The plant height is generally 5-50 cm, the stem is upright or creeping in growth, and the meat of the whole plant is good. The leaf surface has wax powder, pores sink, transpiration can be reduced, pollution resistance is strong, and dust retention capacity is achieved. The plants consume little water and fertilizer, the landscaping varieties have the characteristics of cold resistance, barren resistance and drought resistance, and part of varieties can bear the low temperature of 20 ℃ below zero and can overwinter in the open field in the northern China. The world is widely distributed, and more than 1500 plants in the same genus are distributed. The main cultivation varieties at present comprise different varieties of sedum aizoon, sedum notoginseng, sedum germanica, sedum decumbens, sedum lineare and the like, and the sedum aizoon is short, small and wind-resistant, does not need a large amount of water and fertilizer, has low requirements on soil environment and good ornamental value, and is a preferred plant for roof greening, square ground greening, ground greening and slope protection, flower beds, flower mirrors, hanging baskets and tree pools.
The Crassulaceae plants are mainly subjected to vegetative propagation, mainly include branch cutting propagation, leaf cutting propagation, plant division propagation, tissue culture propagation and the like, and mainly include cutting and plant division propagation. The cutting propagation by utilizing the cutting shoot generally needs the cutting shoot with the length of 2-10 cm and at least 2 pairs of blades, the cutting depth is 1-4 cm, propagation materials such as a substrate, a plug tray, a nutrition pot, rooting powder and the like need to be purchased, strict and effective control on air temperature, humidity, plant diseases and insect pests, illumination, fertilization and the like needs to be kept in the cutting process and management after cutting, and the method is mainly used for promoting the cutting shoot to root until seedling is formed. The method adopts the leaf cuttage, the fineness of management after the cuttage directly influences whether the leaf can successfully take root, and stricter requirements are made on the propagation condition control.
