Rhododendron simsii is a small shrub (2–5 m) that occurs naturally in forests and forest margins at altitudes between 500–2700 m a.s.l. (eFloras) and is distributed from subtropical China to Japan, Laos, Myanmar and Thailand. It is described as shade-intolerant and self-sterile, with bee-pollinated flowers and small seeds. It is an important ornamentals with a long breeding tradition, it is a rare species in this genus flowering during summer, which provides a unique resource for floral timing breeding[1][2].
