Black Jack Dahlia Tuber – Deep Crimson Cactus | Ships Spring 2027

Deep crimson petals unfurl into a dramatic starburst, their narrow, pointed shapes catching flashes of ruby light against near-black burgundy shadows. Black Jack brings sculptural texture to a summer border and a rich, velvety focal point to freshly gathered bouquets. Each order includes 1 dahlia tuber.

Pair its dark berry tones with soft blush and cream for contrast, or weave it among warm reds for a richly layered cutting garden. Despite its name, the flower is deep crimson and burgundy, not true black.

Planting & care

Plant after the danger of frost has passed and soil has warmed. Choose full sun and well-drained soil. Provide support as needed, avoid soggy conditions, and water regularly once growth is established. Remove spent flowers to encourage more blooms. In colder climates, lift tubers after frost and store in a cool, dry, frost-free place over winter.
