Cape Flattery was spectacular and well worth seeing, but the camping options near it leave something to be desired. In particular, Hobuck Beach got crowded sooner than I thought (by Thursday evening; I was expecting it to get bad Friday and as such had planned to leave Friday morning). Worse, it attracts clueless idiots who think it’s a reasonable thing to fire up generators for their RV’s at quarter to five in the morning.

Prompted by that camping experience, I craved balance, so I decided not to go to Lake Ozette on Friday. Instead, I went into the Olympic Mountains and did some dispersed camping on national forest land, because I craved silence and solitude. I figured I could look for high-elevation huckleberries, part of an ongoing search. They’re easy enough to find in the Cascades, but not so easy to find in the Olympics.

And I found them. Not just a few bushes, good for a snack and that’s it (all I’ve found before in the Olympics). They weren’t near where I camped, so on Sunday I packed up and started driving to a spot on the map that looked promising (higher in elevation). The road became impassible before I reached that area, but at the same spot I was compelled to turn around, there they were. I found the silence and solitude, too. It was delightful to fall asleep to the sounds of no other human activity.

Today, for the first time in many years, I made mountain huckleberry jam again.

Tomorrow, I start my new job, which I certainly hope turns out to be a better match than my previous one.

Tall Oregon Grapes (Mahonia aquifolium) are now ripe.

They are edible, but they are also sour, so they tend to be best used as an ingredient for sweetened dishes, rather then eaten as-is. I have however learned that if they are fully ripe (which means not just so dark they are nearly black under their waxy bloom, but actually starting to shrivel), they actually are palatable when eaten plain. For making jelly or jam, however, you naturally want them to be plump and juicy.

There are actually two species of Oregon Grape on the Island, the other one being the Long-Leaved Oregon Grape (Mahonia nervosa). As their names imply, the Tall Oregon Grape is the taller-growing of the two, while the Long-Leaved Oregon Grape has longer leaves containing many more leaflets. The two also grow in different environments: the Tall growing in open, sunny spots and the Long-Leaved growing as an understory plant in forests.

Of the two, it tends to be easiest to make harvests of the Tall Oregon Grape’s fruits, because it tends to fruit more heavily than the Long-Leaved Oregon Grape.

The inner bark of both our Oregon Grapes is bright yellow, due to the presence of the alkaloid berberine, which has long found traditional use as a yellow dye. Berberine-containing extracts of these and related plants have also been used traditionally for anti-fungal, anti-inflammatory, anti-fever, and other properties. This compound is currently the subject of mainstream medical research; it has already been demonstrated to be therapeutic for diabetes.

The Dewberry, also called the trailing blackberry, is probably the least-known of our wild blackberries. This is most likely for two reasons:

1. They are physically smaller than the more well-known Himilayan (Rubus armeniacus) and Evergreen (Rubus laciniatus) blackberries.
2. They have been outcompeted by these two nonnative species thus are not as numerous, either.

As alluded to in the list above, the Dewberry is our native wild blackberry; the other two ones mentioned are the introduced ones that take over and dominate virtually any vacant space in short order. While its numbers may be somewhat reduced, despite that there is thankfully no shortage of Dewberries in this region.

While it can be easy to find Dewberry plants, finding ones that are bearing fruit can be significantly harder. That is because unlike its introduced relatives (and most plants), Dewberries, like most animals, come in separate male and female individuals. So unless you find a female patch with at least one nearby male patch, you will not be seeing any berries on these. (The Dewberry’s canes tend to root as they trail, so this plant is typically found in large, clonal patches.)

Instead of having giant, ferociously thorny canes that can grow 20 feet or more per year and make thickets 10 or more feet high, the Dewberry is a much smaller and less aggressive plant. As its other name implies, it typically trails low to the ground. While thorny, its thorns are far smaller and thinner than of its two introduced cousins.

I hesitate to mention it, because it might increase competition for the berries I harvest, but the Dewberry is one of our best-flavored berries. It figures in the parentage of the loganberry and the boysenberry, and was bred into these cultivated berries specifically for its flavor.

The fruit is smaller and not borne in the great profusion that it is on our introduced blackberries, so it can be difficult to find Dewberries in quantity sufficient for use in recipes calling for blackberries. I have my secret spots, and have managed to make large enough harvests several times; in each case, the results got rave reviews from all who sampled them.

And before anyone asks: no, I will not be sharing the locations of these spots!

