Hypericum androsaemum, the shrubby St. John's wort, is a flowering plant in the family Hypericaceae. Commonly called tutsan or sweet-amber, the species is cultivated as an ornamental plant because of its striking red-tinted foliage, bright yellow petals, and its large clusters of fruit. Cultivars like 'Albury Purple' and 'Golden Tutsan' which have leaves with more pronounced purple and golden coloring, respectively.

Androsaemum, commonly called tutsan, is a section of flowering plants in the family Hypericaceae. It is made up of Hypericum androsaemum, H. foliosum, H. grandifolium, and H. hircinum, as well as the hybrid H. × inodorum. When it was first described, it was considered its own independent genus, but was later placed under Hypericum and demoted to a section. It is also the namesake of an "Androsaemum-group" of related taxa that includes several other sections of Old World species. The Latin name Androsaemum comes from a Greek work to describe plants with red sap, and literally means "blood-man".
