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: Fimbriated dahlias have splits in the tips of the florets and no visible central disc, giving them a soft, feathery texture

How to Grow

Cultivation

Plant tubers 10-15cm deep in fertile, humus-rich, well-drained soil, in full sun. Cut back to near ground level in mid-autumn. In mild areas, and on well-drained soils, leave the tubers in the ground and protect with a deep, organic mulch. In colder areas, or on heavy soils, lift and store the tubers and replant in late spring after all danger of frost has passed. See dahlia cultivation and our video How to plant dahlia tubers and care tips

Propagation

Propagate from softwood cuttings in spring taken from stored tubers or divide the tubers ensuring each division has a viable bud

Suggested planting locations and garden types

Cottage and informal garden
Patio and container plants
Flower borders and beds

Pruning

Deadhead to prolong flowering; cut back to the ground in autumn and either lift and store for the winter or mulch well and leave in place in milder regions

Pests

May be susceptible to aphids, capsid bugs, earwigs, caterpillars, slugs, glasshouse red spider mite and onion thrips

Diseases

May be susceptible to a virus; tubers may rot in storage
