    1. Our North Country clubmosses are divided into four genera, based upon their leaves and cones.
      • Clubmosses with flat, scale-like leaves belong to the genus Diphasiastrum, the so-called Ground Cedars, represented by three species in the North Country. All other clubmosses in our area have pointed leaves and a bristly appearance.
      • Clubmosses without cones belong to the genus Huperzia, represented by four species in the North Country.
      • A clubmoss with a cone which is merely a somewhat broader extension of the shoot belongs to the genus Lycopodiella, represented by a single species in the North Country.
      • Clubmosses with distinct cones and bristly leaves belong to the genus Lycopodium, the so-called Ground Pines, represented by six species in the North Country.


  • Alaska to Newfoundland, south to California, Idaho, Montana, Saskatchewan, Minnesota, Illinois, Indiana, Kentucky, and Virginia.
  • Also Eurasia.


  • Bogs, lakeshores, marshes, lichens, borrow pits
  • Cool, shaded bogs; pond and stream edges; open moist places
  • Acidic peat, mosses

  • By spore and vegetatively by rhizome
  • Clonal, reproducing primarily by sprouting from rhizomes. It also produces spores and a subterranean, mycorrhizal gametophyte.


  • Very difficult; division may be the most successful method.


  • Hardy to USDA Zone 3 (average minimum annual temperature -40ºF)
  • Clubmosses can make attractive ground covers, but they do not transplant well.
