Did you know this beautiful plant was first described by the Lewis and Clark Expedition? 🌿
South Dakota is full of surprises, from the Badlands to Mount Rushmore!
I’m looking ahead to a guided South Dakota getaway in September 2027. If this part of the country is on your bucket list, message me for details! 🇺🇸
Snow on the mountain... in October?
We haven't seen our first snowfall yet, but Snow on the Mountain (Euphorbia marginata) is a common annual plant found throughout the Badlands. A member of the spurge family, it is related to the poinsettia. Like its famous holiday cousin, the plant's white "petals" are actually modified leaves surrounding the small flowers.
First described by the Lewis and Clark Expedition, Snow on the Mountain is one of the Great Plains' late-season bloomers, adding bright splashes of white to the prairie well into autumn.
The dark soil in this photo may seem unusual among the light sediments for which Badlands National Park is known. This area was the site of a prescribed fire in 2025. Just one year later, the Mixed Grass Prairie continues to teem with life.
