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: Sibirica irises are rhizomatous perennials, to 1.2m tall, with narrow leaves and erect stems bearing up to 5 beardless flowers 6-7cm wide in early summer. Form and colour vary considerably among cultivars
