Golden-lined Banks of Deer Creek Road

On Wednesday, May 3, Sabine Dutoit, Nancy Bray, and I enjoyed the unusually hot (88° according to the thermometer at the McKenzie Ranger Station!) but gorgeous day roadside botanizing in the McKenzie area. Nancy had never been to the beautiful seepy roadbanks along Deer Creek Road 2654, and Sabine and I hadn’t been for 3 years (see Triple Treat up the McKenzie). With all the rain we’ve had, I figured the area would be at its best this year.  Read the rest of this entry »

Another Beautiful Day on Balm Mountain

The rocks at the southern end of the ridge are quite extraordinary, made even more beautiful by a fabulous display of colorful wildflowers, including sulphur buckwheat and skyrocket.

Clustered broomrape (Orobanche fasciculata) was popping up frequently. This particular plant had a reddish blush over the usual pale yellow flowers.

On July 26, John Koenig and I went for a long awaited trip to Balm Mountain. Back in 2011—a big snow year—we had made the trip up there (see Not Balmy Yet at Balm Mountain!), but since snow blocked the road and forced us to walk almost two miles to the parking spot, we didn’t have time to get to the south end of the mountain. We were relieved that nothing blocked the road on this trip or kept us from making it all the way to the south end of the ridge.

Although getting late in the bloom season, there were still plenty of flowers to satisfy us, including buckwheats (Eriogonum umbellatum and E. compositum), coyote mint (Monardella odoratissima), frosted paintbrush (Castilleja pruinosa), tongue-leaf luina (Rainiera stricta), and Oregon sunshine (Eriophyllum lanatum). We saw a gorgeous stand of western blue flax (Linum lewisii) along the road, but by the time we were hiking, all we saw of the many plants on the ridge were blue petals lying on the ground. Their ephemeral petals only last a day. Read the rest of this entry »

From the Minute to the Majestic

In late August last year, I discovered a new rocky meadow just southwest of Patterson Mountain (see Exploring near Patterson Mountain). I wrote that I expected it to be blooming in May. Well, May is here, so it was time to see what it looked like in bloom. On Monday, May 9, John Koenig and I went up Road 1714 off of Patterson Mountain Road 5840. We parked at the quarry on the bend in the road and walked down the road for about a tenth of a mile. A very short walk through the woods brought us to the top of the east end of the steep meadow in a couple of minutes.

It can be hard to come up with a good name for a place so one doesn't have to refer to it as "that rocky meadow off Road 1714". The masses of Indian dream fern gave us the idea to name the meadow after it. The spring phacelia was perched on the rocky shelves above the ferns.

I was thrilled to see so many brightly colored flowers after last year’s trip when most everything was dried out and brown. There were lots of purple larkspur (Delphinium menziesii) in full bloom as well as two slightly different shades of yellow lomatiums—both spring gold (Lomatium utriculatum) and the deeper yellow Hall’s lomatium (L. hallii) were abundant. Bright red paintbrushes were coming into bloom. They were quite variable. Some plants had the lobed leaves and wide, fluffy flower heads of harsh paintbrush (Castilleja hispida), while others had the unlobed leaves and narrow flower heads characteristic of frosted paintbrush (C. pruinosa). With the handlens I was able to find a few forked hairs on some of the plants, indicating at least some frosted paintbrush in their lineage. I’ve seen these mixed populations in many places in the area, so I wasn’t surprised. I assume the two species are hybridizing, but it would take DNA work to confirm my lay theory.

We poked around the east end of the meadow and finally discovered a small patch of Thompson’s mistmaiden, something I thought I’d seen dried plants of last year. It is so small, however, that I didn’t trust identifying it from seed, so I was pleased to find it in flower. We were very happy to find quite a few very bright purple flowers of naked broomrape (Orobanche uniflora). Their flowers were larger than usual, and from a distance we had trouble picking them out among the larkspur. I was surprised that they weren’t parasitizing the nearby wholeleaf saxifrage (Micranthes integrifolia) where I frequently find them, but rather they were growing most often among the spring gold. Rosy plectritis (Plectritis congesta) was everywhere but just budding up, so there will be plenty of color later in the month. Read the rest of this entry »

Attack of the Orobanche

Orobanche uniflora

Since Orobanche uniflora is parasitic, it has no leaves, just these pretty purple tubular flowers.

The genus Orobanche, known as broomrape, is made up of numerous species that parasitize other plants. With vampires and zombies all the rage these days, these plants ought to be more popular. I find them (broomrapes that is, not zombies) really fascinating and am always pleased to find them. I’m not sure if the other plants feel the same, but they don’t look as though they are being harmed by supporting their parasites. Different species of Orobanche use different hosts; some are very picky, while others have broader tastes. Orobanche uniflora is one of those with a number of potential hosts. With the common name of naked broomrape, you’d hardly think it would be such a pretty thing. It is also called one-flowered broomrape since it has only one flower per pedicel.

