Japanese azalea Johanna

The 'Johanna' Japanese Azalea, also known as Hybrid Rhododendron, is an evergreen upright shrub that stands out with its deep red flowers and dark green foliage. It will brighten up your borders and pots.

Originally from Japan, the 'Johanna' Azalea forms a small, dense bush with an upright habit, reaching 60 cm (23.6 in) in height and 50 cm (19.7 in) in width at maturity. Its persistent, ovate, glossy, and leathery leaves are dark green, turning purple in autumn. During the months of April and May, this small bush produces numerous trumpet-shaped flowers with a diameter of 5 cm. They are beautifully coloured in deep red. A highly anticipated event in the garden.

Hardy down to -17°C, the 'Johanna' Japanese Azalea prefers a bright exposure and should ideally be planted in partial shade, in a location protected from cold and dry winds. Slow growing, this small bush that thrives in cool, humus-rich, well-drained soil with acidic tendencies.

The 'Johanna' Azalea dresses up heathland borders all year round and brings gardens to life in spring with its colourful flowers. Plant it on a slope, in a shady rock garden, or at the edge of a border alongside Pieris, Heather, Kalmias, Andromedas, Chinese Azaleas, and Japanese Maple.

Divided into 2 horticultural groups, the Rhododendron genus includes, on one hand, both Chinese and Japanese Azaleas, with small persistent or deciduous leaves, each flower having 5 stamens, and on the other hand, Rhododendrons, with a large, persistent, glossy foliage and flowers with more than 10 stamens. Although highly debatable from a botanical point of view, this classification is still widely used by horticulture professionals.
