What is Rhododendron dilatatum

Rhododendoron dilatatum or Mitsuba tsutsuji (scientific name: Rhododendoron dilatatum) is a deciduous broad-leaved shrub in the Ericaceae family, Rhododendron, endemic to Japan.
It is an early flowering azalea. It grows naturally in thickets on the Pacific side of the Kanto to Kinki regions. The only azalea that is toxic is the renge azalea, but all others are non-toxic. It is used for garden and potted plants.
