This variety belongs to a group that includes hybrids of Rhododendron japonica and Rhododendron nakaharae. These are generally dwarf in habit, most growing much wider than high. All are prolific in flower, producing masses of delicate, funnel shaped flowers during April and May, against a foil of evergreen foliage. They are charming subjects for a shaded small garden or woodland planting.

They are ericaceous plants i.e. they require acidic to neutral soils (pH7 or lower) and generally will not thrive in more alkaline conditions (i.e. high in lime, pH7.5 or higher). Being woodland plants, they require moist but well drained soil that is rich in organic matter as well as the dappled shade and shelter of other trees and shrubs. They are also useful subjects for a sheltered North facing border.

Rhododendrons are surface rooting and have very fine roots so extra care is needed when planting, adding in plenty of organic matter (such as leaf mould, peat or good quality ericaceous compost) to the planting area to form a nice friable mixture. They will not thrive if planted too deeply so keep to the same depth as your plant is growing in its pot. Water the plant thoroughly and ensure the plant is thoroughly soaked at its roots at all times during any dry spells.

    I rarely write reviews but I must recommend this excellent nursery. It is the best nursery I have used for online ordering. Rang them first with some questions and they were most helpful. Then did my order of heathers and they were sent and arrived promptly in great condition and are very healthy looking plants.
