How to grow

Cultivation

Plant tubers 10-15cm deep in fertile, humus-rich, well-drained soil in full sun. Cut back to near ground level in the autumn, then, in mild areas and on well-drained soils leave the tuber in the ground protected with a deep organic mulch; in colder areas or on heavy soils, lift and store the tubers; see dahlia cutlivation

Propagation

Propagate from softwood cuttings in spring taken from stored tubers or divide the tubers ensuring each division has a viable bud

Suggested planting locations and garden types
  • Cottage and informal garden
  • Patio and container plants
  • Flower borders and beds
Pruning

Deadhead to prolong flowering; cut back to the ground in autumn and either lift and store for the winter or mulch well and leave in place in milder regions

Pests

May be susceptible to aphids, capsid bugs, earwigs, caterpillars, slugs, glasshouse red spider mite and onion thrips

Diseases

May be susceptible to a virus; tubers may rot in storage
