Mountain Plants of the Western Cascades

While the center yellow lines were painted by a road crew, Mother Nature created the line along the edge of the road with a bright yellow ribbon of gold stars. They are also sprinkled all over the cliffs along Hills Creek Reservoir.

A little rove beetle(?) has gotten completely covered with pollen from the tiny flowers of skunk cabbage (Lysichiton americanus).

I almost always start my botanizing year with a trip in March to the Rigdon area in southeastern Lane County. With the cold, wet weather of March and April and the lateness of the wildflower emergence, I didn’t get out there until April 26! As I suspected, the wet spring was ideal for gold stars (Crocidium multicaule), and most everything was at least 3 weeks later than usual. Here are a few highlights.

Glaucous spring beauty (Claytonia exigua ssp. glauca) is a diminutive, early annual. While I usually see it on mossy rocks, this population grows in a mound of dirt in the ditch below the cliffs.

After being mistakenly cut down several years ago, the Fremont’s silktassel (Garrya fremontii) by the bridge at Hills Creek Reservoir has at long last recovered enough to put its energy into flowers! A dioecious species, this one is a male with longer tassels.

The skunk cabbage swamp hidden behind Everage Flat Picnic Area was one of the highlights of the day. The flowers were fresh and fragrant, and the leaves hadn’t yet started to give off the skunky odor they are known for.

California mistmaiden (Romanzoffia californica) is distinguished by its hairy, tuber-like bases. The little axillary bulbils that are typically present in this area also show the hairy bases. They drop off and form large colonies in the right spot, usually cliffs or rocky slopes.

This wasp enjoyed the little flowers of California mistmaiden. There were also small bees visiting some of the gold star flowers. I was disappointed to see only a few butterflies (a red admiral, a propertius duskywing, and a handful of California tortoiseshells), but as I’d only seen one butterfly so far this year and just a few days before, it was great to see any. I can’t wait for more of them to emerge from their various stages of overwintering.

The rocky bluff next to the Sacandaga Campground was also covered with gold stars.

Looking south to Calapooya Mountains from the large (and steep!) lower meadow, you can see snow still along the crest. The large white area to right end is Bristow Prairie. While I love seeing snow lingering at the end of May, I hope it will have melted by the time I have to lead a hike there later in the month.

As I drove along the reservoir in the morning, a large butterfly caught my eye, so I pulled over immediately and waited for it to return. The gorgeous tiger swallowtail rewarded me by landing and sitting perfectly still on a stunning lupine. Calendar shot for sure!

Since there is still some snow at higher elevations, and the rain is fueling great flowers down low, on May 31, I decided to head to the large lower meadow off the Youngs Rock trail. I went down there twice back in 2016 (see Exploring Meadows Below Youngs Rock) but hadn’t returned since. After my usual stops along Hills Creek Reservoir to see the gorgeous paintbrush (Castilleja hispida and possibly pruinosa), I stopped at the bathroom by the bridge and noticed a lot of activity under the bridge. When Nancy and I stopped there the week before (see Spring Again at Coal Creek Bluff), I was surprised at the absence of swallows since we had seen some tree swallows along the cliffs. But on this trip, there were numerous swallows, some tree swallows but mostly cliff swallows. You can recognize cliff swallows by their buffy back and the creamy spot on their head and nape. Both tree and cliff swallows have a much shorter tail than barn swallows. They appeared to be rebuilding their nests under the north side of the bridge. Or maybe they start new ones every year, I don’t know. I guess there’s not enough room left in my brain to learn about birds after studying plants and butterflies so much! I spent a while watching them and listening to their unusually squeaky chattering—definitely different from the tree swallows that live in my meadow. Read the rest of this entry »

Looking north across the slope to Moon Point and Youngs Rock. I hadn’t seen such a pretty show of monkeyflower on my past visits.

On Wednesday, May 25, Nancy Bray accompanied me on a trip to the place I named “Coal Creek Bluff.” I had heard that the Forest Service would be further decommissioning the old Road 210 that I use to access the site to protect Coal Creek from further erosion. I wasn’t sure what this entailed, so I was anxious to find out if I would still be able to access this lovely spot, one of our purple milkweed (Asclepias cordifolia) sites in the Rigdon area. The last time I was there (in 2020, see Followup Milkweed Count at Coal Creek Bluff), I couldn’t make it to the last place you can park before a big washout on the old road. I managed to scratch my brand new car trying to turn around after coming upon a fallen tree. So this time, I just decided to park at the old gate where there is a large area to turn around and do the extra walking. I was surprised to find the road completely clear all the way to the final parking area. Darn! We could have shortened our walk. Next time I’ll know. Read the rest of this entry »

The first California tortoiseshell to land on my hand

This very odd filbert (Corylus cornuta var. californica) catkin caught my eye near the river. Normally the female flowers with their red-violet stigmas are in a small cluster that is separate from the long, dangling male catkin. But this inflorescence had several females mixed in with the males. What happened here?

