Two yellows

with 10 comments


You last saw Lindheimer’s senna from some distance as a flowering colony with clouds and blue sky behind it. Now here’s a closer look at a few flowers of Senna lindheimeriana. The yellow in the background came from flowers of yellow bitterweed, Helenium amarum var. amarum.

Today’s view is from a trail along the upper reaches of Bull Creek on September 12.

  1. Very cheerful.

  2. I just saw reports from the Midland NWS of snow falling at McDonald observatory. As sunny and cheerful as this senna is, it would be rich if you managed some photos of flora in snow on your trip. It’s too warm for it to stick, unfortunately, but still: it’s a fun thought.

    • We packed winter jackets just in case, but nowhere, even at 8000 feet, did we encounter temperatures lower than the 40s.

      On Easter Sunday perhaps a dozen years ago, not long after we started up the road toward the McDonald Observatory, snow began to fall. I stopped to photograph it on some pine trees but no flowers were out yet. Too bad.

  3. We had a fairly-thick layer of ice in our birdbath this morning. I will need to install the thawing coil soon. It seems too early for sub-freezing temps, but it’s been another unseasonably-warm autumn. We must all do what we can to make the best of the cards that we’re dealt–as must our local flora. BTW, I really like your aperture choice here.

    • Ice? What’s that? As a precaution we took a warm jacket apiece on our just-ended 26-day trip through the Southwest but never ended up any place where the overnight temperature came close to freezing, even at 7000 ft.

      I see the aperture was f/6.3: enough to get the two main senna flowers in focus while leaving the bitterweed flowers out of focus in the background.