This is not exactly a showy flower; in fact, I believe this is the first time I’ve noticed it in bloom. There are two small purple dots on each bloom which only showed up in the second of the two photos I took.

Here in western Washington, it tends to grow in drier woods. This plant is a member of the Mint Family (Lamiaceae, or if you prefer the classic old family names, Labiatae).

The common name of this plant comes from the Spanish for “good herb,” and was bestowed upon it by the Spanish colonists of California. It was so abundant in the area around what is now San Francisco that this plant was the source of the original name of that city.

The Spanish called it so because of its aroma, which is a mix of minty and savory. A tasty herbal tea can be brewed from its leaves; however, on Bainbridge Island it is probably best to let it be. That’s both because we don’t have very much of it, and because the south-facing coastal bluffs which it favors are also the favored environment of Poison-Oak (Toxicodendron diversilobum).

I use the scientific name Satureja douglasii here because that is the name this plant has historically been known by. Genetic sequencing has thrown the nomenclature of many plants into disarray, and this is one of them. This species was first renamed Micromeria douglasii; now some taxonomists are insisting that the correct name should instead be Clinopodium douglasii.

Until the “gene jockeys” settle their arguments, I plan to stick with the traditional name for this plant (as well as other ones in the same situation). The purpose of a name is to facilitate communication, and names that keep changing tend to by contrast frustrate communication.

The above picture was taken by me last week in Lillooet, BC. There were several large patches of yellow flowers by the road, easily enough to get my attention as a passenger. Their size and color indicated they were probably cactus flowers. I alerted the driver so we could go back, stop, and admire them.

Many are surprised to learn there is wild cactus growing in Canada; my fellow companions on that trip were amongst the surprised. Many are equally or more surprised to learn that the same species also grows wild in western Washington, in the most rain-shadowed areas of the Olympic Mountains. Here is a patch I saw near Sequim earlier this spring:

It shouldn’t really be a surprise that cacti are found in either Lillooet or Sequim, as both locations are rain-shadowed. Lillooet in particular is known for being a dry spot, and being well inland often has just the sort of hot, dry summer conditions that cacti love. Plants don’t care about our preconceived biases or political boundaries; they grow wherever the environment is suitable for them.

The winters aren’t hot or dry, but this species is one of the hardiest and most northerly of cacti. It grows as far north as the Peace River Valley in northeastern BC, a region that can see temperatures colder than -40˚ in the winter.

Its common and scientific names point to how its pads easily become detached from the mother plant, their thorns embedding themselves in the fur, clothing, or skin of unwitting creatures that brush against them. When removed and discarded, they root and create new plants. In this trait, this prickly pear acts more like a cholla. That’s not a huge surprise, as the chollas (genus Cylindropuntia) and prickly pears are very closely related; for many years both were even lumped into the same genus.

Some of my own Opuntia fragilis are getting ready to bloom. I may be interested in plants, but unlike most who are, I’m not very good at gardening. This cactus was the answer to my question: “What could I plant in those window boxes (preferably a native plant) that I wouldn’t kill by forgetting to water or being away and not able to water?”

Those window boxes in question face south and are beneath eaves that serve to keep most rainfall out of them, the perfect micro-habitat for a sun-loving rain shadow plant like this. It felt a little odd dumping the nice potting soil out of them and replacing it with the gravely glacial till (of which I have plenty in my yard) that our local populations of this cactus prefer.

I was hoping to see a Dudleya on my recent quick trip to Southern California (which mostly dealt with family matters, leaving little time for nature). I was lucky and managed to locate one in bloom despite there being a multiyear drought there. (Sorry, no picture of the leaf rosette; it was buried in a dense, low shrub and impossible to get a useful photograph of with the limited equipment I had with me.)

And yes, I know the focus is on the crappy side. Chalk it up to using an autofocus-only compact digicam on a bright day when the preview screen was hard to see in the harsh sunlight.

I’ve been out of town a fair bit recently, so this is a photo that was neither taken on Bainbridge Island nor even does it show a plant that grows here, for the plant depicted above is the Cloudberry, Rubus chamaemorus.

Seeing this flower for the first time was a highlight of my recent trip to BC. The one in the picture is one of the southernmost wild-growing Cloudberry plants in the world, as this plant’s range stops at the bogs of the Fraser River Delta, just north of the 49th parallel. It’s mostly a plant of the arctic tundra, but some populations do wander well south of the arctic in bogs.

