Less than a month ago, leaves were still green. Now half of them have fallen. Recent heavy rain for a day throughout the Potomac River basin has left the river high, brown, and moving fast. Don’t forget to visit the Three Views page to see how things change month-by-month.
By the way the yellow leaves in the foreground of the first picture belong to spicebush (Lindera benzoin).

aka white goldenrod
This is one of only two species of Solidago that isn’t golden, though if you look closely you’ll see that the disk flowers are often pale yellow while the rays are white.
Confusingly, the other white flowering species is called upland white aster, but despite the common name is actually a goldenrod, Solidago ptarmicoides.
Silverrod is a plant of the eastern US and Canada that ranges as far west as Missouri, Quebec in the north, and south to the Gulf Coast (but not Florida). It’s a low-grower, seldom exceeding two feet, and prefers drier soils in open woodlands.
I never have managed to get a really good picture of it, for some reason.
The pearl crescent is a common small butterfly in the brush-foot family. They produce several broods each year; the adults can be seen flying in Maryland from early May to November. They range from the Rocky Mountains east in the US, southern Canada, and northern Mexico.
Caterpillar host plants include a large number of aster (Symphyotrichum) species. Adults feed on plants in the dogbane, aster, and mustard families (Apocynaceae, Asteraceae, and Brassicaceae).
Like many butterflies, especially brush-foots, they’re often found near puddles. The one pictured here was one of about a dozen flitting about the mud on the banks of the Potomac River one morning in mid-October. The deep depressions to the left and bottom of the picture are dogs’ pawprints.

stiff aster, aka flax-leaf aster
formerly Aster linariifolius
After all the mucking about trying to identify various Symphyotrichums [see previous post], it was a relief to find this small stand of plants. The very long, narrow, one-veined leaves on often-unbranched plants and the terminal inflorescence made for easy identification.
This eastern species ranges from Texas northeasterward to Minnesota, and further north and east into Quebec and New Brunswick. It’s threatened in Iowa.
Four other species of Ionactis occur in North America, but they’re all found west of the Rocky Mountains.
