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

Cal-Sib irises are derived from hybrids between Pacific Coast types and Siberian irises, and are rhizomatous perennials with narrow, usually evergreen leaves and one or two beardless flowers per stem
