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: Medium-flowered Indoor Incurved chrysanthemums have spherical, fully double flowerheads with florets curving upwards, borne in late autumn

How to Grow

Cultivation

Grow in a sheltered site in full sun in fertile well-drained soil, enriched with organic matter and general purpose fertiliser. Water freely in dry weather. Pinching out the growing tip when the plants are 15-20cm tall to encourage free flowering bushy plants. Staking is usually required. There is no need to deadhead. In mild areas leave in the ground protected by a thick mulch. Elsewhere lift the crowns and store in a greenhouse, raising fresh plants from these each year

Propagation

Propagate by rooting softwood cuttings in peat-free potting compost at 16°C in spring. Pot on rooted cuttings in late June to early July into 23cm pots and pinch out as soon as established
