Sedum Flower bud

Sedum is flowering plants, many people used for ornamental plants , planted in the yard. Sedum is a large genus of flowering plants in the family Crassulaceae, members of which are commonly known as stonecrops. The genus has been described as containing up to 600 species  of leaf succulents that are found throughout the Northern Hemisphere, varying from annual and creeping herbs to shrubs. The plants have water-storing leaves. The flowers usually have five petals, seldom four or six. There are typically twice as many stamens as petals.
A number of species, formerly classified as Sedum, are now a separate genus Hylotelephium. Well known European Sedums are Sedum acre, Sedum album, Sedum dasyphyllum, Sedum reflexum (also known as Sedum rupestre) and Sedum hispanicum. (https://en.wikipedia.org/wiki/Sedum)