While it wasn’t a terribly difficult winter weatherwise (though not nearly enough rain), it is always a joy to see the first flowers of late winter and spring. And with them, the reappearance of the first butterflies. On Tuesdays, I often have meetings for my job with OregonFlora, but this past week, my meeting was postponed for a day. That turned out to be very fortunate as Tuesday was the most beautiful day of the week: clear and sunny and the first day of the year to reach 70°. I took advantage of it to head out on what has become my annual first botanizing trip of the year out to Hills Creek Reservoir and the Rigdon area along Road 21. I stopped at all my usual haunts. First along the reservoir to see the gold stars (Crocidium multicaule) blooming. It hasn’t been wet enough for an outstanding year, but they are still such a welcome sight. The paintbrushes (Castilleja) are sending up new leaves that are noticeably reddish. The Sierra gooseberry (Ribes roezlii) was just barely in bloom.

This handsome madrone (Arbutus menziesii) is growing on Rabbitbrush Ridge. It was laden with bright red berries. Beneath it is an unusually colorful, low-growing Oregon white oak (Quercus garryana). In the foreground are the silvery stalks of rubber rabbitbrush (Ericameria nauseosa). The species’ abundance here elicited my name for this steep, rocky ridge.

One goal of my outing was to come home with seeds of the very late-blooming autumn knotweed (Polygonum spergulariiforme). I have a small population on my property that I’m working on expanding. Anything still blooming at the end of October is worth having, no matter how small its flowers.

With the days getting shorter and colder and the damp days increasing (I’m not complaining—after this summer I’m so thankful for wet weather!), I was looking for a dry and, hopefully, sunny day for one last trip into the mountains before winter really sets in. While the sun was playing peek-a-boo behind the clouds all day, at least it was dry on October 31, and I was able to head out to the Rigdon area. I decided to stay at fairly low elevation given the clouds and limited time and headed for Grassy Glade, stopping along the way for anything that looked colorful or interesting. And once I got to Grassy Glade and walked down to the end of the road past the meadow, I had just enough time to head down to “Rabbitbrush Ridge” where the last flowers of rubber rabbitbrush were still in evidence. It was a pleasant if unexciting day—hopefully enough to sustain me until the flowers reappear in February and March. I didn’t expect there would be much to photograph, but as you can see, I found plenty of interesting plants on my end-of-season trip. Read the rest of this entry »

Jenny studying the plants in the still-green seep along the edge of the west meadow. The lush shrub at the top of the photo was a very healthy poison oak!

Back in February, I was invited to a Zoom meeting set up by Walama Restoration and the Middle Fork Ranger District to discuss ongoing restoration projects in the area and further work on purple (or heartleaf) milkweed (Asclepias cordifolia) and monarchs (if their population bounces back) in the Rigdon area. At that meeting, I learned that last summer the district hired some surveyors to check out special habitats (I think that includes anything that isn’t forest!) on the west side of Hills Creek Reservoir and the Middle Fork of the Willamette. They surveyed a number of south-facing openings that I’d seen on Google Earth but never explored. I was very excited to hear that they found two new populations of milkweed! And these were farther north than any of our other sites, making them the new northern boundary of its range. Jenny Moore, the current district botanist, didn’t know much more about the sites or the milkweed itself there, so we discussed going up there together to see them for ourselves once the milkweed started blooming.

After seeing the milkweed starting to flower at Big Pine Opening a few weeks earlier (see Relaxing Day in Rigdon), I figured it was time. The weather was supposed to get hot again, so I was happy that Jenny was able to go out with me on Friday, May 28 before it got too hot for a steep bushwhack up low-elevation, south-facing, rocky meadows around 600′ above the road.

Beautiful spreads of woodland phlox (Phlox adsurgens) bloomed along the edge of the both the paved road and the gravel one we walked on.

