Black Jack is a dramatic semi-cactus dahlia prized for its deep, velvety dark red blooms. The 6-8 inch flowers feature elongated, slightly twisted petals that create a bold, spiky silhouette with striking texture and depth.

Its rich, saturated colouring reads almost burgundy-black in certain light, making it a powerful accent flower in both moody and high-contrast palettes. Black Jack pairs beautifully with blush tones, soft apricot, creamy whites, muted mauves, and autumn arrangements.

Plants grow to approximately 3.5-4 feet tall and produce strong stems suitable for cutting. A reliable performer, Black Jack adds structure and intensity to cutting gardens and bouquet production.