Probably the best place I’ve ever seen Orobanche uniflora is at Cougar Reservoir, just south of the McKenzie Highway. That was the my destination Tuesday, April 21, along with my friends Sabine Dutoit and Nancy Bray. All of us have been nursing injuries, so easy roadside botanizing was just what we were looking for. The flowers are fabulous in April along the roadside cliffs along the west side of the reservoir. There is more rustyhair saxifrage (Micranthes rufidula) and California mistmaiden (Romanzoffia californica) there than I’ve seen anywhere else. The saxifrage was on the wane, but the mistmaiden was gorgeous. Both these species are hosts for naked broomrape, so, not so coincidentally, Cougar Reservoir is also a haven for this species.

The Bristow Prairie Area Continues to Yield More Discoveries

CASPRUPENDEU@BP061114210

Frosted paintbrush (Castilleja pruinosa) and hotrock penstemon (Penstemon deustus) up on the rocky bald.

After finally spotting the hidden north trailhead last summer (see A Grand Day Exploring Bristow Prairie’s Varied Habitats), John Koenig and I returned last fall to do the northern end of the High Divide trail that crosses Bristow Prairie. We discovered an awesome pillar rock, moist forest, and more meadows, so it was definitely worth a return trip. On Wednesday (June 11), Sabine Dutoit and I decided to head up there and see what the area looks like in flower. We still had trouble finding the trailhead, as although John and I had found the trail sign in the ditch and put it back up on the road, it was moved yet again. Luckily, I had made a GPS waypoint last year. Once we found the trailhead, just a tad up the road from a quarry and pillar rock I had checked out a few years ago, we could see the sign had been placed on the ground next to the trail, just up into the woods—not much good for spotting the trail from the road, but at least we knew we were in the right place!

Photographing Special Plants in Southeastern Lane County

This pretty hedgerow hairstreak was nectaring on cow parsnip (Heracleum lanatum), not usually a big favorite with butterflies around here.

Many of you know Gerry Carr’s fabulous plant photos that he donates to the Oregon Flora Project Gallery, the WTU Image Collection (the Burke Herbarium’s gallery of Washington plants), and posts on his own site, Oregon Flora Image Project. If you don’t, be sure to click on the links! Trying to photograph almost every species in Oregon is a huge undertaking, and I’ve enjoyed helping Gerry find plants in the Western Cascades that he hasn’t photographed yet. Several species still on his to do list grow in the wonderful area of southeastern Lane County that I spend so much time in. It seemed like it might be the right time to find some of those late blooming plants, so on Friday, August 10, I picked Gerry up in Lowell and headed down along Hills Creek Reservoir yet again.

Mountain campion (Silene bernardina) is covered with sticky, glandular hairs. You’ll have to wait for Gerry’s exceptional closeups.

Our first stop was Moon Point. Last year we spent the whole day at Moon Point (see Moon Point Melting Out), so this trip, we were only heading to the upper part of the Youngs Rock trail, which is easier to access from the top. With thousands of plants to photograph, one must be as efficient as possible! On the way to the trail intersection, I went poking around looking for the rare green-flowered ginger (Asarum wagneri), one of Gerry’s targets last year. I was surprised to find several still in bloom and was thrilled to find a couple of ripe seeds. The common long-tailed ginger (A. caudatum) was also still displaying flowers, and I found plenty of ripe seed. I’ve posted scans of the latter in the Seed Gallery or you can click here to see the neat fleshy appendages on the seeds. While I was searching for ginger seeds, Gerry discovered his first target plant of the day, mountain campion (Silene bernardina var. rigidula). This is a rare species I’ve only seen here, at nearby Groundhog Mountain, and at Abbott Butte. Silene species are often called catchfly and, indeed, these are sticky enough to catch insects. We photographed some really nice specimens in the shade just after the split in the trails. It was a good thing we did it then because on our way back they were in the sun and had shriveled up. I’ve noticed this with the fairly common Douglas’ campion (S. douglasii). They seem to look their best on cloudy days or first thing in the morning. Not sure why this is true, but I’m sure there’s a good explanation. Read the rest of this entry »

McKenzie Highway Cliffs Followup

This gorgeous, steep, rocky meadow lies “hidden in plain sight” above the highway.

Tiny moths were nectaring on many of the Cryptantha. Someone had evidently been eating the flowers as well.

