Rhododendron 'Azurika' (Azurika Rhododendron)


Michael's Opinion

Rhododendron 'Azurika' is not a very well known plant due to it being a hybrid. As Michael Dirr stated: "Rest assured that even the experts do not know the rhododendron genus in its broadest sense" (Dirr 950). 'Azurika is a cross between R. russatum and R. impeditum. A stunning small dwarf plant, it blooms with beautiful violet flowers for an extended period of time, as well as it is fairly adaptable and quite tough to a variety of climate and site conditions.

Description and Growing Information

General DescriptionDwarf shrub, dark leaves (small), the twigs and stems are all very small and hidden in the foliage. Extremely floriferous (multiple trusses on many branches), compact growth, low growing and fairly large spreading.
ID CharacteristicA small, evergreen shrub with compact growth and small, dark-green waxy leaves. Deep purple/violet large ruffled trumpet-like flowers, appear in the late spring.
ShapeCompact, shrub, horizontal, low growing.
LandscapeUsed in shade and woodland areas because of its part sun/part shade tolerance. Due to it being a dwarf variety and its low-spreading nature, it is not the focus of a garden, but rather, a lovely accent for dimension and colour. Stunning deep purples add a nice contrast to the dark evergreen leaves.
PropagationRhododendrons can be propagated by cuttings, grafting, layering (pinning a low branch to the ground) or tissue culture.
Cultivation'Azurika' needs to be constantly moist but requires good drainage. Planting in windy areas, exposed situations and heavy shade should be avoided.
