An evergreen to semi-evergreen shrub in the heath family, a garden cultivar created in Edo-period Japan with putative hybrid origins involving Kerama azalea. The 8–10 cm bright reddish-purple flowers are exceptionally large for an azalea — hence 'ōmurasaki' ('big purple'). Widely planted in parks, streetscapes, and hedges across Japan, it defines early-summer azalea displays. The inner upper petal bears darker nectar-guide spots.
