Mountain Plants of the Western Cascades

Rosy plectritis paints the hillside pink as Daniel and Angela climb back up “Mistmaiden Meadow.”

Bramble green hairstreaks are really hard to tell from Sheridan’s green hairstreaks; the former has less green on the underside of the forewing and less conspicuous white markings. The best way to tell is to look around for the host food plant as they don’t travel very far from it. The road here is lined with big deervetch (Hosackia crassifolia), the main host food plant of the bramble. Sheridan’s uses buckwheats, none of which grow there. This is where a botany background really helps in learning about butterflies.

Continuing my periodic surveying of what I’m now calling “Mistmaiden Meadow,” the steep meadow on the west flank of Sourgrass Mountain, I headed back up on June 25. This time I was accompanied by fellow NPSO member Angela Soto and her partner, Daniel. My plan was pretty much to follow what Sheila Klest and I did a couple of weeks before (see Shooting Stars are Stars of a Great Day), going to Mistmaiden Meadow and then on to Elk Camp and Nevergo Meadow. Before we even got to the meadow, we had to stop for a small roadside wet spot on Road 1912 when I spotted devil’s club (Oplopanax horridus) out of the corner of my eye. This striking spiny shrub is not that common in southern Lane County, so I don’t see it too often. I’m not sure how I missed it on my previous two trips, although it probably hadn’t leafed out on my first trip this year (see Early Look at Meadow on Sourgrass Mountain).
This spot was just before the intersection where we turn left onto Road 140. Read the rest of this entry »

As soon as I arrived at Many Creeks Meadow, I spotted this pale swallowtail nectaring on the first mountain thistle (Cirsium remotifolium) flower heads.

I believe this is a Hoffman’s checkerspot—or maybe it’s a northern—I still can’t sort them out!

Although I’d already been to Grassy Glade twice this year (see NPSO Trip to Grassy Glade and Planning Trip to Grassy Glade), I hadn’t seen the purple milkweed (Asclepias cordifolia) in bloom yet. On June 21st, I headed back out to Rigdon to stop at some of my favorite low-elevation spots. I started the day at “Many Creeks Meadow,” hidden away just a little way up Youngs Creek Road 2129. There were still patches of moisture to keep the wildflowers and butterflies happy. The showy tarweed (Madia elegans) was quite lovely, and there were some Oregon geranium (Geranium oreganum), narrowleaf mule’s ears (Wyethia angustifolia), and rosy plectritis (Plectritis congesta) still in bloom. I had hoped to find ripe nutlets of Pacific hound’s tongue (now Adelinia grandis) as this is one of the best places I know to find it. Although a number of inflorescences had been eaten, there were still plenty of nutlets to collect, so I was off to a good start to the day. Read the rest of this entry »

The gorgeous mountain cat’s ears attracted cedar hairstreaks.

Several Lorquin’s admirals were among the butterflies visiting the dogbane patch.

One of the field trip sites for the recent Native Plant Society of Oregon annual meeting was Castle Rock. It’s a relatively low-elevation rocky knob near Cougar Reservoir. When I checked the list of all my hiking trips, I discovered I hadn’t been there in 10 years. I’m not sure why it fell off my radar because I used to go every year. After so many weeks without rain, I figured it might be really dry and not very interesting, but I decided to check it out anyway, and I’m so glad I did. On June 16, I headed to Cougar Reservoir first. I was surprised there was still water dripping down the cliffs near the dam and into the concrete ditch where there were some tadpoles swimming around. That was also a surprise. I’ve been seeing a few little black and white moths lately, Macculloch’s foresters (Androloma maccullochii), but here they were abundant, nectaring on lots of flowers but especially the abundant weedy daisies (Leucanthemum vulgaris). I was also able to get seeds of Scouler’s valerian (Valeriana sitchensis var. scouleri) a little farther down the road. On my way back from the reservoir, I passed a strip of spreading dogbane (Apocynum androsaemifolium) growing under the railing—a terrible spot to take photos with cars going by but worth it for all the butterflies and moths.

The population of the seep-loving beautiful shooting star was more gorgeous than I had imagined in “Mistmaiden Meadow.”

Did it just snow? Nuttall’s saxifrage coats the rocks at “Mistmaiden Meadow.”

I was really anxious to get back to the steep meadow on the east side of Sourgrass Mountain after my first trip of the season (see Early Look at Meadow on Sourgrass Mountain). Exactly two weeks after the first trip, on June 13, Sheila Klest and I went to see what was in bloom. We weren’t disappointed. It was even prettier than we expected. As soon as we stepped out into the upper part of the slope, we were greeted with a sweep of pink rosy plectritis (Plectritis congesta). There was much more moisture than there had been at nearby Tire Mountain the week before (see NPSO Annual Meeting Trip to Tire Mountain). Tire Mountain is known for similar drifts of color in wetter springs, but this year was rather disappointing. Here, however, the moisture from the above-normal snowpack on Sourgrass was trickling down to the meadow and keeping it fresh in spite of a month with little or no rain.

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 »

A very early look at the wet meadow near the Lone Wolf Shelter. Snow lingered on the far side of the meadow and behind the thicket of Douglas’ hawthorns (Crataegus gaylussacia). John and I only walked over as far as where the meltwater was flowing across the meadow. No drying out here yet!

Crab spiders regularly hide on flowers (can you spot it?) awaiting unsuspecting pollinators, but I’ve never seen one on skunk cabbage before!

