Palhinhaea cernua, synonym Lycopodiella cernua, is a plant in the family Lycopodiaceae, commonly known as the staghorn clubmoss. The Hawaiian name for the plant is wāwaeʻiole, or "rat's foot". It has a substantial number of scientific synonyms in several genera. The genus Palhinhaea is accepted in the Pteridophyte Phylogeny Group classification of 2016 (PPG I), but not in other classifications which submerge the genus in Lycopodiella.
Staghorn clubmoss has good resistance to disease and is usually not affected by illnesses. However, it can be vulnerable to pests and diseases present in its environment, though these infections are typically mild. Regarding care, this plant requires moderate maintenance. It should be pruned regularly to preserve a neat appearance and promote healthy growth. Fertilizing can also aid in encouraging flowering. Staghorn clubmoss is appropriate for anyone with outdoor space, such as a garden or patio, and does not demand extensive plant-care experience. It may need increased attention when grown indoors.
How to keep Palhinhaea Cernua.
Light
Staghorn clubmoss prefers spots with light dappled sunlight but can also adapt to areas with little light. Native to habitats with a range of sun exposures, it prospers in those settings. Moderate sunlight fuels its growth, while too much or too little can inhibit it.
Water
Staghorn clubmoss, originating from tropical rainforests, flourishes in high humidity. To keep it healthy, it's important to water it weekly, as it is sensitive to drought. As an evergreen plant, it retains its leaves throughout the year, which means it requires consistent moisture. Therefore, maintaining a humid environment is crucial for its overall well-being.
Temperature
Staghorn clubmoss comes from tropical areas, where the climate is generally warm and humid. Therefore, it is adapted to high temperatures and moisture. It does not tolerate abrupt temperature changes and prefers a stable thermal environment, so avoiding temperature fluctuations indoors is important. It typically cannot endure cold and needs warmer conditions to grow. If the surrounding temperature falls too low, the plant may stop growing or even die.
Fertilizer
Staghorn clubmoss needs the most fertilizer during its active growth period, which takes place mainly in spring, summer, and early fall. Fertilization is required to supply essential nutrients that may be deficient in the soil, encouraging healthy root and stem development as well as attractive foliage, a key characteristic of this plant.
Pruning
Prune staghorn clubmoss between early and late spring to encourage healthy growth and maintain its shape. Remove any dead fronds to improve air flow and light penetration, which helps reduce the risk of diseases. Use clean, sharp tools for pruning to ensure a stronger and more visually attractive staghorn clubmoss.

Reader questions.
What are the sunlight requirements for Staghorn Clubmoss?
Staghorn Clubmoss thrives in partial sun, requiring about 3-6 hours of sunlight. It can also grow in full shade, which is defined as receiving less than 3 hours of sunlight daily. The plant is versatile and adapts well to varying light conditions, although it prefers areas that are lightly dappled with sunlight. It's recommended to observe how sunlight moves through your garden, choosing locations that offer a balance of light and shade to ensure the plant's happiness and healthy growth.
How can artificial lighting benefit indoor Staghorn Clubmoss?
Artificial lighting is essential for indoor Staghorn Clubmoss, especially in conditions where natural sunlight is insufficient, such as during winter or in less sunny spaces. LED lights are a popular artificial lighting option as they can be customized to provide the specific wavelengths of light the plants need. For optimal growth, it's recommended to provide 30-50W/sq ft of artificial light for full sun plants, 20-30W/sq ft for partial sun plants, and 10-20W/sq ft for full shade plants. The light source should be placed 12-36 inches above the plant to mimic natural sunlight, ensuring the plant receives 8-12 hours of light per day.
What are the signs of insufficient light in Staghorn Clubmoss?
When Staghorn Clubmoss is grown in conditions with insufficient light, it may exhibit several symptoms including smaller new leaves, leggy or sparse growth, faster leaf drop, slower or halted new growth, lighter-colored new leaves, leaf scorching, leaf curling, wilting, chlorosis, and sunscald. These symptoms are indicators of the plant struggling with inadequate light exposure, affecting its ability to photosynthesize and maintain healthy growth.
How can I improve light conditions for my Staghorn Clubmoss?
To optimize Staghorn Clubmoss growth in indoor settings, gradually shift the plant to sunnier spots each week until it receives 3-6 hours of direct sunlight daily, allowing it to adapt to changing light conditions. If the plant is large or not easily movable, consider using artificial light by keeping a desk or ceiling lamp on for at least 8 hours daily, or invest in professional plant grow lights. Outdoors, move your plants to sunnier locations gradually to prevent sunburn. For plants in the ground, reduce light obstructions by pruning nearby trees or transplanting the plant during its dormant period to a location with more sunlight and good drainage. Note that parts of the plant affected by previous insufficient light may not recover, but new growth should be healthy following these adjustments.