Burns Bog has long been a forgotten and neglected part of the Vancouver metro area. There’s now efforts to preserve the parts of it that haven’t been drained and converted to other uses, but facilities for visitors are still very limited and not easy to find. Those interested in visiting a part of it that’s open to the public on their next trip to Vancouver can find the driving directions here.

Why do we see plants of the arctic tundra in peat bogs? It turns out that bogs mimic many of the soil conditions that form in the arctic. Like the arctic tundra, whose soil is prevented from draining by permafrost, bogs contain highly acidic waterlogged soil.

Why is Cloudberry found in these bogs, but not in ones just slightly further south, which have almost identical soil and environmental conditions? My best theory so far is that it has to do with migrating birds: before it was urbanized, the Fraser Delta was a huge complex of freshwater and tidal wetlands that served as a major wintering area for waterfowl, and at least one bird over the millennia arrived with a Cloudberry seed riding somewhere on it or inside its gut. Smaller peat bogs to the south failed to serve as major attractors of wintering waterfowl and thus never had this plant introduced to them.

The bog at IslandWood here on the island has no Cloudberry, but it does have a lot of Labrador Tea (Ledum groenlandicum), a plant whose common name references one northerly region and whose scientific one references another (Greenland), thus revealing its status as an arctic tundra plant.

Vanilla Leaf (Achlys triphylla) is now in full bloom. This distinctive forest-floor plant has leaves with three leaflets that arise directly from underground stems. Its tiny, white flowers arise in dense spikes from those same underground stems.

As its name implies, the leaves of this plant have a faint scent vaguely resembling vanilla. The odor becomes stronger if you gather a bunch of leaves and let them hang upside down to dry. In fact, I personally am not able to discern any vanilla odor from this plant unless its leaves are dried. For many years, it was a mystery to me why this plant has the common name it does.

Bundles of such dried leaves can be hung near doors and windows as an insect repellent; they have been used as such since pre-contact days by Native Americans. I have not personally tried it yet, but it is also reported that rubbing the fresh leaves on exposed skin can also act as an insect repellent.

You may be surprised to learn that this plant is a close relative the Oregon-Grape (Mahonia spp.). Both are in the barbarry family, Berberidaceae.

The Large-Leaved Avens (Geum macrophyllum) is mistaken as some sort of buttercup (Ranunculus sp.) by many. It’s an understandable mistake, as buttercups tend to have the same five yellow petals (albeit far glossier) as this avens does. The foliage of this plant also somewhat resembles the foliage of many buttercup species. Completing the deception, the Large-Leaved Avens typically grows in the same sort of moist, wooded areas that is favored by both a native and an invasive buttercup.

Of those two buttercups, the one that starts blooming at the same time as this avens has much smaller flowers. The other buttercup starts blooming later, and although its flowers are larger, it has a spreading habit that this avens lacks, and moreover is not typically as tall as the Large-Leaved Avens, either.

Despite appearances, this plant is not even closely related to the buttercups. The latter are in the buttercup family (Ranunculaceae); the Large-Leaved Avens belongs to the rose family (Rosaceae). This plant and our woodland buttercups have evolved to have a similar form because they grow in similar environments, and are thus subject to similar pressures of natural selection, a process is known as convergent evolution.

By late summer, this avens’ fruits will have ripened into burs that stick to clothing and fur.

The Red Elderberry (Sambucus racemosa) bushes are in bloom. The warm days we are having are really making things go fast. I took this picture just a week ago when it seemed the blossoms were just opening, and already they seem more than half-done.

Elderberry flowers tend to get ignored by many, or at least not much talked about. That’s always been a mystery to me, as they are quite ornamental. The flowers occur in pyramidal (not flat) clusters and ripen into shiny red fruit.

This is our native elderberry. It has a reputation for being poisonous, which is mostly true. The exception is that the ripe fruits can be eaten provided they are cooked thoroughly first. I have yet to try them, so cannot offer my opinion as to how good (or otherwise) they taste. Birds relish the fruit and in so doing disperse the seeds of this shrub.

Those who travel to the east slopes of the Cascades (or to select areas of the east slopes of the Olympics) might be familiar with the related Blue Elderberry (Sambucus mexicana or Sambucus cerulea), a shrub or small tree that bears choice fruit. The Blue Elderberry’s flowers resemble those of the Red Elderberry, but occur in large flat (never pyramidal) clusters. As its name implies, the ripe fruit is covered with a bluish waxy bloom.

The Blue Elderberry is a close relative of the European Black Elderberry (Sambucus nigra); and like that elderberry its fruits are edible and its flowers can be used to make syrups or tea.
