‘Dahlegria Tricolore’ Mignon dahlia (Dahlia ‘Dahlegria Tricolore’) Dahlegria Tricolore dahlia is a single-flowered Mignon selection registered as ‘Dahlgr85’. Its 7 to 10 cm flowerheads carry broad pink petals shaded peach, marked red at the base around a brown disc that opens dark yellow. This changing palette stands out against dark green leaves flushed purple and similarly purple stems. The upright clump grows approximately 60 cm tall and 50 cm wide. It flowers from midsummer until the first frosts. Van Noort supplies one No1 tuber suited to containers, sunny borders, and gardens visited by pollinators, where every open centre remains clearly accessible through the flowering season.
Plant the tuber in spring after the final frost once soil has warmed. Lay it horizontally 10 cm deep with the bud facing upward, keeping 50 cm between plants. Choose full sun and fertile, humus-rich soil that stays moist yet drains perfectly. Water sparingly before shoots emerge, then deeply at the base whenever the surface begins to dry. Incorporate mature compost and later use fertilizer moderate in nitrogen and richer in potassium when buds appear. Pinch young shoots to branch the clump. Remove faded flowerheads regularly to extend flowering, maintain a tidy plant, and keep fresh open discs available to visiting insects.
Place Dahlegria Tricolore near the front or middle of a border, in a large stable container, or among nectar-rich plants. Its pink, peach, red, and yellow tones pair with white sweet alyssum, blue salvias, purple verbenas, and golden grasses. Single flowers expose pollen and nectar directly to bees, butterflies, and hoverflies. Cut a few nearly open stems for arrangements without removing every garden resource. In Quebec, wait until the first frost blackens foliage, cut stems back, lift the tuber carefully, and allow its surface to dry. Store it labelled somewhere cool, dark, dry, and frost-free until spring, checking occasionally and retaining only firm healthy tissue.