On Sunday, May 9, I went for my first outing in almost a month—just too much to do at home, and the drought discouraged me from going to my favorite seepy spots that I’d planned on, like Deer Creek. I was really happy to be able to go out with my friend John Koenig, whom I hadn’t seen since last summer. Being vaccinated now is such a relief, and it is wonderful to safely hang out with others who are also vaccinated (if you’re hesitating—don’t!). We decided it might still be too early to try to go to higher elevations, even with all the warm weather, so we headed down to Hills Creek Reservoir and the Rigdon area to check out some of our favorite haunts. We had some vague plans but mostly just played it by ear, stopping wherever looked interesting. We ended up spending lots of time watching butterflies. We also had to warm up our “botany muscles,” trying to remember forgotten names.

At Everage Flat, we spent quite a long time watching butterflies on the Pacific dogwood flowers. This echo azure is enjoying the fresh flowers in the center of the showy bracts.

After a look at the gorgeous silvery lupine (Lupinus albifrons) at the north end of the reservoir and a brief stop to admire the blooming paintbrush on the cliffs along the reservoir, I pulled into Everage Flat Picnic Area (just south of the intersection of Youngs Creek Road 2129) as it occurred to me that we should see if the Howell’s violet (Viola howellii) was still in bloom. I expected it to be a very quick stop, so I even left my (all-electric) car on. But upon seeing that the large Pacific dogwood (Cornus nuttallii) in the sunny center of the picnic area was in perfect bloom and appeared to have butterflies flying around it, I parked the car for real. Our 2-minute stop turned into a 2-hour one! Read the rest of this entry »

From the west opening on the bluff next to Sacandaga campground, you can see the snow on the area that burned in the 2009 Tumblebug Fire.

I was so happy to see so many handsome male catkins on the Fremont’s silktassel (Garrya fremontii) next to the bridge and boat ramp at Hills Creek Reservoir. This lovely native plant was accidentally cut down by a Forest Service crew while working on nearby weedy shrubs a few years back. It has been slowly recovering ever since.

One of the best benefits of having a remote job doing layout and design is that I set my own hours. Or in other words, I can usually play hooky when I feel like it! When I saw that the forecast for Oakridge was supposed to be in the 70s (!) on Wednesday, March 31, I dropped everything to see how things were progressing down in Rigdon. And after spending several weeks focusing on butterflies while preparing my slide show on “Favorite Plants of Butterflies of the Western Cascades” for the North American Butterfly Association and the Middle Fork Willamette Watershed Council (you can view the recording here), I couldn’t wait to spend a day with some butterflies.

Our paintbrushes hunker down for the winter, not quite going totally dormant. Now the new shoots have begun to grow, bringing forth the promise of those gorgeous red flowers in a few months. This plant growing on the cliffs along Hills Creek Reservoir might be frosted paintbrush (Castilleja pruinosa), but the paintbrushes in this area are quite variable.

One of the small creeks at Many Creeks Meadow was running well.

Just a short post today about my first trip of the season. Sad to say, I’m already way behind on posting as the trip was a week ago, on March 3rd. As always, I started the season with a look at many of my favorite spots along Road 21, in the Rigdon area south of Oakridge. Things were just starting, with only a handful of species in bloom, but it was a gorgeous sunny 60° day, so I enjoyed it thoroughly. In bloom were gold stars (Crocidium multicaule), meadow nemophila (Nemophila pedunculata), snow queen (now with a new name: Veronica regina-nivalis), white alder (Alnus rhombifolia), slender toothwort (Cardamine nuttallii), Hall’s lomatium (Lomatium hallii), and the very first Sierra gooseberry (Ribes roezlii) flower.

This photo of the view east was taken from about the same spot as the ones I used in my previous two reports about Maple Creek Meadow—why break tradition? The little opening on the nearest ridge is Rabbitbrush Ridge where I went the previous week (see More Exploration Near Grassy Glade) and which also has purple milkweed, rubber rabbitbrush (Ericameria nauseosa), northern buckwheat, and bluefield gilia, all seen here.

With the forecast predicting warm summer weather on the way, I figured it might be my last chance to get out to see the peak bloom of purple milkweed (Asclepias cordifolia) at lower elevation meadows without roasting. I had been wanting to return to what I named “Maple Creek Meadow” as I’d only been there twice before: first on a hot day in July (see Another New Milkweed and Monarch Site!) when most things were finished and the following year on a cloudy day in May (see Surveying Milkweed at “Maple Creek Meadow”) when many plants were just starting. So I was due for a sunny but cool day in the middle of the season and headed out to the Rigdon area of southeastern Lane County on June 17.

Two caterpillars eating flower stalks of rose checkermallow. Apparently, their color depends partly on what they are eating. I think both are gray hairstreaks (but correct me if you think otherwise!).
