Late Start to 2023 Botanizing

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.
2022 Botanizing and Butterflying Season has Begun!

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.
On the Menu at the Butterfly Café

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.

2021 Botany Season has Begun!

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.
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.

More Exploration Near Grassy Glade

The most floriferous spot at Rabbitbrush Ridge is a small draw next to the dike. No doubt this area funnels most of the surrounding moisture to the mass of northern buckwheat (Eriogonum compositum), frosted paintbrush (Castilleja pruinosa), varifleaf phacelia (Phacelia heterophylla), bluefield gilia (Gilia capitata), ookow (Dichelostemma congestum), and Oregon sunshine (Eriophyllum lanatum).

Candelabrum monkeyflower is a delicate annual that prefers openings among shrubs where there’s little competition.
On Wednesday, June 10, we had a day off from the rain (not that I’m complaining about rain in June anymore!), so I took advantage of it to head back to Grassy Glade and check out one more opening I hadn’t been to yet and see how the purple milkweed (Asclepias cordifolia) was doing.
First I made a few stops to collect seeds: silvery lupine (Lupinus albifrons) was ripening on the north side of Hills Creek Reservoir, and there was still some seed of Hall’s lomatium (Lomatium hallii) along the cliffs west of the reservoir. I also got a good collection of seeds of the annual miniature lupine (Lupinus bicolor), which I’d spotted growing abundantly along the road right under the guard rails. In this same area, the paintbrush (a mix of Castilleja hispida and C. pruinosa) was still blooming as was the Oregon sunshine, including a lovely pale yellow-flowered plant I’ve watched for years. I’ll be back for seeds of those later in the summer—Castilleja blooming in an area I’m restoring on my property are the progeny of these plants, growing successfully in mats of Oregon sunshine, some of which were also grown from seed collected here.

Early Trips to Rigdon
It’s been a busy winter and spring with a lot of unexpected setbacks—snowstorm and broken wrist among the worst. The snow’s long gone, and the wrist is healing, but I’m still not caught up on everything I had hoped to do in the last few months. While I haven’t been out as much as usual, I did make it out to Rigdon several times, so I’ll share some photos from those early spring trips.
March 17

My friend Karl hadn’t seen the big show of gold stars (Crocidium multicaule) along Hills Creek Reservoir, so we headed out there on March 17. We only made it out as far as Big Pine Opening because of all the downed trees and remnants of snow on the road, but the show along the reservoir was beautiful.
Very Early Visit to Monarch Meadow
With the continued spring-like weather, Sabine Dutoit and I wanted to head out to Road 21 and Hills Creek Reservoir for our annual ritual to see the gold stars (Crocidium multicaule) in bloom. Seeing the first show of floral color really starts the year off right. The fact that it is so much earlier than usual worries me, but for now, I’m trying to just enjoy being able to start botanizing in February. They were much farther along than last week when John Koenig and I stopped to check, but they still have a long way to go before they are at peak bloom. Hopefully, we’ll get some rain soon to keep them going. Read the rest of this entry »
Further Low-Elevation Meadow Exploration
After the September rains finally put an end to the fires and cleared out the smoky skies, I was anxious to get back outside after being trapped indoors by the smoke for so much of late summer. I had hoped to look for more meadows and open areas in the Rigdon area, southeast of Hills Creek Reservoir. I knew it would be hard to spot purple milkweed (Asclepias cordifolia) plants so late in the year, but I could at least assess the quality of the areas and the potential for milkweed or other interesting plants. With the flowers pretty much done for the season, it didn’t seem worth the many miles of gravel to get up to high elevations, so exploring more low-elevation meadows was the perfect goal.

Ground rose (Rosa spithamea) is generally less than a foot tall. It is distinguished from our other roses by its chubby, gland-covered hips. There’s quite a bit of it at Mutton Meadow.
On September 25th, Sheila Klest and I went to Monarch Meadow to see if there was any milkweed seed left and to collect any other seed of interest. The milkweed stems had mostly collapsed and there were very few intact seed capsules, but Sheila was able to bring home a bit of seed to try growing at her native plant nursery, Trillium Gardens. I was glad I had already gotten some for myself back in July (see Late Season Visit to Monarch Meadow) when they were just starting to ripen. Some sticky birdbeak (Cordylanthus tenuis) was still in bloom, and there was an unusually deep pink form of autumn willowherb (Epilobium brachycarpum) in flower in the meadow but little else. After we collected some seeds of grasses and purple and diamond clarkia (Clarkia purpurea and C. rhomboidea), we headed over to nearby Mutton Meadow. There we hunted around until we found the bright red hips of ground rose (Rosa spithamea) among the grass. They had bloomed well and the hips were perfectly ripe, so we both collected some hips and a few cuttings. I hope I’ll be able to grow this charming little rose. Read the rest of this entry »
Hidden Meadow Reveals a Thrilling Secret
In November of 2012, I went exploring down along Rigdon Road 21 southeast of Hills Creek Reservoir, an area I spend a lot of time visiting, as readers of this blog no doubt have noticed. There’s a small old quarry between Campers Flat campground and Big Pine Opening. I thought I’d see what was in the rocky area up top. The woods were fairly open so I continued up the ridge and popped out in a rocky meadow. While it was well past blooming season, I enjoy “forensic botany”—trying to identify species in various states of decay or at least past flowering. I saw some saxifrages rejuvenated by fall rains, a flower or two left on the late-blooming fall knotweed (Polygonum spergulariiforme), and evidence of bluefield gilia (Gilia capitata). But what really excited me was a few clumps of dried stalks with old capsules filled with silk-topped seeds—a milkweed! Read the rest of this entry »
Exploring the Meadows by Hills Creek Dam
A couple of weeks ago, Sabine Dutoit and I spent a little while along Kitson Springs Road 23, just east of the dam on Hills Creek Reservoir (see Late Start to a New Year of Botanizing). I hadn’t ever been to several meadows hidden from the road, so I decided that would be a good trip to do May 8 after getting a late start getting out in the morning—no gravel driving and relatively close to home.
