Dwarf evergreen shrubs with smooth brown to red-brown peeling bark.The dark green shiny leaves are typically glaucous white on the lower surface.The small flattened bell-shaped flowers (early to mid-spring) are greenish yellow to deep yellow.A choice species rarely seen in cultivation.This is similar to, but quite distinct from the plant we have sold for years here at the RSF as sulfureum (1974/108 – now known to be R. dekatanum).Requires excellent drainage.True sulfureum is native over a wide range of SE Tibet, Upper Burma and W Yunnan, China.It grows on cliffs and rocks or as an epiphyte from 7,000 to 13,000 ft.
1974/107(+20).Open upright habit displays smooth brown bark, deep sulfur-yellow flowers.
1974/108GLE (+5).Sulfur-yellow flowers with smooth brown peeling bark.
1998sd501CCHH#8236:RSBG(0?\R2\3).Deep green leaves highlight the deep yellow, flattened bell-shaped flowers in early to mid-spring.A choice species with beautiful smooth and peeling brown bark.Requires excellent drainage.Grown from my collection of seed at 11,000 ft. on the Cang Shan in W Yunnan, China.
