Dahlia in black! Wonderful dark burgundy, almost black, semi-cactus blooms give Dahlia Trebbiano and hint of sophistication. Grow in full sun to bring out the deepest colour - the blooms will start out very dark becoming deep red as they age.
Plant in any soil enriched with plenty of compost. Like all Dahlia, it is not fully winter hardy and will need to be protected over winter. See our Plant care section for more details.
