Gardening with Native Plants.

I love gardening with wild flowers- or native plants as they are more accurately named. Long before I decided to return to college to study horticulture, I was interested in gardening with wild flowers. This has meant that no matter where I live I grow the native species of that area. Since moving to Oregon, nearly 13 years ago, I have happily discovered that many of the native plants from this part of the Pacific Northwest have long been residents of Ireland and the U.K. Thanks to such plant collectors as David Douglas and Archibald Menzies, and a corresponding rainfall, many of the native plants from the Pacific Northwest thrive in the moist, temperate conditions of the British Isles and Ireland.

Native Plant Time!

If you are interested in native plants and live in the Pacific Northwest this is a very exciting and busy time of year. Between April and May there are many local events organized to help you get up close and personal with the native flora. Here in the Willamette Valley of Oregon we have plenty to choose from – wildflower festivals, native plant guided walks and native plant identification classes. If you want to learn more about the native plants in your area- from the showy and colorful to the weird and wonderful- now’s the time. To help you find the right activity here are some links, below, for events in this region but if you search for your own state native plant society or a different native plant organization where you live I’m sure you will find similar information.

Native Plant Appreciation Week.

For me every week of the year (nearly) is native plant appreciation week but spring is one of my favorite times to really admire the beauty and variety of these plants – both in the wild and in my own garden. Many states celebrate Native Plant Appreciation Week (NPAW) around mid-April to early May. Here in the Pacific Northwest the Oregon, Washington and Idaho Native Plant Societies will be celebrating NPAW from April 28- May 4th. Click these links below to find out about the different events they are organizing.

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.

American Sweetgum, Liquidambar styraciflua, and Irish Fall Color?

Sweetgum

© Aislinn Adams 1998

My first American Sweetgum, Liquidambar styraciflua.

The first time I saw an American sweetgum was in the National Botanic Gardens, Glasnevin, Dublin, Ireland. It was autumn and I was a first year horticulture student attending college there. Ireland is not known for its fall color but that sweetgum, growing on a small island in the “pond”, stopped me in my tracks; its glowing orange-red-purple leaves took my breath away. Such a marvelous display would have done New England proud.

I know there’s a whole series of chemical reactions, triggered by temperature and day length, which make leaves turn the colors they do but seeing that sweetgum made me wonder – if Ireland had more N. American native trees like sweetgum would we have better fall color too?

An American native plant.

Sweetgum is native to the eastern U.S.A. but can be found growing in many parts of the country, including on my own street here in Salem, Oregon. It is not popular with many of my neighbors because its shallow roots push up through the concrete pavement causing large cracks. Even though several neighbors have replaced the sweetgums with smaller, more sidewalk-friendly species, there are still enough on the street to give a striking autumnal show- one I look forward to every year.

Ireland can have good Fall color too.

The botanical watercolor illustration above is part of a series I created for Birr Castle Visitor’s Center in Ireland (and part of my botanical watercolor greeting card series.) I worked on these botanical illustrations while staying in Washington D.C. and was happy to use sweetgum plant specimens from my D.C. neighborhood. I have visited Birr Castle demesne many times (I grew up about 20 miles from Birr) but I don’t recall seeing sweetgum growing there. I have no idea how good the Birr sweetgum looks in an Irish Fall but decided to paint it with good fall color anyway as I like to believe that it too can give as good a show as any of the trees here in the U.S.A. After all, the National Botanic Gardens’ sweetgum looked great.

Botanical Illustration and the Joys of Weeding!

Bermuda grass, Cynodon dactylon

Gardening with native plants and the joys of weeding!

I have drawn my fair share of weeds over the past decade for the Washington Post’s “Digging In” gardening column. Some of the weeds I’ve drawn are true to their name without much to recommend them while others can be quite beautiful while still very “weedy”.  I have created botanical illustrations of Bermuda grass (Cynodon dactylon) twice for the “Digging In” gardening column and although I hate to speak ill of any plant, even a weed, I have to admit I’m not a great fan of this grass. It is a real nuisance plant for gardeners across the United States of America, including here in Oregon where I live. Fortunately for me I garden with native plants, mostly in the shade, so I don’t have much trouble with Bermuda grass as it prefers a sunnier spot.

A damned good weeder!

I met a gardener once who was a great native plant enthusiast. I was an intern at Mt Cuba Center in Delaware at the time, very new to the United States and just learning my way. We were both on a native plant trip to the Smokey Mountains. I innocently asked her what she did for a living and, with a twinkle in her eye she quietly replied, “I’m a damned good weeder”. Later I understood what she meant as I learned that she was independently wealthy and not in need of a “living” at all. Gardening with native plants was her passion, her avocation, and as any gardener knows, if you love gardening you do a lot of weeding.

I love weeding.

I like to think of myself as a “damned good weeder” though not independently wealthy. I love weeding. Not the back-breaking Himalayan blackberry pulling variety, though that can have it’s moments, but rather the careful, knowledge-building kind where you learn to distinguish the seedling of a troublesome weed from a welcome native plant. If you garden with native plants you really need to be able to tell the seedlings apart: to separate the team players from the troublemakers so to speak.

Weeding monotonous? Never!

Some people find weeding very boring. I know some weeding can be horribly monotonous, especially the kind where all you do is pull up everything green except your rows of ornamental annuals or showy perennials. This is not the kind of weeding I mean. I’m referring to the kind where you are constantly observing and frequently delighted by some new native seedling found half hidden under the foliage of the mother plant.

I love this kind of weeding also because it allows me the time to enjoy the dank, rotting leaf smell of the soil and the more subtle perfume of less showy native wildflowers, not to mention the “green” scent of lightly crushed leaves, one of my favorite smells.

If you really want to know a plant.

In my last blog I wrote that if you want to remember a plant draw it. Well, if you really want to  know a plant grow it. I have found no better way to get to know the American native plants of my new homeland than by getting down on my knees, up close and personal, weeding.
