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

Polyanthus group primulas are rosette-forming perennials with umbels of salver-shaped flowers. They are usually grown as biennials by sowing seed in summer and planting out in autumn for flowers in winter and spring.
