This is a Cactus Dahlia mix. Native to Mexico and Central America, Dahlias are tuberous rooted perennials in the Aster family. A popular variety with florists and flower arrangers which gives good quantities of large double and semi-double flowers with distinctive spiky petals. They grow to a height of 60 inches, 1.5 meter and spread over 40 inches, 1 meter. Flowers from less than 4 inches to more than 10 inches across. Petals are pointed and tubular. These bold flowered Dahlias produce large, spiky cactus blooms in a range of attractive colours. It flowers from July to September. Remove deadheads to prolong flowering season. Hardiness zones 7-10, (-15°C/5°F, 1°C/35°F) in Winter. In all but the hottest climates, grow Dahlias in full sun. In hot Summer areas, do best with some afternoon shade. Dahlias prefer moist, but well-drained soil. If you have sandy soil, add compost or other organic material to increase water retention. For heavy clay soil, add sand and organic material to increase drainage. The plants should be watered regularly during dry spells. Tubers are frost tender, but can be re-used each year if they are lifted in the autumn and stored in the fridge. Dahlia shoots are frost-sensitive; plant tubers in the garden no sooner than two weeks before the last date of Spring frost. In the South, plant tubers from April 15th to May 1st. Or, to avoid the intense heat of midsummer, plant in June so that flowers develop in the Fall.
