Overview

A delightful, bicoloured collarette dahlia with sturdy, upright stems and large flowers with pink outer petals encircling a creamy white collar of shorter inner petals, creating a striking contrast against the dark green foliage. Blooming from mid-summer until the first frosts, whether selected for the border, a patio pot or as a cut flower for the vase, this pollinator-friendly tuberous perennial promises a vibrant and eye-catching display throughout the growing season.

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 over-crowded. 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.
