Velvet-dark petals, wine-red highlights, and a silhouette that refuses to disappear into the border. ‘Black Jack’ is a striking semi-cactus dahlia whose long, pointed petals curl slightly inward, creating lush, sculptural blooms. Its deep burgundy-red flowers can appear almost black in certain light, a beautiful contrast beside softer garden colors.
