Dahlia ‘Mystery Day’ is an easily grown summer bloomer that flowers from July until the first frost. This large, double dinnerplate with dark red, almost burgundy, flowers tipped in white are beautiful to sow together or to integrate with other perennials or dahlias in sunny borders, gardens or containers. Sown in sunny areas, dahlia usually produce a large number of flowers. 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.
