Smokey Amethyst Dahlia Mix (Dahlia pinnata ‘Smokey Amethyst’) brings together beautiful decorative dahlias with large, fully double flowers in a sophisticated palette of violet, lavender, and creamy white. Their perfectly formed petals evoke the subtle tones of amethyst and stand out elegantly against dark green foliage. From July to October, abundant blooms are produced on compact plants reaching approximately 70 cm (28 in) tall. This fast-growing selection adds depth and refinement to summer landscapes. A tender Zone 10 perennial, it is not hardy in Quebec and must be overwintered in a frost-free location.

Plant the tubers in spring after all danger of frost has passed, 10 to 15 cm (4 to 6 in) deep in rich, fertile, organic, and well-drained soil. Choose a location in full sun and space plants approximately 50 cm (20 in) apart to promote good air circulation. Water lightly after planting, then more regularly as growth accelerates, keeping the soil evenly moist without becoming waterlogged. Fertilize every two weeks while avoiding excessive nitrogen, remove spent flowers regularly, and stake the stems if needed. Lift the tubers before the first frost and store them in a cool, dry location.

The ‘Smokey Amethyst’ mix is perfectly suited to sunny flower beds, flowering borders, large containers at least 45 cm (18 in) in diameter, and cutting gardens. Its rich colours pair beautifully with cosmos, salvias, verbenas, zinnias, and ornamental grasses to create refined, balanced displays. The large double flowers have excellent vase life and are ideal for creating elegant bouquets that remain attractive for several days. Their abundant blooms also bring life to the garden and may attract a variety of pollinators. Frequent harvesting and regular deadheading extend flower production until the first frost.
