Calsap Rhododendron is an evergreen shrub known for its stunning clusters of lavender-white flowers with a striking dark purple flare on the upper lobe. Its emerald green foliage remains lush and vibrant throughout the year, even in winter, as it holds on for two full seasons. This rhododendron thrives in full sun, which promotes a denser growth habit and encourages prolific blooming, typically starting in mid to late season, around late May to early June. It requires well-drained, rich acidic soil for optimal health and performance
