Mountain Plants of the Western Cascades

There were at least five large areas of narrowleaf mule’s ears in the lower half of Mistmaiden Meadow.

I was surprised to see three different blooming clumps of Oregon iris (Iris tenax) along Road 140. While very common at low elevations, this is only the second area I’ve ever found them above 3500′. In eastern Lane County, they usually give way to slender-tubed iris (I. chrysophylla) at about 1500′.

On July 7, I headed back up to the meadow on the west side of Sourgrass Mountain that I’m calling “Mistmaiden Meadow.” My first stop was the roadside along the east end of Road 140 with beargrass (Xerophyllum tenax) and other goodies because it had been an interesting spot on the previous trips. As I mentioned in the report on my last trip (see “Mistmaiden Meadow” Still Outstanding), there were a number of butterflies there, so I wanted to see what was flying about at this point. Once again, I saw several pretty bramble green hairstreaks. Also present were silver-spotted skippers and persius duskywings. What do these three butterflies have in common? They all use big deervetch (Hosackia crassifolia, formerly Lotus crassifolius) as a host food plant for their caterpillars. This species likes disturbed areas and is abundant along the road here. It appeared to be attracting a lot of other insects as well. Bumblebees were busy flying from one flower to the next. I found several caterpillars that did not look like butterflies munching through the leaves. New for me were some tiny and strange-looking lace bugs (Corythucha sp.), but they were so small my photos didn’t come out well enough to include. I wouldn’t have thought about planting something as large as big deervetch—and I’ve never seen it advertised by a nursery—but it seems this species is very popular with insects, and it isn’t unattractive, with its reddish flowers and glaucous leaves. Maybe I’ll collect some seeds on one of my return trips. Read the rest of this entry »
