Easy going, looks good - essentially it's a Golden Retriver

It's a great plant for the garden, it's hardy and will tolerate the cold winter weather, and it's very attractive; as well as the great show of flowers, the foliage turns to super colours in the autumn, orange, purple and red. It grows dense and bushy and will grow between two and four metres in both height and spread. The flowers give off a strong and pleasant fragrance. If you have moist acidic soil you should find this azalea easy to grow.
