"cultivation": "Grow in fertile, humus-rich, well-drained soil, enriched with organic matter, in full sun. Pinch out growing tips to encourage bushy plants and stake - see staking perennials. Water as needed in dry periods. Lift and store tubers in autumn to replant, or use as a source of cuttings, in spring. See dahlia cultivation and our video How to plant dahlia tubers and care tips",
"pruning": "Deadhead to prolong flowering. Cut back to near ground level in autumn, once frost has damaged foliage, before lifting and storing for the winter",
"propagation": "Propagate by softwood cuttings taken in spring from shoots from stored tubers, or divide the tubers, ensuring each section has at least one viable bud",
"pests": "May be susceptible to aphids, capsid bugs, caterpillars, earwigs nibbling flowers, glasshouse red spider mite and slugs",
"diseases": "May be susceptible to powdery mildews in dry conditions, fungal rots including grey mould in wet conditions and in storage, and a virus that causes stunting, leaf markings and distortion",
"description": "A tuberous-rooted perennial to about 1m, with mid-green foliage. The flowers, appearing from mid-summer until the first frost, are large, up to 25cm across, but neatly formed, in a soft, bluish-pink",
