Blue flowering rhododendrons
We've hand-picked the best blue-flowering rhododendrons, which are perfect for incorporating into planting schemes of cooler colours such as violets, purples, teal and mint greens or, alternatively, using as a contrast by inter-planting between more vibrant reds and yellows to soften and temper down their intensity. Blue rhododendrons are part of the wider group of acid-loving, spring-flowering bushes which have been mainstays of woodland-style planting schemes for decades. They're grown for their abundant clusters of spectacular, showy flowers, produced above an impressive structure of spirally arranged, typically evergreen, large leathery leaves. Rhododendrons are generally larger than Azaleas, preferring a sheltered, shaded spot in a moist, acidic soil in dappled shade, protected from cold, drying winds. Smaller and dwarf rhododendrons are well-suited to growing in containers, whilst larger specimens are ideal for informal, woodland-style or naturalistic schemes. Incorporate plenty of ericaceous compost when planting and keep well watered, using rain water where possible, especially in hard water areas where tap-water contains calcium that will neutralise their preferred acidic soil.
