‘Brigitta Alida’ Dahlia produces large, fully double dinnerplate flowers in a deep, velvety burgundy-red tone, almost black. Numerous narrow, slightly rolled florets give each flowerhead dynamic texture between decorative and semi-cactus form. Carried on sturdy stems above green foliage, blooms dominate a clump approximately 100 cm tall. They repeat from midsummer until the first frost and provide remarkable cutting performance. The Van Noort package contains one clump of tubers intended to create a dark focal point in sunny borders or spectacular bouquets with rich colour, strong visual weight, and enough petal movement to distinguish it from smoother dinnerplate cultivars.

Plant the tuber in spring after frost danger has passed and the soil has warmed. Set it horizontally about 10 cm deep with the crown and buds facing upward, then space plants approximately 50 cm apart. Reserve a warm, sheltered position in full sun with fertile, humus-rich soil that stays moist yet drains thoroughly. Water sparingly until shoots emerge, then water deeply when the surface begins to dry, without leaving water around the tubers. Incorporate mature compost, then apply potassium-rich fertilizer while buds develop. Pinch young shoots and install robust stakes early because the large flowers become heavy after rain. Tie stems loosely as they lengthen and avoid excess nitrogen that can weaken growth.

Place ‘Brigitta Alida’ toward the back of a border, in a cutting garden, or at the centre of a large bed. Dark burgundy-red tones combine with cream cosmos, white ammi, silver salvias, and bronze grasses. Harvest flowerheads when fully open and remove fading blooms promptly to stimulate replacement buds. A very large stable container can hold the plant when staking and watering remain rigorous. In cold Canadian climates, lift the tuber after the first frost, let its surface dry, and keep it somewhere cool, dry, dark, and frost-free. Inspect it monthly and replant only firm tissue once spring soil has warmed, preserving viable buds for another productive season.
