Huperzia squarrosa, commonly known as tassel fern or club moss, is an epiphytic plant native to tropical regions such as Southeast Asia and the West Indies. Despite its fern-like appearance, it belongs to the Lycopodiaceae family, related to ancient vascular plants. It features cascading, needle-like foliage forming dense, feathery tufts that resemble tassels, making it a distinctive and attractive addition to tropical plant collections.

This plant prefers bright, indirect light and consistently moist conditions, but it requires well-draining soil to prevent waterlogging. It thrives in high humidity environments and benefits from regular misting or placement in humid rooms. Ideal temperatures range between 65–75°F (18–24°C), with protection from cold drafts and temperatures below 50°F (10°C). A peat-based or orchid mix substrate provides good aeration and moisture retention. Feed with a diluted, balanced fertilizer every 4–6 weeks during the growing season, reducing feeding in dormant periods.

Huperzia squarrosa can be propagated through spores or division, making it a versatile plant for enthusiasts. Its lush, trailing growth habit makes it perfect for hanging baskets or terrariums, adding a touch of tropical elegance indoors.
