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: Ground Cover roses are low, spreading shrubs with small, glossy leaves and clusters of single or double, occasionally slightly fragrant, flowers in summer, usually repeat-flowering

How to Grow

Cultivation

Grow in fertile, humus-rich, moist but well-drained soil in full sun. Mulch with well-rotted organic matter in late winter or early spring, and for best flowering apply a general rose or shrub fertiliser in early spring and again in early summer. See rose cultivation

Propagation

Propagate by hardwood cuttings in autumn, softwood cuttings (under glass) in spring or summer or by chip budding in summer
