Sedum lineare, commonly known as carpet sedum, needle stonecrop or sea urchin, is a sedum originating in East Asia and is a perennial flowering plant in the family Crassulaceae.
The family of stonecrop succulents is large and encompasses low growing, trailing plants and tall spiked-flowering plants that may get up to a foot (31 cm.) in height. All stonecrop plants have a rosette form and most produce a flower held above the base foliage. The leaves are thick and semi-glossy.
Stonecrop doesn’t have a deep root system and can be buried shallowly in soil. They cannot tolerate competition from weeds and other plants, but a mulch of small stones helps minimize such pests. The plants need well-drained soil that is rich in organic amendments. Young plants should be watered every few days while establishing but irrigation can diminish thereafter and no supplemental water is needed in fall and winter. If planting in containers, use pots that are unglazed clay to promote evaporation of excess water. Overwatering is the most common cause of problems in stonecrop
