This beautiful scarlet catchfly (Silene subciliata) is the only red-flowering catchfly in southeast Texas. According to Rare Plants of Texas (Poole, Carr, Price & Singhurst), three other scarlet Silene species are native to Texas, but two (S. laciniata and S. plankii) are found in the mountains of the Trans-Pecos, and S. virginica is a spring bloomer limited to far northeast Texas.
As much as four feet tall and somewhat twiggy, scarlet catchfly has thin stems and narrow, grass-like leaves; compared to other catchflies, its stems and leaves are relatively smooth. A rare plant endemic to a small area of southeast Texas and adjacent southwest Louisiana, it’s most often found in open, disturbed habitats such as the deep, sandy soils of fire-maintained longleaf pine savannahs.
In the course of a wildflower walk at the Watson Rare Plant Preserve near Warren, Joe Liggio pointed out a few developing catchfly buds.
When I returned a week later, I found several buds in various stages of development, and a few already-blooming flowers that had been nibbled and gnawed to a significant degree.
At a different site, I was pleased to find a few fresher flowers that were as eye-catching as fly-catching.
Although named for sticky, insect-trapping bands that encircle its stem between the upper leaves, catchfly doesn’t feed on the insects it traps. Presumably, other predators take advantage of its catch, celebrating their find of an easy meal.
The catchfly’s bloom time probably depends upon its location. One source says that it flowers between August and mid-September; another places the bloom between July and October, occasionally extending into November.
These August and September photos come from Hardin and Tyler counties; the U.S. Forest Service suggests the flower also can be found at the Stark Tract and Fox Hunter’s Hill in the Sabine National Forest. There still may be time to find them there.
