“Cosmopolitan” brightens up every garden with its clear pink trusses of large flowers with deep purple dotted throats. Leaves are large, too, and glossy, very attractive all year round. It flowers as one of the first.
For richer flowering and growth dead-head where possible. It prefers bright to dappled shade or partial shade (partial sun). The roots are shallow, spreading to sides in search for nutrients. Never plant them too deep. The soil has to be acidic, rich in humus, cool and always moist. Ideal soil mixture is peat with lime-free, light garden soil topped with leaf-mould. Use selective fertilizers for rhododendrons only.
