Overview

Compact and clump-forming, Dahlia 'Copperboy' produces striking coppery pompon blooms from summer to the first frosts. Dark stems and green serrated foliage support each ball-shaped flower, perfect for borders, containers, or cutting for vases.

Its rich bronze-orange tones contrast beautifully with whites and creams, adding long-lasting colour and texture to any garden display.

Specifications

  • Position: Full sun
  • Soil: Moderately fertile, moist but well-drained soil, or peat-free general purpose compost
  • Rate of growth: Fast-growing
  • Flowering period: July to October
  • Hardiness: Borderline hardy (will need protection in winter in colder areas)

Care guide

Dahlia tubers can be planted outside after frost, or started off in pots under glass in late winter to early spring. Plant them horizontally approximately 12cm deep, making sure the ‘eyes’ are uppermost. Allow enough room between each tuber so the plants can grow and spread to their full size without being overcrowded.

While in growth, provide a high-nitrogen liquid feed each week in June, then a high-potash fertiliser each week from July to September. Stake with canes or brushwood if it becomes necessary. In mild areas, leave them in situ over winter, but protect the crown with a generous layer of dry mulch.

In colder areas, carefully lift and clean the tubers once the first frosts have blackened the foliage and allow them to dry naturally indoors. Then place the dry tubers in a shallow tray, just covered with slightly moist potting compost, sand or vermiculite and store in a frost-free place until planting out again.
