A luxurious, purple dahlia, Decorative Dahlia 'Thomas A. Edison’ bears bountiful, rich velvet blooms over several months. Petal edges lighten at their borders, making the opulent blooms look breathtaking when backlit with sunshine.
The huge flowerheads are impactful, both in the garden and in flower arrangements. Tall, sturdy stems hold the fully-double flowers proud and upright in the border. Grows to a height of 100 cm.
A wonderful dahlia for cutting and adding a vivid ruffle of texture to large-scale displays. Combine decorative dahlia 'Thomas A. Edison' with gemstone colours, such as ruby, amber and amethyst for a rich display.
de Jager's top size, top quality dahlia tubers are supplied polythene bags, in which they may be safely kept until planting time, stored in a cool place.
To grow Dahlias, select a sunny spot with well-drained soil, and dig a 30cm deep hole. Plant the tuber 10cm below the soil surface, spacing multiple tubers 45cm apart, or 90cm for taller varieties. Water consistently, maintaining moist but not saturated soil and protect new shoots from slug damage with eco-friendly methods. Feed plants during the blooming period with liquid plant food. Provide support for stems which will reach 60-90cm tall depending on variety. Enjoy spectacular blooms from late summer until first frosts. Cut or deadhead the flowers regularly for a continually flourishing display. Once blooming has finished, cut back foliage before lifting, drying and storing the tubers in peat-free substitute, in a frost-free place until the following spring.
