Discussion | Cliffs, rocky slopes, on basalt or limestone. Flowering Apr–Jul. 50–1800 m. BW, Col, ECas, Lava, Owy. ID, WA. Native. Sedum leibergii is a small, yellow-flowered Sedum like S. lanceolatum, S. radiatum, or S. stenopetalum. Unlike those species, S. leibergii has distinctly glandular-pustulose follicles. Additionally, S. leibergii does not produce offsets in the axils of stem leaves like S. stenopetalum. |
