Beautiful fall color in the thickets of oval-leaved viburnum that grow on the slopes of Mistmaiden Meadow

In the wetland along Road 140, there were still trillium-leaved wood sorrel (Oxalis trilliifolia) in bloom. Its leaves are similar to the far more common Oregon wood sorrel (O. oregana), but the flowers are in clusters and bloom later, and they grow in very wet spots.

Thank heavens for the wonderful rain on August 31! I had been so worried we’d have to wait until October for some decent rain, like last year. We got 3/4″ of an inch at my house, probably more in the mountains. That was followed by almost of week of cool, cloudy weather, and even a little more rain. It tamped down the fires, reduced the smoke, and made it much easier for the firefighters to contain the fires. In fact, The Forest Service reduced the south end of the closure area near the Bedrock Fire. That meant I could finally return to “Mistmaiden Meadow” near Sourgrass Mountain, where I had hoped to survey throughout the flowering season. My last trip had been on July 7 (see Fourth Trip of the Year to Mistmaiden Meadow), and I’d planned to go back on July 23 until I realized the Bedrock Fire had started the day before. I had missed two whole months, so I was really anxious to get back. On September 6, the first nice day I had free after the welcome cool and rainy weather abated, I headed up there.

Thompson’s mistmaiden was abundant on the seepy parts of the slope (which is most of it!).

I was surprised to find this checkerspot caterpillar wandering around some wholeleaf saxifrage (Micranthes integrifolia), which is definitely not a host food plant. Neither is Thompson’s mistmaiden, the little flowers popping up among the saxifrage leaves. There must have been some paintbrush nearby.

My last report of 2022 was about two late-season trips to hidden meadows in the area near Saddleblanket and Sourgrass mountains (see Exploring Two New Meadows). I was really excited about getting to see the meadows in bloom this year, especially the large one off of Road 140 on the west flank of Sourgrass Mountain. Having already been to nearby Tire Mountain (see Early Season at Tire Mountain), I had seen the lush green meadow from the north side of the ridge, and I knew the road was clear to Windy Pass. On May 30, Nancy Bray accompanied me, hoping for a first look at the early spring flowers in the big meadow. We had also planned to try to get to the other meadow and nearby Elk Camp and Nevergo Meadow, just a few more miles to the north, but we were stopped by a single patch of snow blocking Road 140. Luckily, we were only half a mile from the first meadow, so we walked the rest of the way up the road, which was clear of snow except in some ditches. There were still some glacier lilies (Erythronium grandiflorum) and fresh western trilliums (Trillium ovatum) in the freshly melted-out ditches and road banks on our way up.

I do hope that some of the beautiful purple milkweed will be in bloom on our upcoming trip to Grassy Glade!

Beautiful harsh paintbrush (Castilleja hispida) blooms along the road by Hills Creek Reservoir.

On Saturday, May 27, I headed out to the Rigdon area to plan the field trip I’m leading for the Native Plant Society of Oregon Annual Meeting the following Saturday. I want to give people a taste of the interesting plants in this area that are more common to the south, especially the lovely purple (or heartleaf) milkweed (Asclepias cordifolia) that I’ve written about so many times. I’ve been crossing my fingers that we will see some in bloom somewhere, but with the crazy shift in weather this spring, it’s hard to anticipate how the plants are going to react. There are lots of great places in the Rigdon area, but I wanted to know which would work best for our non-trail field trip.

I drove straight to Grassy Glade and parked along the side road near the beginning of the meadow. I did a quick spin through the meadow, which was half baked and half moist. On the road in, I had noticed some of the potholes were partly filled with water. Obviously, some of the thunderstorms that I’d heard had occurred out here had blessed the area with some much-needed moisture—there hasn’t been a drop for almost three weeks at my house. My guess is that some of the meadow had already dried out before the rain, while the moister parts had been refreshed before the annuals died. Spring gold (Lomatium utriculatum) and many species of clover (Trifolium spp.) had started along with the cute narrow-leaf owl’s clover (Castilleja attenuata). Read the rest of this entry »

The photographic highlight of the day had to be this cluster of trilliums visited by a pale swallowtail. The butterfly was as enthralled as we were and stayed for at least 10 minutes, allowing me to get over 40 photos from every angle.

For months, I’ve been working on and off to finish editing and doing the layout for the Saxifragaceae treatment for Volume 3 of the Flora of Oregon (I finally finished it so I felt I could take a break to write this report, however late). I had enough space to add a couple of illustrations and wanted to do two of the more interesting species, rusty saxifrage (Micranthes ferruginea) and Merten’s saxifrage (Saxifraga mertensiana). Our lead artist, John Myers, does most of the illustrations, but he has so many to do right now that I’m contributing a few of the species I’m familiar with.

Both these species are unusual in that they are able to produce asexually by vegetative offsets. Rusty saxifrage has tiny plantlets in the inflorescences that replace most of the flowers except the terminal ones. These drop to the ground and form colonies of clones beneath the mother plant. Mertens’ saxifrage often produces clusters of red bulblets in the inflorescences. Like the rusty saxifrage, these replace the lower flowers. From what I’ve read, it produces these bulblets in most of its range. In the Western Cascades, however, I’ve only seen them in a few populations. One of these is along Coal Creek Road 2133 on the way up to Loletta Lakes. Read the rest of this entry »

From where the trail first reaches the ridge, there’s a good view of the Three Sisters with fresh snow.

