Description

Dahlia genus. This genus has upright and bushy, early summer and early autumn flowering, tuberous, deciduous annuals and perennials. They bear pinnatifid or pinnatisect, mid green leaves and disc-shaped flowers.

Characteristics

Annuals or Perennials, Deciduous, Shrubs or Herbaceous

Origin

Mexico and C.America

Interest and use

Grown as bedding plants or for their flower heads, which are good for cutting or exhibition. Suitable for coastal conditions.

Cultivation

They are half hardy to hardy and will need a sunny position with well drained soil. In frost-free areas, the plants may be left in the ground as normal herbaceous perennials, but they will benefit from regular propagation to maintain vigour. After flowering in areas with frost, lift tubers and store in a frost-free place; replant once all frost danger has passed.

Propagation

Propagate dwarf forms by seed sown under glass in late winter, others in spring by seed, basal shoot cuttings or division of tubers.

Pests, diseases or disorders

Subject to attack by aphids, red spider mite and thrips; they can also succumb quickly to virus infection.
