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: Hortensia hydrangeas (also known as mopheads) are compact bushy deciduous shrubs with broadly ovate leaves and rounded flower clusters composed almost entirely of showy sterile flowers

How to Grow

Cultivation

Grow in any moist but well-drained soil in partial shade or grow in sun if soil remains reliably moist. Improve chalky soils with organic matter to support good growth. See shrubby hydrangea cultivation for further advice

Propagation

Propagate by softwood cuttings in early summer, or hardwood cuttings in winter. As this plant is protected by Plant Breeders' Rights, any propagation should be for personal rather than commercial use
