In late May to mid-June, its funnel-shaped bright red flowers bloom in clusters. The flowers are especially colourful ranging from deep orange to red and measuring up to 10 cms. Long delicate stamens reach out from the centre. The flowers don’t fade and they bloom for months covering the plant and attracting pollinators. This plant may sometimes be sold as Rhododendron Nabucco due to rhododendrons and azaleas being formally classed together in the one genus to reflect their many common characteristics.
