Azalea, part of the Rhododendron genus, is an ornamental shrub widely popular for its vibrant, beautiful flowers that typically bloom in the spring. Originating from different regions, there are two main types: the evergreen Asian species (Rhododendron simsii), native to Japan and China, and the deciduous North American species (Rhododendron canescens and Rhododendron viscosum among others). Azaleas are commonly found in light woodland areas across Asia, Europe, and North America. The plant enjoys a cool climate with well-drained, acidic soil. Possessing a multitude of leaf shapes and sizes, Azaleas are typically small- to medium-sized shrubs, sometimes growing as higher as 20 meters. The foliage colors can be deep green, light green, or even purple or bronze, while the lush blossom includes a palette of colors from white, pink, and red to purple, orange and yellow. Azaleas captivate with their stunningly explosive bloom, where a healthy plant might be entirely covered in flowers. In terms of aesthetics, Azaleas are a popular choice for gardens, often respected as "royalty of the garden". On top of their visual beauty, many species also offer a pleasant fragrance attracting pollinators. Interesting cultural notes: In Chinese culture, Azalea is known as the "thinking of home bush" (思乡树) and symbolizes homesickness. In Japan, it represents patience and modesty. Moreover, several cities around the world, such as Nezu, Japan, and Wilmington, North Carolina, USA, celebrate annual Azalea festivals showcasing thousands of colourful Azaleas in full bloom.
