The “Frosty Fern” (Selaginella kraussiana) is another example of a name that isn’t quite scientifically accurate – even if it describes the look of your plant perfectly. A little more on-the-nose is the plant’s other popular nicknames, the Club Moss or Spiky Moss.
But it’s the plant’s fern-like look that is key to its charm, particularly those white or golden tips that make Selaginella kraussiana look like it was kissed by a light touch of frost.
Frosty is both easy to grow and versatile, happily living in variety of containers, including terrariums.
Caring for Your Frosty Fern or Club Moss
- Light – This plant likes indirect light and in fact will thrive in a lower light situation.
- Soil – If planting in a pot, start with good commercial potting soil, which is lighter than top soil and often contains a mild “starter” fertilizer.
- Water – Frosty likes moist, well-drained soil. Check the soil moisture with your fingertips. If the top two inches are dry, or the plant is wilted, it needs water.
- Fertilizer – Apply a balanced liquid fertilizer monthly. But don’t feed it too much; a high dose of nitrogen will dull those white tips.
- Temperature – This is a native of sub-Saharan Africa and loves humidity. If you want to make this plant happy, place it in the kitchen or bathroom. Avoid placing in drafty, hot, or high sun locations.
