While you may have a perception of dahlias as being old-fashioned, and something that your grandad grew when you were younger, they have actually been enjoying a renaissance over the last few years, mainly because they provide such stunning colour and value for money in the late summer and autumn. So easy to grow, Dahlias are supplied as tubers, packed full of energy to burst into growth in spring. Plant in pots or in the garden and they will get away quickly from May, producing a mass of bright colours which will fill your garden as summer turns to autumn. Our collection of decorative dahlias will give you large, double blooms with colour-splashed petals and each pack provides 5 mixed colour tubers, which will reach around a metre tall, and produce plenty of flowers each. These can be cut for the house, or left to enjoy outdoors. Dead-heading will prolong flowering well into autumn. Plants will survive milder winters, but we recommend lifting the tubers and storing somewhere dry and frost-free over winter, or left in pots if that's how you choose to grow them.
