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: Division 13 daffodils include all natural species and their varieties and forms

How to Grow

Cultivation

Plant at one and a half to two times the depth of the bulb in autumn. Will tolerate most soils but prefers moderately fertile, well-drained soil that is constantly moist during the growing season. See daffodil cultivation for further advice

Propagation

Propagate by division, removing offsets as the leaves fade in early summer, or by chipping. See bulb propagation for details
