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

Acers in this dissectum group have fine, feathery, deeply divided leaves with finely serrated edges

How to Grow

Cultivation

Grow in a place sheltered from cold drying winds and from late frosts, in full sun where its colours will develop best or in light dappled shade, in moist but well-drained neutral or acidic soil that does not dry out in summer or become waterlogged in winter, and protect roots with an open-textured organic mulch such as coarse bark; for more advice, see Japanese maple cultivation

Propagation

Propagate by grafting in late winter, or by budding in summer; semi-ripe cuttings, hardwood cuttings, or layering may also be successful
