Venti™ Red+White Dahlia

Venti™ Red+White is a mounded dahlia with double red-and-white blooms for bright summer borders and large containers. Ball Seed identifies the cultivar as ‘DATRETTEN’ and reports a mature height of 16–18 inches and width of 14–16 inches, with flowers from spring through autumn. ## Garden use Use this compact plant near the front or middle of a sunny bed, or as a colorful feature in a roomy container. Its contrasting red and white flowers suit mixed annual plantings and provide a clear focal point. Ball Seed notes that this Venti selection attracts bees and butterflies. ## Growing conditions Give it sun or partial sun in fertile, well-drained soil. The Venti listing describes medium water needs; water during hot, dry spells so the root zone does not dry for long periods. Dahlias flower best in a warm, bright position. ## Maintenance Remove spent flowers regularly to encourage more blooms. In cold-winter regions, cut back after frost and lift the tubers for dry, frost-free storage, then replant after danger of frost has passed.
