Azalea japonica 'Radja' is a compact evergreen azalea grown for its striking scarlet-red spring flowers and neat, low-growing habit. In mid spring, masses of vivid blooms appear close to the foliage, creating a dense blanket of colour that gives the plant strong visual impact despite its modest size. The flowers contrast sharply with the glossy dark green leaves, which remain attractive throughout the year. Naturally well shaped and easy to maintain, 'Radja' is ideal for containers, low borders, or ericaceous planting schemes where bold colour and evergreen structure are required.
