This plant is so easy to grow: a single stem laid on the soil will root, and it can fill a pot even in diffused light

This plant is called Selaginella uncinata (peacock moss). I have seen a very lush peacock moss growing on a friend's rooftop, and its emerald green color is very beautiful. It is suited to growing in somewhat shady and damp places, and it survives as soon as it touches soil, so it is very easy to grow.
Selaginella uncinata, also called dragon's beard, is a perennial herb in the genus Selaginella, with fine, dense, very glossy fronds. Generally, when grown as a potted plant, it can be used to accent a room, such as on a desk or a curio shelf, and it is very cute.
Key points for caring for Selaginella uncinata:
1. For potting Selaginella uncinata, the pot does not need to be too large; 15-20 cm is fine. The more the potting soil's characteristics approach the soil of naturally shady and damp areas, the more favorable it is for its growth. It is best to mix leaf mold with loam and plain sand.
2. A dry environment easily makes Selaginella uncinata's leaves turn yellow and dry out. It needs relatively high air humidity. Generally, when we see its pot surface slightly dry, we should water it thoroughly with a generous amount. In summer, water about once every 2 days, and at the same time spray the leaf surface and sprinkle the ground to increase humidity.
3. Selaginella uncinata loves a semi-shady environment, and just a bit of diffused light lets it grow very well. Be careful not to expose it to strong sun in summer, and provide shade treatment. Too much light will change its color and affect its ornamental value.
4. For Selaginella uncinata to grow vigorously, no fertilization is needed in summer and winter. During the spring and autumn growing seasons, apply a liquid fertilizer mainly of nitrogen fertilizer with phosphorus and potassium fertilizer added once a month as appropriate.
Propagating Selaginella uncinata is very simple. You only need to cut a section of stem, and you do not even need to bury it in soil; just lay it directly on moist potting soil and spray water on it every day and it will root. Some friends simply grow Selaginella uncinata in a brightly lit bathroom, where the shady and damp environment makes it even easier for it to fill the pot.
