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

Rex begonias are evergreen, rhizomatous perennials grown for their handsome, brightly coloured leaves, rather than the small pale pink or white flowers which may appear in spring, summer or autumn
