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: Dessert apples are sweet and juicy and are best eaten fresh and raw

How to Grow

Cultivation

Prefers deep, fertile, moist but well-drained, neutral soil in a sunny sheltered position. Will not thrive on very acid soils, shallow chalk soils or with shade for more than half the day. Ideal for containers. May require fruit thinning to improve fruit size and quality. See apple cultivation

Propagation

Propagate by chip budding in late summer, or grafting in mid-winter. Plants grown from pips are unlikely to resemble the parent
