Dwarf Rhododendron Blue Diamond Rhododendron Blue Diamond is an evergreen rhododendron that belongs to the family of Dwarf Lepidote Hybrids which owe their name to the scale-like texture of the undersurface of the foliage. Low-growing and highly decorative, this semi-dwarf evergreen shrub produces masses of violet-blue small flowers in clusters between April and May. The shades of blue tend to vary (adding to their charm) and are borne up to 5 in a truss. The evergreen foliage consists of elliptic, azalea-like leaves which start out medium green and turn to a bronze-greenish in the autumn.
A UK native, this dwarf rhododendron was hybridized in 1935, by J. J. Crosfield of Embley Park, England.

How To Care For Dwarf Rhododendron Blue Diamond Undemanding and adaptable, Blue Diamond Rhododendron does not need much to thrive in your garden. Unlike other rhododendron varieties that do well in shade, owing to its origin, this alpine shrub will do best in full sun so pick a sunny spot in the garden. However, a trait that Blue Diamond shares with other rhododendrons is that it requires well-drained, acidic soil to grow in. For best results, enrich the soil with ericaceous feed if you are unsure about the pH value or want to enhance the acidity.
