Sedum morganianum, the donkey tail or burro's tail, is a species of flowering plant in the family Crassulaceae, native to southern Mexico. It is a succulent perennial producing trailing stems up to 60 cm (24 in) long, with fleshy blue-green leaves and terminal pink to red flowers in summer. S. morganianum has been found wild in two ravines at Tenampa county, in central Veracruz, in eastern Mexico and on vertical cliffs of igneous rock in the Tropical Deciduous Forest zone. Due to its restricted geographic distribution, it should be regarded as a micro-endemic species.
