Horticultural Group

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: These tender, short-lived but low-maintenance chrysanthemums are bred to provide a burst of colour as a houseplant. They tend not to re-bloom so are best treated as a cut flower

How to Grow

Cultivation

Pot up cuttings in spring, and restrict to three stems per plant. Stake and feed regularly. Put outside in a sunny position once danger of frost is past. For large blooms, disbud. Bring pots into frost-free conditions as it gets colder. After flowering, reduce watering, cut back and store in frost-free conditions. See chrysanthemum cultivation

Propagation

Propagate from basal cuttings taken in early spring
