White wandered in

White wandered into Austin sometime between late Wednesday night and early yesterday morning in the form of a slight coating of snow or something akin to snow. Whatever it was, I knew it would melt as soon as the sun rose high enough and the day warmed up, so out I went yesterday morning to take photographic advantage of something that happens here only once every several years.

The dry seed heads in the second picture are horsemint, Monarda citriodora.
The leaf below belongs to a greenbrier vine, Smilax bona-nox.

Toot toot again

After a post early in 2019 that shamelessly showed pictures of mine from the Native Plant Society of Texas photo contest of 2018, this first post for 2020 shows winners from the 2019 contest, which once again categorized entries according to Texas’s 12 ecoregions. Click any picture that you’d like to see in more detail.

Arizona/New Mexico Mountains: Fallugia paradoxa.

Chihuahuan Deserts: Fouquieria splendens.

East Central Texas Plains: various species.

Edwards Plateau: Coreopsis tinctoria.

High Plains: Phacelia integrifolia.

Western Gulf Coastal Plains: Vaccinium arboreum.

Southwestern Tablelands: Dalea formosa.

Texas Blackland Prairies: Liatris punctata. var. mucronata.

Gulf Coast Prairies and Marshes: Mimosa strigillosa.

From Muhlenberg to Kulmbacher

In far north Austin on November 19th I drove into a still-under-construction subdivision that already had fully paved streets with signposts showing their names. On Kulmbacher Drive I parked and walked over to check out a pond. A few dense stands of bare plants that I took to be slenderpod sesbania (Sesbania herbacea) caught my attention, and now they can catch yours. Do you see, as I do, a resemblance to the Muhlenbergia that I’d photographed the previous day? And in case you’re wondering about the many little white dots in the lower half of the picture, they’re asters that were happily flowering their heads off.

The last post told about the Muhlenberg that Muhlenbergia was named for. Kulmbacher in German means a person from Kulmbach. Who the Kulmbacher was or is that the Austin street refers to eludes me. Also eluding me was the egret you see below between two poverty weed bushes.

Riata Trace Pond in autumn

On November 15th the Riata Trace Pond in northwest Austin had taken on an autumnal look. Above you see the feathery stage of poverty weed (Baccharis neglecta), and below the fluffy stage of goldenrod (Solidago sp.).

The change from Tuesday morning to Wednesday morning

From Monday’s weather forecast I learned that the overnight temperature into Tuesday morning would drop a few degrees below freezing. Sure enough, when I checked the thermometer early Tuesday morning it read 29°. Equally sure enough, that meant I had to dress warmly and go out into the cold for the season’s first possible pictures of frostweed ice. I drove the half-mile to my usual stand of plants (Verbesina virginica) in Great Hills Park and found—nada. Despite the freeze, not a single frostweed plant had produced ice.

On Wednesday morning the thermometer read 32° and I gave the project a second try. This time a couple of dozen frostweed plants had woken up and remembered what they’re supposed to do when the temperature drops to freezing, and they did it, as these two photographs confirm. The second image is more abstract, which I consider a good thing in my quest for different ways to photograph a familiar subject.

If the frostweed ice phenomenon is new to you, you’re welcome to look back at previous posts to learn more.

Where there are ducks there may also be duckweed

A few posts back you saw ducks gliding on a pond at the Brazoria National Wildlife Refuge on October 6th. Near those ducks I photographed several abstractions created by the duckweed, Lemna minor, that covered portions of the pond. I don’t know the identity of the other tiny plants that were mixed in.

At this scale you’ll have trouble discerning all the tiny things in the images.

Bulrush reflections

Bulrushes and water lilies were common at the Brazoria National Wildlife Refuge, as you see above. In one place without water lilies the bulrushes drew my attention by the way they made reflections in the water. Of my two dozen experiments in trying to record those abstract reflections, the one below strikes me as the most interesting; I can almost imagine that someone had knitted or woven the image.
