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: Shrub roses are large shrubs with usually thorny stems bearing large leaves and fragrant, single to double flowers in clusters in summer, and usually also in autumn
Plant Range: Himalaya, W China

How to Grow

Cultivation

Suited to a wide range of situations but best in an open site in full sun, where the ruby-red young thorns can be appreciated. Grow in moderately fertile, humus-rich, moist but well-drained soil - see rose cultivation. Tolerant of poor soil and shade

Propagation

Propagate by hardwood cuttings in late summer or autumn or by chip budding in summer. Propagate by seed; species roses can be propagated by seed but need stratification and germination may take two seasons

Suggested planting locations and garden types

Coastal
Cottage and informal garden
Wildlife gardens
Hedging and screens

Pruning

See pruning group 20 (shrub roses); spring flowering, prune immediatley after flowers have faded, but do not deadhead flowers if fruit (hips) are needed
