The large-flowered, dinner plate Dahlia, ‘Grand Prix’, is an easily grown summer bloomer that flowers from July until the first frost. The huge yellow, white-tipped petals make this flower 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.
