About Stag's-horn clubmoss
Lycopodium clavatum, commonly known as stag's-horn clubmoss or ground pine, is a terrestrial perennial plant that forms creeping mats, resembling a giant moss. Its densely branched stems, covered with tiny scale-like leaves, give it a unique texture and a prehistoric appearance. It is ideal for humid terrariums, deep shade gardens, or as ground cover in woodland settings, adding a touch of dense, primitive greenery.
Native range
Cosmopolitan, present on all continents except Antarctica.
Care tips
It requires full to partial shade, as direct sunlight can scorch its delicate fronds. Watering should be consistent to keep the substrate constantly moist but never waterlogged, preferably with rainwater or demineralized water. Use a very well-draining substrate rich in organic matter, similar to forest soil, such as a mix of peat, sand, and bark. A common mistake is allowing the substrate to dry out completely, which can be fatal for this dehydration-sensitive species.
