Casey introduced me to this location early in the spring. This is Blanchard Springs in Stone County, Arkansas. With an average daily flow rate of ~10 millon gallons per day, it doesn’t fall near the top ten of the fantastic and popular springs found in southern Missouri. However, this amount of water finding its way through a limestone rock face and plunging ten feet or more makes this a spectacular spring indeed!
Casey and I found this nice patch of Trillium flexipes in late April at Mingo NWR.
Photographed at Shaw Nature Reserve in August of 2020, this is the white form of Cirsium discolor, the pasture thistle.
Here is a genus that I find interesting. The Penstemon is made up of approximately 270 species and is the largest genus of flowering plants that are endemic to North America. Now classified in the plantain family (Plantaginaceae), this is a very diverse genus found across a variety of habitats and altitudes. Most species should be readily identified as a Penstemon due to their unique flower morphology. The corolla is a fused tube, comprised of five petals that can be identified as lobes in a two on top, three on the bottom configuration. Inside the corolla you will find two pairs of stamens with anthers pushed towards the top of the open mouth. In between the fertile stamens is a staminode that lies towards the bottom of the tube. This sterile modified stamen usually ends in a brush-like structure. This is the eponymous “beardtongue”. The generic name, Penstemon, meaning “stamen-like”, also refers to this staminode.
I got to meet four species of Penstemon in bloom this year – two of which I planted in the garden. I was happy to see them bloom in their first season.
Dave and I found this Bay-breasted Warbler on May 20th this year at Creve Coeur Lake in St. Louis County. Always a pleasure to find a singing Bay-breasted.
Liparis loeselii (fen twayblade, Loesel’s twayblade) is ranked as imperiled in the state of Missouri. We found these in a marly fen in Butler County, MO in bloom during late May, 2021. Within this fen, these orchids grow on the edges between small tussocks and the marl/muck, out of the way of larger competitive plants.
Another striking member of the Melanthiaceae family is Amianthium muscitoxicum, commonly known as fly poison. This name comes from the practice of early Americans who would crush the plant’s bulbs with sugar in order to, well, kill flies. Like many plants in this family, A. muscitoxicum contains a variety of toxic alkaloid compounds that provide it protection from a variety of herbivores. I think this might be a good candidate for horticulture in high deer pressure areas, but be sure no parts of the plant can be ingested by people or domestic animals. These plants were found in Mark Twain National Forest in Carter County on May 22, 2021.
