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: Ivy-leaved pelargoniums are evergreen perennials of trailing habit, with fleshy, palmately lobed leaves and clusters of showy red, purple, pink or white flowers from early summer to autumn
