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: Pinks are hardy, evergreen perennials which make compact mounds or mats of usually greyish leaves, with up to six, usually fragrant, single or double, medium-sized flowers per stem in early and mid-summer

How to Grow

Cultivation

Grow in full sun in moist but very well-drained, gritty, neutral or acidic soil (unlike many other species & cultivars, which prefer alkaline soil), in a rock garden, a sink or trough, or an alpine house; protect outdoor plants from damp in winter, for example with a propped pane of glass

Propagation

Propagate by cuttings from non-flowering shoots in summer, by layering, or by division
