Rhodiola coccinea (scientific name: Sedum sperum cv. cocininium), a plant of the genus Sedum of the family sedaceae, perennial herbs; native to the caucasian region. The common stonecrop herb is a crassulaceae plant introduced abroad in recent years, has extremely strong early resistance, is short and 10-20 cm high, has a florescence of more than 6-9 months, flowers red, and leaves are carmine red. Sedum lineare (Sedum mexicanum Britt), perennial herb; the four-leaf impeller grows from the infertile branch and grows alternately to the pregnant branch, and is often dense; the leaf shape is needle-shaped, the meat is fleshy, the shape is cylindrical, the whole edge is 5-20 mm long, the width is 1-3 mm, the leaf tip is gradually sharp, and the leaf base is narrow and wedge-shaped. Yellow flower, parasol inflorescence; sepals are not equal in length; the fruit stands upright.

The sedum cochinchinense and sedum lineare are Crassulaceae plants, have close relationship between families and have better mixed sowing performance. The sedum carmichaeli and sedum lineare have the characteristics of heat resistance, drought resistance, barren resistance and the like, so that the sedum carmichaeli and sedum lineare are widely planted and applied to roof gardens. However, the stem and leaves of the sedum cochinchinensis and the sedum pinifolium are meat and especially cannot resist long-term waterlogging, so the method for simultaneously cultivating the sedum cochinchinensis and the sedum pinifolium is a problem to be solved by the technical personnel in the field.
