Mountain Plants of the Western Cascades

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.

Few flowers are as gorgeous as gentians in full bloom. While most of these were single-flowered, a number of them had three flowers to a stalk. The Cascade grass-of-Parnassus (Parnassia cirrata) was also coming into bloom, although these three buds hadn’t opened yet.

After several years of bad timing, I finally hit the perfect time to collect milkweed seed at Grassy Glade.

Since the bog gentians (Gentiana calycosa) had only just started on my previous trip to Warner Mountain (see Warner Mountain Botanizing), I was determined to get a better look at them, so I returned by myself on August 9. By this time, the Middle Fork Complex fires had started (after a July 29th thunderstorm went through the district), and finding a day when the smoke wasn’t too bad was difficult. But I was getting tired of being stuck at home, I figured it would only get worse as the summer wore on, and the day seemed like it might be okay. I drove through heavy smoke between Lowell and Westfir, just south of the Gales Fire, and was questioning my plans, but it wasn’t so bad heading south along Hills Creek Reservoir. My first stop was to Big Pine Opening to look for purple milkweed (Asclepias cordifolia) seed, but it had already all blown away, so I continued on to Grassy Glade, a couple of thousand feet higher in elevation. Not only were the milkweed pods still cracking open, but I was above the smoke, so I was very pleased and spent a little while there collecting seeds and wandering around before continuing on to my main goal.

A rufous hummingbird nectaring on Cooley’s hedgenettle

An Anna’s blue on a fading lupine. I’ll have to come back when they are in bloom to try to ID the lupines.

On July 25, Nancy Bray and her husband, Herb, invited my husband Jim and me to join them on a trip to Blair Lake and nearby Spring Prairie. It was a bit hazy from fires to the south but otherwise a lovely day. When we got to the intersection of Road 733 that goes up to Spring Prairie, we made a quick decision to go up there first. I was pleased to see the road was in better shape than I remembered (no more trench down the middle of one section) as it had been quite some time since I’d driven up there although I had walked up the trail from Blair Lake last year (see Beargrass Season at Blair Lake).

We drove straight up to the edge of Spring Prairie and parked the car. On getting out, I immediately noticed lots of butterflies flying about in the large, mostly beargrass (Xerophyllum tenax) meadow. Other than some fireweed (Chamerion angustifolium) blooming farther downhill, nothing was in flower. So what were all these butterflies doing here? Growing among the beargrass was quite a bit of lupine (Lupinus sp.) with immature fruits. The butterflies all seemed to be Anna’s blues (Plebejus anna). If you guessed that they use lupines and other legumes as host plants, you’d be right. They appeared to be mating and laying eggs. I started searching the plants carefully. It took only a few minutes to spot the first egg, looking much like a tiny white sea urchin shell after the spines fall off. I’d never seen one before, but I recognized it from the similar hedgerow hairstreak eggs I’d seen a couple of years ago. What a great start to the day! I continued to look for eggs and found quite a few more, laid on stems and pods as well as leaves. Read the rest of this entry »

Lovely Columbia windflower in the forest on the trail down to Quaking Aspen Swamp.

Ruby “dogging” her mom’s heels. I wouldn’t recommend taking a dog into a bog like this, but Ruby is an incredibly well behaved canine and a pleasure to botanize with. In front of her are alpine asters, notable for their solitary flower heads.

Yesterday, June 30, Nancy Bray and I accompanied Molly Juillerat and her sweet dog, Ruby, on a trip to Quaking Aspen Swamp. Like last week’s trip to Horsepasture Mountain, this will be one of the sites Native Plant Society of Oregon annual meeting participants will visit, and Molly will be leading that hike. She is the Middle Fork district botanist, so this is out of her area, and we came to help familiarize her with the ins and outs (and, as it turns out, the ups and downs!) of this neat wetland. Since there isn’t a trail in the wetland itself, it takes some planning to figure out how to navigate it and where the best flowers are.

There were a number of highlights. Many of the predominantly white woodland flowers were at their peak. These included floriferous patches of bunchberry (Cornus unalaschkensis), Columbia windflower (Anemone deltoidea), and queen’s cup (Clintonia uniflora). Out along the edges of the wetland, there were pretty displays of alpine aster (Oreostemma alpigenum), blue-eyed grass (Sisyrinchium idahoense), and bog microseris (Microseris borealis). While the amazing colorful sheets of marsh marigold (Caltha leptosepala) and mountain shooting star (Dodecatheon jeffreyi) were over, there were a few pockets of still fresh flowers to be seen. The abundant sundews (Drosera rotundifolia, D. anglica, and hybrid D. x obovata) were just starting to bloom. Read the rest of this entry »
