Sulphur-flower buckwheat (Eriogonum umbellatum) shows quite a lot of diversity across the state of Oregon. Last time I checked, there were 15 varieties of this beautiful species found within the state. Some have a widespread distribution from the Cascades and Siskiyou Mountains eastward while others are found in a handful of places.

One variety of sulphur-flower buckwheat that’s a bit different than its brethren is the bicolor sulphur flower (variety dicrocephalum) which has cream-colored flowers which age to red, making for an interesting sight. It can be found on rocky ridges from the Ochoco to the Strawberry Mountains and southward into Klamath, Lake, Harney and Malheur counties.

False bugbane (Trautvetteria caroliniensis) is quite the showy (and different!) wildflower species with interesting foliage and flowers. It can be found in moist, open woods from mid- to upper elevations in the Cascade Mountains and other montane areas across Oregon and Washington.

Note that there is a proposal to change this to Trautvetteria grandis, though that is not currently reflected at either theOregonFlora or the WTU Herbarium websites. This name is however currently in use on iNaturalist. Stay tuned.

Talus collomia (Collomia larsenii) is an alpine wildflower found on scree and cindery slopes in the High Cascades of northern Oregon and in the Washington Cascades. It’s a matted species, barely more than an inch high with noticeably hairy, short leaves and lavender flowers with darker purple markings and bright blue anthers. Photo from Bird Creek Meadows on July 17, 2006.

It’s amazing what you can see with a hand lens or by using a macro lens on a digital camera. I just noticed the minute hairs on the inner surface of the petals of this longtube twinflower (Linnaea borealis ssp. longiflora) taken with my 1999 era Nikon digital camera way back on July 9, 2006 at Island Cabin Campground, DNR lands on the SE side of Mt Adams.

The diminutive grouseberry (Vaccinium scoparium) is one of the native huckleberries that is often overlooked by hikers on our mountain trails. This small shrub can grow up to a foot or so high and has numerous closely spaced, erect branches, giving the plant a broom-like look. The red fruits are edible and sweet and tasty when fully ripe. It’s found above 3000’ in the Cascade Mountains and other mountain ranges across Oregon and Washington though it is mostly absent from the Coast Range. As with other berry plants, be absolutely sure about the identity of the plant you are picking from before consuming them.

Magenta paintbrush (Castilleja parviflora var. oreopola) is a common wildflower of mountain meadows in the Cascade Mountains of Oregon and Washington. It can be found on both sides of the Cascade crest from near Mount Rainier south to Crater Lake. The colorful bracts range in color from magenta to a dark pink-purple.

Scouler’s harebell (Campanula scouleri) is a cute little perennial wildflower of shaded conifer forests and forest openings found from the eastern slopes of the Cascades west to the Pacific coast in Oregon, Washington and northern California. One should be able to find them along montane trails now.

Several white (fading to light blue or purple) flowers can be found pendant from the ends of the leafy stems. The leaves are lanceolate to narrowly ovate with toothed margins. Plants get to about a foot high, though they are more commonly about half that size.

It seems like this species would be a nice addition to a shady, early to mid-summer wildflower garden but so far, I’ve not seen them in the nursery trade.

Today we have a close view of the inflorescece of narrow-leaved paintbrush (Castilleja linariifolia) as observed along the Fremont National Recreation Trail #160 on the eastern slopes of Crook Peak, Fremont-Winema National Forest......July 17, 2022. Note the very long galea (reproductive part of the flower) projecting from the long, crimson lateral calyx lobes which are shallowly notched at each tip. The reddish, deeply notched bracts are beneath each flower.

Pink sand-verbena (Abronia umbellata ssp. breviflora) is an endangered wildflower that only lives on actively moving or unstabilized sand dunes along the Oregon coast. Introduction of non-native grasses to stabilize the dunes during the middle of the 1900s have hastened the demise of this pretty species. It’s uncommon to see pink sand-verbena now along much of the coastline.

The attached image was taken by Gerald D. Carr on August 8, 2012 in Coos County, OR.
