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: Fringed Group tulips flower in late spring, with single, cup-shaped flowers with finely-fringed tepals

How to Grow

Cultivation

Plant bulbs in late autumn, at a depth of 10-15cm (4-6in) in fertile, well-drained soil. Choose a sunny position, with protection from strong winds and excess winter wet. Lift bulbs annually, once the leaves have died down, and ripen in a cool greenhouse, keeping dry over the summer. See tulip cultivation for more details

Propagation

Propagate by division, separating offsets in summer when bulbs are lifted. Replant the largest bulbs in autumn, and grow on smaller ones in a nursery bed for a year. See bulb propagation for more details
