The larger species rhododendrons have spectacular foliage and flower interest to offer. R. macabeanum is one of the best for the garden.
The huge pale, creamy-yellow flowers have a basal purple blotch hang in loose umbels of up to 20 blooms. The depth of flower colour can be variable. Opening in early spring they are sometimes spoiled by inclement weather. R. macabeanum will often not flower to full potential every year, but a mature plant in full bloom is a spectacular sight.
The leaves are very dark green to 45cm, with heavy veining and white indumentum underneath. The new leaves emerging from the brightly coloured bracts is a special sight.

These plants need a shady spot with a well-aerated, slightly acid and well-drained soil that does not dry out. Mulch lightly each spring to conserve soil moisture and protect from heavy frosts. Avoid planting in positions with strong or persistent winds which will scorch or tear the leaves.
Eventually a tree R. macabeanum can become quite tall and leggy when grown in shade, or wider and more shrub-like in a more open position. For those with a cooler climate and a largish-space in the garden R. macabeanum is a magnificent plant with its salmon pink new shoots and huge sculpted leaves. The creamy flowers in the early spring and are well worth waiting a year or two while your plant matures.
