Add elegance to your landscape all year round with this evergreen shrub. The Azalea Gretel produces dark green foliage and masses of frilly, double, cerise pink and white bicoloured flowers that bloom in spring. It is ideal for pots on shady patios, garden beds and as a flowering carpet underneath trees. Whilst most azaleas prefer dappled light or afternoon shade, some will tolerate full sun exposure. Azaleas perform best in acidic soils and for this reason, there is no need to add lime to your soil.
