wonder if they were all glacier lilies: if some of the Oregon fawn lilies had not been introduced into the mix also?

When I drive by the Deepwood Estate along Mission Road here in Salem and see the expanse of pale yellow that is the fawn lily, it’s hard to imagine that Douglas didn’t see them while traveling though the Willamette Valley. At any rate, it is a wonderful sight to see and, no doubt, it will be enjoyed by the many visitors to the festival next weekend- Friday and Saturday April 5 and 6.

Pacific Northwest native- red flowering currant, Ribes sanguineum- a favorite on both sides of the Atlantic!

Red flowering currant, Ribes sanguineum.

My botanical illustration this week is part of an on-going series I am creating – Pacific Northwest Native Plants. Sadly, the actual shrub from which I sketched this illustration is no longer alive, having succumbed to a bad ice storm several winters ago. I have since planted more red flowering currants, Ribes sanguineum, in my yard but I am glad to have this botanical illustration as a souvenir of that plant. It was a very fine specimen.

A favorite with the humming birds!
This lovely shrub is native to the Willamette Valley, Oregon, where I now live, but it is also fairly common in Ireland – where I come from originally. I remember it as a child growing in the hedge between my garden and my neighbor’s. I didn’t pay much attention to it, as I didn’t like its “perfume”. I have since discovered that humming birds have no such scruples –or a very different sense of smell to humans- because the red flowering currant is a sure favorite with them here every spring.

Thanks to Archibald Menzies and David Douglas.
Thinking of those childhood memories got me wondering about how long the red flowering currant has been in Ireland- a pretty long time as it turns out, thanks to two Scotsmen – Archibald Menzies and David Douglas. Menzies was the first to bring the shrub to the attention of botanists in Britain in the late 1700’s. But it was David Douglas who brought back the viable seeds that became the first red flowering currant shrubs grown on that side of the Atlantic.

In 1825 the London Horticultural Society sent Douglas to the Pacific Northwest; his task was to collect plants that were already known to British botanists but had not been introduced into cultivation. He more than fulfilled this task, not only introducing many already described plants but also “discovering” new ones.

David Douglas – seed collector extraordinaire!
So successful was Douglas in his collecting that he overwhelmed his clients with vast amounts of seed obliging them to redistribute the surplus to other nurseries. According to the Horticultural Society of London the proceeds from selling this shrub alone more than paid for Douglas’ trip to the Pacific Northwest and to this day the red-flowering currant remains one of the most popular flowering shrubs in Britain.

Nurseryman Bernard MacMahon and the Oregon native plant with an Irish connection.

Mahonia aquifolium syn. Berberis aquifolium.

Tall Oregon grape, Mahonia aquifolium- Oregon’s state flower and its Irish name!

I’ve always marveled at how something as fragile as a plant can end up thousands of miles from its original home: collected and pressed into herbarium specimens or more amazingly, kept alive on long transcontinental journeys and treacherous sea voyages.  Somehow they avoid destruction and are finally transplanted into a foreign soil and there, not only survive but thrive.

I must confess I feel a certain affinity with these well-travelled plants. I am also a transplant from a far off land having emigrated to the U.S. from Ireland. However, my journey was pretty uneventful and mundane when compared to the fortunes of these early pioneering plants and their adventurous collectors who often risked everything to bring them back.

As a horticulturist and botanic artist I feel not a small debt to these enduring plants and their collectors. So, when I post my botanical illustrations, instead of writing about their cultivation I prefer to write the human stories behind the plants. The story behind this week’s botanical illustration, tall Oregon grape, Mahonia aquifolium, contains all the elements of a good plant story but it also has another important attraction for me: it connects the place of my birth with my new home in Oregon.

Two scientific names for one plant!

The connection to Ireland lies in the second scientific name for this genus of shrubs. For some reason Oregon grape has two scientific names- Berberis and Mahonia. Generally speaking, botanists use the first name while horticulturists use the second. As a horticulturist I learned to name the genus Mahonia and even though I have been aware of both names for many years it has never bothered me which one was used. Now that I’ve discovered the Irish connection I’m more inclined to favor the latter.

Years ago in Ireland I chose Mahonia aquifolium for my first garden. Back then I didn’t give the plant’s scientific name much thought. It wasn’t until I moved to the Pacific Northwest and discovered Mahonia aquifolium growing in the wild that I began to wonder about its Irish-sounding name.

Irish Nurseryman Bernard MacMahon

That is how I discovered the Irish nurseryman Bernard MacMahon (1775-1816) . Maybe it was because MacMahon had to leave Ireland in a hurry that so little is known about his early life other than he emigrated (probably from Ulster) around 1796. (Some historians suggest that he fled government persecution due to his political leanings towards the United Irishmen.) Fortunately we know a lot more about his life in the U.S.

MacMahon Nursery and Seedhouse.

By the early 1800’s MacMahon had established  a successful nursery and seed business in Philadelphia where many of the up and coming young botanists of the day would gather (including William Darlington and Thomas Nuttall.) However, MacMahon’s main “claim to fame” was his popular gardening book The American Gardener’s Calendar– the first book of its kind to be published in the U.S. It ran to 11 editions and had many admirers, one of whom was President Thomas Jefferson. So impressed was Jefferson with The Calendar that he became a regular correspondent with MacMahon, often trading plants and seeds.

Lewis and Clarke’s Plant and seed collection.

1806, the year The Calendar was published was also the year that Lewis and Clark’s Corps of Discovery returned from the Pacific Northwest. As directed by Jefferson the expedition returned with a trove of plants and seeds collected along the way. Jefferson expected Lewis to publish their description as soon as possible.  Unfortunately, due to his untimely death, publication was delayed. The story of this famous plant and seed collection is an interesting but complicated one with many twists and turns and MacMahon’s, sometimes unwitting, role in its fortunes will be the subject of my next blog. In the meantime, for the purpose of this story, all you need to know is that the collection passed through the grasp of several individuals before finally arriving in the capable hands of MacMahon.

“Classified” seeds!

This was no ordinary collection.  Jefferson passed on the larger portion of the collection’s seed to MacMahon with strict instructions: as federal property he was forbidden to propagate any of the seeds for commercial use and the collection had to be kept secret while its description awaited publication. In spite of these restrictions MacMahon set to propagating and growing the seeds with great diligence and skill and  the plants flourished. He never really benefited from the plants commercially, nor from being able to advertise their existence at his nursery but in the end he was honored posthumously for his efforts. In 1818 Thomas Nuttall named this genus of shrubs for him in his publication The Genera of North American Plants. I suppose one could say the reward for his hard work, loyalty and discretion was immortality in a plant’s name- for which I am very glad – because every time I see this plant I feel the connection between Ireland and Oregon and the distance recedes.
