Rhododendron eriocarpum

Rhododendron eriocarpum or commonly called Marba-satsuki(Japanese) (scientific name: Rhododendron eriocarpum) is a cold-resistant evergreen shrub of the family Ericaceae. It grows naturally on lava plateaus and rocky coastal areas from southern Kyushu to the Ryukyu Islands. Its other name, "Kaimon satsuki (satsuki azalea)", is derived from the fact that it grows naturally on Mt. Kaimon dake. The shrub height is 50 to 150 cm. The leaves are more rounded than those of the common satsuki (scientific name: Rhododendron indicum). The flowers bloom from May to June and are small, 3 to 5 cm in diameter. The name of the flower comes from the rounded leaves of the satsuki. It is considered to be the original species of the garden satsuki.
