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

This genus produces fruit, but not necessarily edible fruit

How to Grow

Cultivation

Grow in moist well-drained slightly acidic soil in a sheltered position in full sun although can tolerate light shade but the yield will be reduced. Grow in rows between parallel wires for support. Mulch with acidic material such as composted bark. May have the potential to become a nuisance if not managed well. See raspberry cultivation

Propagation

Propagate by division in the dormant season. Lift new canes along with their rootballs. Choose only newly planted, disease-free stock from which to propagate

Suggested planting locations and garden types

  • Cottage and informal garden
  • Wildlife gardens
  • Edible fruit
  • Hedging and screens

Pruning

Cut back all stems that have fruited, in autumn and train in new growth ready for the following summer's fruit

Pests

May be susceptible to aphids, leafhoppers, raspberry beetle, glasshouse red spider mite and gall mites

Diseases

May be susceptible to grey moulds and honey fungus (rarely)
