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

Zonal pelargoniums are bushy evergreen perennials with fleshy stems, rounded, palmately lobed leaves often zoned with maroon, and single or double flowers in shades of purple, red, pink, orange and white, from early to late summer
