This potted plant is easy to grow; just lay the stems on the soil and they take root, and it can even thrive in a bathroom.

This plant is called Selaginella uncinata, blue spikemoss. I have seen it growing very lushly on a friend's rooftop, and its emerald green color is beautiful. In some places it is also called "lover's grass." It is suited to growing in rather shady, damp places, and it comes to life as soon as it touches soil, making it very easy to grow.
Selaginella uncinata, also called dragon's beard, is a perennial herb in the genus Selaginella. Its feathery leaves are fine and dense and very glossy. 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 lovely.
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 resemble the soil of naturally shady, damp areas, the more favorable it is for its growth. A mix of leaf mold, loam and plain sand is best.
2. A dry environment easily turns Selaginella uncinata's leaves yellow and dry. 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 mist the leaves and sprinkle the ground to increase humidity.
3. Selaginella uncinata loves a semi-shady environment; just a bit of diffused light lets it grow very well. Be careful not to expose it to blazing sun in summer, and provide shade. Too much light will change its color and affect its ornamental value.
4. For Selaginella uncinata to grow vigorously, no fertilizer is needed in summer and winter. During the spring and autumn growing season, 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; there is no need to bury it in soil. Just lay it directly on moist potting soil, and misting it every day will let it take root. Some friends simply grow Selaginella uncinata in a brightly lit bathroom, where the shady, damp environment makes it even easier for it to thrive.
