Knapp Hill rhododendron | Deciduous azaleas are probably the most striking flowering shrubs. Their colours are vivid and bright, and often have the shades that not many rhododendrons can offer. They need full sun. “Arneson Gem” is a true jewel. Its reddish buds open to soft golden-yellow flowers with apricot orange tips and petal margins. It is fragrant and the leaves are disease resistant. Prolific bloomer.

Deciduous azaleas are ericaceous plants, loving insulate position with always moist soil. During temporary summer dry spells in certain areas their leaves may be weak. They require no pruning. Should you need to shape or rejuvenate your plant do so as early in the spring as possible so that it can still make new twigs with flower buds for the next season. It re-sprouts reliably. It has many surface roots which spread to sides in search for nutrients and water. The best soil mixture consists of peat, lime-free compost and leaf-mould. Fully hardy.
