Irene Koster is a multicolor fragrant deciduous azalea with exceptionally beautiful blooms. It's incredible flowers show off an array of white, pink, and yellow each spring. Blooming can occur across April-June depending on growing conditions (our bloom photos were taken near the end of April). These plants are an eye-catcher and they provide a lovely fragrance to gardens when blooming.
Irene Koster is a large grower that reaches around 6' tall x 6' wide at maturity. These deciduous azaleas like plenty of sun, but afternoon shade can be beneficial in hot climates. Hardy to -15°F when protected against windchill.
