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: Rambler roses are vigorous shrubs with long, arching, thorny or smooth stems carrying glossy foliage and large sprays of small, single or double, often fragrant flowers in early summer
Plant Range: Central and E China

How to Grow

Cultivation

Grow in fertile, humus-rich, moist but well-drained soil in full sun, in a warm sheltered position. Best suited to southern counties. Good for climbing into large trees. Mulch with well-rotted organic matter in late winter or early spring, and for best flowering apply a general rose or shrub fertiliser in early spring and again in early summer. See rose cultivation

Propagation

Propagate by softwood cuttings in early to mid spring, hardwood cuttings in late summer to autumn or by chip budding in summer; propagate by seed; species roses can be propagated by seed but need stratification and germination may take two seasons
