Yason is the whole grass of the Sedum lineare of the Crassulaceae family. It is mainly distributed in Shanxi, Shaanxi, Gansu, Henan, Hubei, Sichuan, and Yunnan, and has the effect of clearing heat and detoxification. Let's learn about the application value and propagation methods of Yason below.

【Morphological characteristics of Yason】
Yason is an annual herb with no hair and has a fibrous root. The stem is solitary or tufted, 5-30 cm tall. The leaves are arranged in whorls of 3-5, elongated spoon-shaped, 8-20 mm long, 2-4 mm wide; the apex is sharply pointed, the base is gradually narrowed, the margin is entire, and it has no or very short stalks. The inflorescence is conical or umbel-like, with long branches, and the axils of the lower leaves also bear inflorescences, with sparse flowers; the flower stalk is 5-8 mm long, slender; the sepals are 5, narrowly triangular to lanceolate; the petals are 5, white, rectangular-ovate; the stamens are 10, with wide spatulate scales and deep notches at the top; the carpels are 5, nearly erect, fused at the lower part, with small nipple-like protrusions. When fully mature, the upper half is obliquely spreading, with a few small seeds.

【Application value of Yason】
Aged Yason has a similar color to Yacypress, ranging from gray-black to gray-white. Yason that comes out of the cliff cavity also has a thick coating of nearly a centimeter, and its shape varies from lump to plate.
The oiliness and delicacy of Yason are very good, and the woody part has a color ranging from light yellow to golden red, which can carve out very delicate texture. Personally, I think it is no less than any other existing root art material.
As a root art collection, the most outstanding feature of Yason is its beautiful and diverse texture. As mentioned earlier, Yason's texture is larger, three-dimensional, and full of strength; combined with its skin color and unique texture, it is quite impactful. Moreover, the shape is also varied, just like Yacypress, with distinct figures of people and birds and animals. It is definitely a natural root art material worth collecting.

【Propagation methods of Yason】
1. Division propagation
Yason can be divided except in winter. Simply separate the offshoots that grow from the base of the mother plant, with 2-4 buds per clump, and split them from the rhizome. After the cut is slightly dry, plant it in a suitable pot and keep it in a shaded place for a period of time before transferring it to normal cultivation management.
2. Seed propagation
Generally used for cultivating new varieties. It can be done in early spring. The seeds are covered with a thin layer of soil and kept at 15-18°C, and they will germinate in 3-5 weeks. After 1-2 true leaves grow, transplant them into pots.
3. Cutting propagation
It can be done during the growing season. Cuttings can be taken from April to September. Cuttings of 2-5 cm long are taken, the cut end is dried for 2-5 days, and then inserted into a propagation bed. Keep it in a shaded environment, and it can be propagated after rooting. When the leaves are larger, leaf cuttings can also be used, but the cut end must be dried before cutting.