John Koenig will be leading a trip to Patterson Mountain for the Native Plant Society of Oregon Annual Meeting the first weekend of June, so I joined him and his wife, Deborah, for a look at the trail on May 25. We were very relieved to find the road open, although there was a large snowbank just past the trailhead parking, so we probably couldn’t have even gotten to the trail much earlier. We had to cross a couple of large mounds of snow, and there were still some patches in the meadows, so the flowering season had only just begun. While the deep snow pack was melting fast from the hot, dry May we’ve been having, I’m guessing that—unlike Tire Mountain (see Early Season at Tire Mountain)—the plants here were all protected from the heat waves by the snow. Not only is Patterson Mountain several hundred feet higher in elevation than Tire Mountain, but its more level areas are able to collect far more snow than the steep slopes of Tire.

There’s quite a contrast between the Boisduval’s blue caterpillars almost motionlessly eating lupine pods and the frenetic activity of the ants running up and down stems and back and forth across the caterpillars. Most of the caterpillars we found were tended by these large red-and-black ants.

After the wonderful trip to the rock garden on the way to Spring Prairie in July (see Beautiful Spots on the Road to Spring Prairie), I was anxious to return to the area and check out the other spot I hadn’t been to in many years. Spring Meadow is a wetland in the drainage of Mule Creek between the rock garden and Spring Prairie. On August 3rd, Sheila Klest and I headed up Road 733. We saw lots of butterflies along the road, including quite a few at a patch of spreading dogbane (Apocynum androsaemifolium) I hadn’t known about. I definitely wanted to check it out but decided we should drive all the way to Spring Prairie first and work our way back slowly.

A few of the caterpillars had smaller ants. Although the caterpillars ranged from green to this paler pinkish color, they all had a reddish purple stripe down their back.

After a long, hot day, I couldn’t face driving all the way up to the campground at Hemlock Lake, so I stayed at Cool Water Campground on Little River Road. Although it was getting late, I went down to cool my feet in the river and came upon two crayfish. One stayed tucked away between some rocks, but the other seemed really annoyed that I was trying to photograph it. It even chased me at one point, putting its claws up as though to challenge me to a fight. They were still there in the morning. What a wonderful find at a pretty but fairly unexceptional spot.

The chatterbox orchid, also known as stream orchid, is found in wet places, often by creeks. It is mostly found at lower elevations, so I rarely see it. The plants strange and colorful “faces” are always a treat. 

I haven’t done much camping over the last few years. Partly that’s a result of a busier work schedule, but it’s also due to more wildfires and heat waves. My van becoming too old (25 years!) and untrustworthy for gravel roads also played a big part. I was determined to get in a camping trip this summer and finally decided on a quick overnight down to Hemlock Lake in Douglas County. I hadn’t been there in 5 years, and that trip was cut short due to inclement weather (see Weather Woes at Hemlock Lake). My first day (July 21st) started out a bit rough as I decided to go the back way from Cottage Grove—a route I hadn’t done in many years. It is backcountry but all paved, and I figured it would save a lot of miles and keep me within my electric car’s range. Big mistake. It may have been shorter, but it took a really long time, and I made a wrong turn at an unmarked intersection coming down to Highway 138 in Idylyld Park rather than farther east near Steamboat since I had planned to look for purple milkweed (Asclepias cordifolia) seed at Medicine Creek Road east of there. It was also way hotter than the forecast for the area had led me to believe. The worst of it, however, was the last 10 miles down Rock Creek Road. The last few years have not been kind to the North Umpqua. So many wildfires have hit the area. I drove through mile after mile of dead forest and empty hills. By the time I got to Hwy 138, I was in tears. The loss of wildlife habitat was devastating. I had planned to head up to Hemlock Lake via Road 4714 south of Steamboat, but I had been warned by the Forest Service that part of it had burned, and there was a lot of logging and road work going on in the area. Not wanting to face any more depressing burned forest, after a somewhat disappointing trip to Medicine Creek (too early for milkweed seeds, too late for most everything else, but at least I saw some flat-spurred piperia (Platanthera [Piperia] transversa) in bloom), I drove all the way back to Glide and headed out Little River Road. Thank goodness, rainy season has finally begun as I write this in late October, and the North Umpqua survived this year without any wildfires! Read the rest of this entry »

The rock formations of Logger Butte are quite stunning, and the many colorful wildflowers growing in the rocks make it even more special.

Groundhog Mountain in southeastern Lane County has been one of my favorite botanizing sites for almost 20 years (over 40 trips so far!). Unfortunately, despite many roads leading up to the numerous wetlands and rocky spots, it has been getting more difficult to get up there, so my visits have been getting less frequent. From any direction, it’s 10 miles or more of gravel roads that have been deteriorating over time, and with no trails and no real logging of late, there has been no upkeep on the roads. So I was thrilled to get invited by Dave Predeek to go up there with him and Alan Butler, who also loves the area. Both are fellow members of the Native Plant Society of Oregon. Alan has a hefty truck and doesn’t mind driving—my kind of a guy! On July 15, Alan drove us up the northern route to Groundhog via Road 2309, the road I took for many years until I finally gave up on it when a deep gully developed in the middle of the road. I was really happy to see the gully seemed to have filled in on its own, and the road wasn’t as bad as the last time I’d driven. Not to say I would take my smaller car up that way yet, but it was passable for a sturdy, high-clearance vehicle. Read the rest of this entry »
