Rhododendron 'Vulcan' is a compact variety, bearing long slender leaves and large, almost crepe-like, scarlet-red blooms with contrasting black anthers. It’s a great choice for growing in a container on a sheltered patio, but is equally suited to growing in a border.
Grow Rhododendron ‘Vulcan’ in partial shade where it’s protected from harsh winter winds. Plant in humus-rich, moist but well-drained neutral to acidic soil (or peat-free ericaceous compost). Rhododendrons are shallow-rooted so take care not to plant too deeply. Protect from harsh winter winds and mulch annually with a generous layer of leaf mould. There should be little or no need to prune.