One of the few butterflies I saw, this orange sulphur was sitting on the silvery leaves of Oregon sunshine (Eriophyllum lanatum), while the gorgeous purple leaves are those of sticky cinquefoil (Drymocallis glandulosa). The little flower on the left is Cascade knotweed.

Technically autumn started on September 22 this year. But for all intents and purposes, fall started with the first real rain on September 18. What a relief!! After the seemingly endless hot and smoky summer, following an unusually hot, dry spring, it was hard to remember what rain sounded like. We got at least 2 inches at my house; the patter of raindrops on the skylight above my desk was music to my ears. And finally, with the fires no longer spewing out smoke, I could go out again! It had been four weeks since I’d managed to sneak in a half day seed-collecting trip to Cloverpatch on a relatively clear day. I could hardly wait to get up in the mountains. On Monday, September 20, it was dry—or at least it wasn’t raining. I headed up to Lowder Mountain under clear blue (not dirty brown!) skies. Everything was still pretty wet from the rain, and it was quite cold up there when I stepped out of the car (not that I’m complaining!). My original plan was to bushwhack around Quaking Aspen Swamp, but not wanting to be drenched, I decided staying on the trail would be wiser and headed up Lowder Mountain instead, both trails starting from the same spot.

Springtime means skunk cabbage and mountain buttercups blooming in the lovely wetland at the bottom of the large meadow on the south side of Patterson Mountain.

Still anxious to see early mountain flowers, yesterday, May 23, I headed up to Patterson Mountain. In spite of it being my 29th trip up there, I took a wrong turn on the way up. Last year they started heavy thinning of the surrounding forest, and the main Patterson Mountain Road 5840 is hardly recognizable with the reopening of many old side roads. At one point, both sides of a “Y” in the road look equally well used and the road sign for the side road is in the middle. Hopefully, I’ll remember from now on that the right turn to take is the right turn! Read the rest of this entry »

One of the beautiful madrones (Arbutus menziesii) that grace the bluff. Coal Creek can be seen cutting through the forest down below.

From lower down the slope, I got a peek-a-boo glimpse of the small waterfalls upstream along Coal Creek. Unfortunately, a closer look would require climbing down some very steep banks.

Saturday, May 9, was a beautiful day but around 80°—much hotter than I’m used to this time of year. I had hoped to get up to a high enough elevation to be a little more comfortable, and I was really hoping to see the very early mountain flowers. My plan was to try to get up to “Heavenly Bluff” to see the Siskiyou fritillary (Fritillaria glauca), a very early bloomer. I hadn’t been there for 6 years. If I couldn’t get that far, I would go to Bearbones Mountain, which I would pass on Road 5850. It’s another site for the fritillary, though much less floriferous. Unfortunately, right after I turned onto Road 5850, I came upon a number of fallen trees. It was another 3 miles or so to get to Bearbones, so I was not going to add over 6 miles of road to my hike. A little snow in the ditch also made me wonder if there might still be some snow blocking the road farther ahead even without downed trees. The shady section of road on the north side of Spring Butte seems to hold snow longer than the rest of the road. Read the rest of this entry »

On the way up, we stopped for lunch at the top of the quarry. John’s proximity to the edge of the cliff gave me the willies, so I sat farther back.

On October 16, it was a beautiful clear day, and John Koenig and I headed up into the Calapooyas for one last chance to visit this wonderful area before winter set in. We headed down Road 3810 that runs along the west side of Balm Mountain. In the past, John and I had planned a trip to find a way to hike up to the south end of Balm Mountain (which is really a long ridge) through some meadows we could see on the aerial images. All my previous trips were approached from the north end of the mountain. We tried several times to get down to the end of the road in the past, but trees blocked it well ahead of where we needed to start (see Another Look at Aspen Meadow and Bradley Lake). On a previous visit to what we call Aspen Meadow, a wetland along Road 3810, we had driven down the road and discovered the trees were finally cleared, but there was a huge washout—one that I can’t see ever being fixed—about a half mile from where it used to dead end.

A last remaining snow bank in the wetland. The mountain shooting stars (Dodecatheon jeffreyi) and marsh marigold (Caltha leptosepala) were still in bloom, so it was probably too early for the Sierra Nevada blues to be out yet.

It was very odd to see a number of cliff paintbrush (Castilleja rupicola) blooming along the edge of the gravel road right beside the wet ditch and moisture lovers such as brook saxifrage (Micranthes odontoloma).

On June 19, John Koenig and I took a trip up Coal Creek Road 2133 to see what was blooming in the high country. This is one of our favorite areas. But first, we stopped by Monarch Meadow to see if there was any activity. There were no monarchs flying around, but we saw a handful of eggs. Then we stopped at many wonderful spots along Coal Creek Road to look at plants and butterflies before ending our day in the wetlands near Loletta Lakes. Thickening clouds right above us along the crest of the Calapooyas kept the butterflies down at the top, but we saw plenty on the way up. Things were still pretty early up there, and we even saw a few lingering glacier lilies (Erythronium grandiflorum) and some snow. Here are a few photographic highlights.

John exploring the steep slope above Medicine Creek Road. A few purple milkweed plants can be seen in the foreground.

Last year, while camping on the North Umpqua, Nancy Bray and I explored the first few miles of Medicine Creek Road 4775, just east of Eagle Rock Campground (see A Week of Monarchs and Milkweed Day 2 and Day 3). It was the only site for purple milkweed (Asclepias cordifolia) listed on the Oregon Flora Project Atlas. We had a wonderful time looking at milkweed and watching monarchs and other butterflies, and I could hardly wait to get back this year to see the earlier blooming plants.
