A show stopper in any setting, Dahlia ‘Black Jack’ is a dramatic and eye-catching variety prized for its bold, velvety blooms in a rich, dark maroon, so deep it is nearly black. The fully double, cactus-style flowers feature finely pointed petals that give the bloom a spiky, starburst appearance, adding striking texture and contrast to any garden display or floral arrangement. Reaching up to around 1.4m tall, this dahlia stands proudly in borders, containers, or the cutting garden, with strong stems that support its large, spiky blooms from midsummer right through to the first frosts. Its moody, gothic colour makes a stunning contrast against lighter flowers or silvery foliage, bringing a sense of sophistication and drama to your planting scheme. Dahlia ‘Black Jack’ thrives in full sun and rich, well-drained soil. Regular deadheading encourages a steady supply of blooms, making it a favourite among florists and gardeners alike. If you're looking to add depth, flair, and a touch of the unexpected, this dark beauty won’t disappoint.
