Horticultural Classification Codes

Horticultural Classification Codes are often given to genera which have a large number of species or cultivars. They are used to categorise cultivated plants based on specific, shared characteristics such as shape, colour, size or flowering time, and can be displayed as letters or numbers

For example:
Dahlia ‘Sunset Kate (Sin) = Single flower
Rosa ‘Marigold’ (HT) = Hybrid Tea: Evergreen azaleas are compact evergreen shrubs with small leaves and terminal racemes of small, funnel-shaped, usually unscented flowers in early summer

How to Grow

Cultivation

Grow in moist but well-drained, leafy humus-rich, acid soil in part shade with shelter from cold winds, ideal for a woodland garden; sun tolerant if soil remains reliably moist but strong sun may bleach flower colour; see rhododendron cultivation. If growing indoors, place in a cool, light well-ventilated spot out of direct sunlight. See rhododendron cultivation for further advice

Propagation

Propagate by semi-ripe cuttings in late summer, layering in autumn or grafting in late summer or late winter

Suggested planting locations and garden types

City and courtyard gardens
Cottage and informal garden
Patio and container plants
Flower borders and beds

Pruning

Deciduous rhododendrons respond well to hard cutting back. After cutting back, mulch, feed if soil conditions are poor, and keep well-watered to encourage new growth

Pests

May be susceptible to vine weevil, rhododendron leafhopper, pieris lacebug, scale insects, caterpillars and aphids

Diseases

May be susceptible to Rhododendron diseases, powdery mildews, rhododendron petal blight, rhododendron bud blast, silver leaf and honey fungus
