Overview

Experience the fiery afterglow of our red-flowering dahlia collection. This hot-themed combination showcases impressive flowerheads starting in a sumptuous shade of pink-tinted scarlet before transitioning to a warm vermilion and crimsons as the season progresses. Their vibrant hues creates a striking contrast against lush green and lacy foliage, making them a standout in any garden or charming addition to vase arrangements.

Specifications

  • Position: Full sun
  • Soil: Moderately fertile, moist, well-drained soil
  • 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.

Features

  • In each collection you will receive one tuber of each of the following cultivars:
  • Dahlia 'All Directions': Chosen for its impressive 10cm wide flowerheads, which open from bud a sumptuous shade of red, but then fade to warm vermilion as the season progresses. Its flaming colour really stood out in the trial beds - particularly when set against the backdrop of rich green foliage. Grows to 1.2m.
  • Dahlia 'Red Cap': Fire engine, or telephone box red describes the colour of this free-flowering ball dahlia. Fabulous when planted in a border with deep purple, rich orange or yellow, ‘Red Cap’ will also look dazzling against a backdrop of silvery or bronze foliage. It flowers freely from midsummer to mid-autumn, and the blooms make excellent subjects for a vase. Grows to 90cm.
  • Dahlia 'Jive': The flowerheads of this eye-catching dahlia are slightly variable, being a mixture of single or anemone-shaped, while their 'petals' are initially pink-tinted scarlet, but turn a warm orange-red as they age. Their lush green foliage, which is lacier than many other forms, is also attractive, and adds further to the appeal. Grows to 1.2m.
