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

Dahlia ‘Sunset Kate (Sin) = Single flower
Rosa ‘Marigold’ (HT) = Hybrid Tea: Tuberhybrida begonias are bushy tuberous perennials with glossy leaves and usually double flowers in small clusters in summer; most are dormant in winter
Plant Range: China

How to Grow

Cultivation

Thrives in fertile, humus-rich, well-drained neutral to acid soil, in dappled or afternoon shade. May need winter protection in colder regions, and can be slow to start in spring. Will not tolerate waterlogging. See begonias: outdoors for further information

Propagation

Propagate by basal softwood cuttings in spring, or by seed; plants will often self-seed, dropping tiny bulblets from the stems in late summer
