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: New Guinea impatiens, derived from I. × hawkeri, have brightly-coloured, relatively-large flowers set against typically dark green foliage on a plant with a neat habit, typically up to 60cm wide and tall
