Purple is a popular colour in the garden as it adds a feeling of solidity to the colour palette as well as blending easily with a wide range of other shades. The dahlias in this collection all flower prolifically over several months from midsummer and will make excellent and long-lasting additions to the vase. They are not fully hardy, however in many areas they can be overwintered in the ground as long as they are protected by a generous, insulating mulch of compost or straw. Alternatively you should wait until the first hard frost has blackened the flowers and foliage, then lift the tubers and store them in dry sand in a frost-free place. In colder areas it may be easier to grow them in a pot so they can easily be moved to an unheated greenhouse or conservatory in winter.
In each collection you will receive one tuber of each of the following cultivars.
- Dahlia 'Thomas A. Edison'
We wanted this decorative dahlia in our collection as its flower colour is so easy to mix with a wide range of other shades. The many-petalled, medium-sized blooms are crammed with magenta pink petals, which tend to be a touch paler towards theit outer edges. They are also excellent for cutting, which will encourage more to form. Grows to 100cm.
- Dahlia 'Purple Gem'
This rich-purple, cactus-shapped dahlia will flower from midsummer to mid-autumn, particularly if the spent flowers are removed promptly - or you cut them fresh for the vase. The magnificent flowerheads look incredible when mixed with rich plums, deep purples and near-black. Grows to 120cm.
- Dahlia 'Rocco'
A classic for the cottage garden, with lilac-purple pom poms (up to 5cm across), that bob and sway happily on their slender stems. Mix it with pale pinks and purples or rich plums and plant more than you need so you have a constant supply for the vase. Grows to 75cm.
- Garden care: 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.