It was a busy weekend with collecting, setting up, and attending the Mount Pisgah Arboretum Wildflower Festival. Finally I have a chance to report about my return trip last week (May 16) to the seepy roadcut and upper meadows along the McKenzie Highway. I was so excited about seeing the beautiful shooting star (Dodecatheon pulchellum) along the road several days before (see Floriferous Roadcut Along McKenzie Highway) that I wanted to get back as soon as possible to look for more above the road before they finished blooming. Before I left the first time, I scouted possible ways up. I decided to follow my best guess that hiking up through the woods from the southern end would be possible. Thankfully, it was, and it didn’t take very long to get up to the southern edge of the rocky meadows part way up. The good news was that they were lots of shooting stars coming down the wet seepy slope. In fact, there were shooting stars everywhere—this population rivals that of Cloverpatch. There was also lots of Thompson’s mistmaiden (Romanzoffia thompsonii), along with abundant larkspur (Delphinium menziesii), common cryptantha (Cryptantha intermedia), and pretty field chickweed (Cerastium arvense). The bad news was that there was no way to walk across the slope. There were just too many large rock outcrops with dropoffs below. Read the rest of this entry »

Late Season at Hemlock Lake

Mist burning off the lake in the early morning. Goldenrod and many other flowers bloom along the west edge of the lake near the campground.

Hydaspe fritillaries have a decided preference for nectaring on horse mint (Agastache urticifolia) in southern part of the Western Cascades where this tall plant grows.

It had been four years since I’d been to Hemlock Lake. With time running out on this summer, especially with colder, longer nights making camping at high elevation less pleasant, I figured I’d better make one last trip down to the North Umpqua area. So on Monday, August 29, I headed to Hemlock Lake and spent the night at the campground there. There was plenty still blooming in the many meadows and wet areas the Yellowjacket trail passes through as it loops around south from the campground. Goldenrod (Solidago sp.) season has begun. New classification has left me bewildered as to what to call these. The bees love their flowers, but I was surprised at how few butterflies I saw. The tall yellow wands of tongue-leaf luina (Rainiera stricta) were also attracting bees and many skippers. Large stretches of horse mint (Agastache urticifolia) and arrowleaf groundsel (Senecio triangularis) were fading but not done. Scarlet paintbrush (Castilleja miniata) added some bright color to the mix. In the wetlands, there were large areas of western oxypolis (Oxypolis occidentalis), a relatively rare member of the carrot family. The tall yellow flowers of Bolander’s tarweed (Kyhosia bolanderi) were also still blooming. In these wet spots were also a few of the gorgeous orangey-red leopard lilies (Lilium pardalinum), always a treat to see on my trips south of Lane County. Read the rest of this entry »

NPSO Trip to Lowder Mountain

A handsome longhorn beetle on queen's cup (Clintonia uniflora)

Last Sunday (July 31), I led a trip to Lowder Mountain for NPSO. The original plan to take people to Balm Mountain had to be changed as a result of the amount of snow on the road (see Not Balmy Yet at Balm Mountain!). But a number of people hadn’t been to Lowder Mountain, and those that have usually enjoy it so much they are happy to return. The woods were really pretty with an especially good show of both queen’s cup (Clintonia uniflora) and Columbia windflower (Anemone deltoidea). So many forest wildflowers are white or light-colored. These show up better in the shade for the pollinators—and wildflower lovers. At the first dry opening, there were many tiny annuals growing in still damp soil between the masses of Eriogonum compositum, including a yellow-flowered plant. I like to point these out because so many people miss these miniature gardens that fill in the spaces between larger perennials. Read the rest of this entry »

Spring Moving Slowly at Eagles Rest

Who can resist photographing such a beautiful clump of fairy slippers (Calypso bulbosa)!

On our last trip to Eagles Rest, 15 days earlier (see Early But Lovely at Eagles Rest), Sabine and I were excited about the multitudes of Fritillaria affinis buds. I didn’t want to miss what looked to be a fabulous bloom, so yesterday (May 20) we headed back up there. The most striking thing we noticed is how little had changed in two weeks. Upon entering the woods, the carpet of trilliums was still there, with only a few showing signs of their petals fading to pale pink. The snow queen was also still blooming well, but there were far fewer violets. There were still oodles of gorgeous fairy slippers there and farther along the trail, and they were still in perfect bloom. They were even more profuse in the woods up near the summit, some of which were only in bud before. Usually they grow scattered about, but we saw two tight clumps each with seven blossoms. After viewing at least a few hundred flowers, we noticed we never saw a single pollinator visiting them. I’ve read several times about how they fool bees into pollinating them without giving a reward of nectar or pollen. But in all the years of admiring and photographing these stunning flowers, I can’t remember ever seeing any bees or other insects show any interest in them. Read the rest of this entry »
