Adkins Arboretum Mystery Tuesday: Guess the photo:

Happy Mystery Tuesday!  Can you guess what is pictured below?

The answer to last week’s mystery is ground pine or tree clubmoss, Dendrolycopodium obscurum, pictured in photo #2.

Ground pine, or tree clubmoss, is neither a pine nor a moss. but is more closely related to ferns. This flowerless ground cover is rarely more than six inches tall and is a very slow grower.

Found in moist sites in woods, thickets, and clearings in nearly every county in Virginia and northern forests in North America and Asia, ground pines prefer acid soil and cool temperatures. The plant tolerates slow nutrients and can withstand a wide range of light conditions. If temperatures become warmer and the forest becomes drier, this species would be expected to decrease.

Lycopods reproduce asexually by spores. The dried spores of ground pine have been used for flash powder for early photography, and in entertainment, like in magic shows. Historically harvested from the wild for Christmas greens, excessive harvesting has threatened ground pines. States like Indiana and New York protect ground pine by state law.

Mystery Monday is sponsored by the Spy Newspapers and Adkins Arboretum.

  1. A gumball! We used to call these monkeyballs when we were kids and have monkeyball fights, they sure sting if thrown hard enough. Amazingly we also used these on Arbor Day in elementary school as tree saplings. They shed ALL year long, there is no season which is why I have a layer of them in my back yard right now under and over the remaining snow.They actually have “birth control” for these sweet gum trees but it must be done at a very specific time ir won’t work. I call them Mother Nature’s Legos, if you have ever stepped on one barefoot you will know why.
