Make a colourful addition to your garden with wilko Dahlia Cactus Mixed Spring Planting Tubers 5 Pack. 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. These Cactus Dahlias will give you large, double blooms with narrow, spiky petals. Each pack provides five mixed-colour tubers. They will reach around a metre in height and produce plenty of flowers. Dead-heading will prolong flowering well into autumn. Plants will survive milder winters, but it's recommended to lift the tubers and store them somewhere dry and frost-free over winter or leave them in pots if that's how you choose to grow them. Flowers grow to 50cm (Spread) x 100cm (Height).
