Originally known as ‘The Low Growing Rose Tree’ the Rhododendron is the national flower of Nepal so if you’ve climbed Mt Everest and want a touch of the Himalayas in the garden, here’s your ideal plant. One of the delights of spring, the flowers are large, spectacular, and come in beautifully blended subtle colours. Hardy, easy to grow and loving part shade, all they really need is consistent moisture with good drainage.
