The decorative Dahlia ‘Wittem’ is a rewarding summer bloomer that bloom from July until the first night frost. The striking white flowers with brushes of lilac are perfect in sunny borders, gardens or containers. Dahlia bulbs are sensitive to frost, so don’t plant too early. The planting distance of the tubers is 30-60 cm and 3-5cm deep. Water the tubers immediately after planting. Store the tubers in a frost-free place after flowering and you will enjoy them for years to come.
