Rhododendron - probably arboreum/catawbiense hybrid
Hardy, medium sized evergreen shrub with dense, well-branched plant habit and pointy, dull dark-green foliage. During October-November, gorgeous trusses of funnel-shaped, magenta-lilac blooms emerge to provide a stunning show of colour.
Prefers dappled sun and requires well-draining, humus-rich, acidic soil.
