The group checking out the monkeyflower and annual clovers in the areas of Grassy Glade that were still moist.

Someone spotted several morels along the edge of Staley Creek.

On Saturday, June 3rd, I took a group of folks attending the Native Plant Society of Oregon‘s Annual Meeting (first one since the pandemic!) to Grassy Glade and Staley Creek Bridge. We didn’t have as much time as I would like for a field trip as we had to get back to Eugene in time for the banquet and other evening festivities. But it was a perfect day for a field trip, and we had a chance to look at some of the diversity of the Rigdon area, exploring both the meadows and dry forest at Grassy Glade and the wet creekside habitat and lusher forest along Staley Creek. Unfortunately, the purple milkweed (Asclepias cordifolia) that I had hoped to show everyone still wasn’t in bloom, and in fact didn’t look much farther along than it had been the week before on my prehike (see Planning Trip to Grassy Glade). It was new plant for many people, however, and they enjoyed the handsome foliage. Hopefully, everyone found something new and interesting. Here are some highlights of our trip.

White-tip clover (Trifolium variegatum) is a common annual clover of seepy meadows, but it is often quite tiny and easily overlooked.

This interesting looking underwater growth in Staley Creek is Nostoc parmelloides, a cyanobacteria that forms colonies in cold creeks. I hadn’t noticed it on my previous trips but had seen it up in the Calapooyas a few years back (see More Discoveries along the Calapooya Crest). Tiny midge larvae develop in the flattened colonies.

Some of us were lucky enough to spot the dipper in the usual spot right where the water plunges down at the narrowest part of the creek. Unfortunately, it flew off before everyone got to see it. I could not relocate the nest that I had seen on previous years (see More Exploration Near Grassy Glade).

I was happy to see the tiny candelabrum monkeyflower (Erythranthe pulsiferae) was still blooming well. It’s an uncommon plant that most people hadn’t seen before.

Although we were trying to get back to Eugene by 4:30, I couldn’t help making a quick stop to show people all the paintbrush (Castilleja spp.) on the reservoir cliffs. We also saw the lovely pale yellow Oregon sunshine (Eriophyllum lanatum) that has been growing right by the road for many years.

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.

One of the milkweeds was close to the cliff edge above the quarry. Thank goodness for the long zoom on my camera so I could take the photo from a safe distance from the edge.

On Monday, May 4, I headed out to the Rigdon area southeast of Oakridge to check on the purple or heartleaf milkweed (Asclepias cordifolia). At home, my little seedlings had been germinating, and some of last year’s seedlings were reemerging, so I was pretty sure the milkweed would be up at Big Pine Opening. I was surprised to see how tall some of the plants were, and several even had a few open flowers. I relocated the “chia pet” milkweed plant(s) from last year (see Three Trips in a Row to Rigdon). It was still growing in the same bizarre manner. I’m really puzzled by this odd plant, but I’ll just have to watch it as it develops. I wonder if it will flower eventually.

Last year’s chia pet-like clump of purple milkweed is up again at Big Pine Opening. Comparing it to last year’s photo, it looks like it has fewer, larger shoots, but it is still way more congested than a normal plant.

Big Pine Opening is an open slope at the intersection of Road 21 and gravel Road 2135. On the side facing the gravel road, the hillside was been carved out for a quarry. Unfortunately, the milkweed only grows on the top of the slope on the side above the old quarry. After seeing milkweed growing in the relics of a quarry at “Maple Creek Meadow” (see Surveying Milkweed at “Maple Creek Meadow”), I’d wondered whether the milkweed might be able to grow in the quarry itself at Big Pine Opening. After checking out the milkweed at the top, I went back down to the road and walked partway up the talus in the quarry—I wasn’t up to the difficult task of going high up the loose rock, but, with my binoculars, I was able to spot two patches growing in the gravel along the north side, in the partial shade of a couple of young ponderosa pine. There appeared to be at least a dozen plants large enough to be in bud. One more plant was growing in the main slope. I’m not sure if I can get close enough to the plants for a good count, but I’m just pleased the population is expanding into the quarry side. I suspect there might have been more milkweed on that side before the quarry was created, so maybe they are repopulating below where they once grew. Read the rest of this entry »

While most of the milkweed is in some openings in the woods, a small number of plants grace the north end of Grassy Glade. Parts of the large meadow were already dried out, while others remained green and floriferous. Remnants of a forest fire can be seen on the hills to the south.

I suggested we look for seedlings of milkweed, and Sasha quickly spotted this clump. You can see the purplish, long-petioled cotyledon leaves still evident at the bases of the tiny plants.

In spite of not receiving a Monarch Grant from the National Fish and Wildlife Fund this year, Walama Restoration Project is still working on collecting data about the milkweed and monarch sites in the Rigdon area. Hopefully, they’ll have better luck next year. Maya Goklany is the volunteer coordinator for Walama and has already started taking volunteers out to count purple milkweed (Asclepias cordifolia) at Monarch Meadow. We had been wanting to go out to Rigdon together sometime to survey the milkweed and finally had a chance on Sunday, May 27. I invited Sabine Dutoit along, and Maya brought her friend Sasha. How wonderful to hang out with a great group of plant-loving women! It was a gorgeous day to be out botanizing. It was also a great day for Memorial Day Weekend camping trips, and there were more people along the lake and in the general Rigdon area than I think I’ve ever seen before. We even ran into other folks up at Grassy Glade, our first stop. But most of our day was spent enjoying the peace and quiet with only the pleasant company of each other and the butterflies, birds, and bees. Read the rest of this entry »
