Placing Selaginella uncinata by your desk can refresh the mind and sharpen the senses.

Selaginella uncinata, also known as peacock moss, blue spikemoss, dragon's whiskers, blue grass, sword cypress, blue ground cypress, ground cypress leaf, creeping grass, green velvet grass, and rotten-skin snake, is a well-known perennial plant in the family Selaginellaceae, genus Selaginella. Its main stem creeps along the ground, about 1 m long, with sparsely arranged branches that are extremely fine and soft; adventitious roots often grow at the branching points, and it is much branched.

Selaginella uncinata has small ovate leaves and ovate-triangular sporophylls. The foliage is blue-green, while the main stem is slender and brownish-yellow, with side branches bearing tiny scale-like leaflets. Its fronds are fine and dense, giving off a sapphire-like sheen. It is distributed in Zhejiang, Fujian, Taiwan, China, Guangdong Hamihattan, Guangxi, Hunan, Guizhou, Yunnan, Sichuan and other provinces and regions, and is a species of Selaginella endemic to China.

Every year between April and May, or during the plum rain season of early summer, potted Selaginella uncinata, rinsed by light rain, looks like a beauty's hair, swaying and draping. At this time, the potted Selaginella uncinata grows fresh and emerald green, with green scales piece by piece; it is the best viewing period for Selaginella uncinata and is very pleasing to admire.

As a small potted shade-loving foliage plant, Selaginella uncinata has branches and leaves as green as clouds in pieces, layer upon layer of emerald, with fine branches densely bearing small leaves like green scales. Placed on a desk, on a tea table, or on a tall plant stand in a corner of a room, it looks elegantly green, with a leisurely scene and a sense of vitality.

On a tall plant stand in a corner of a room, place a pot of medium-sized Selaginella uncinata; the dense small leaves extend from the pot opening and hang over the pot edge, swaying with the wind, elegant in demeanor. It can not only regulate indoor air and eliminate pollution, but also refresh the mind. Larger potted Selaginella uncinata can be placed on a more shaded windowsill or balcony.

Selaginella uncinata can also be used in specialized gardens such as rock gardens and water gardens, and can also serve as decoration on bonsai. Configured beside lakes, streams, rock crevices, and cascading water, it can bring vitality and energy, add wild charm, and enhance the landscape effect. In the south it is an excellent ground cover plant, and it is also suitable for potted ornamental viewing in the north; it is an ideal covering material for the surface of orchid pots.
