Grandalia™ Dark Red Dahlia

Grandalia™ Dark Red is a named Dahlia x hybrida selection with upright growth and red double flowers. Syngenta lists this code for part sun to full sun and spring-through-summer flowering; its Americas series profile gives a compact, uniform plant suited to larger containers, about 14–16 inches tall and 18–22 inches wide ([product profile](https://www.syngentaflowers.com/ams/product/flower/70052845), [2024–2026 series catalog](https://online.flippingbook.com/view/636494595/30/)). ## Seasonal interest The double blooms bring a strong red accent to patio pots, mixed annual displays, and sunny borders. The breeder identifies this selection as pollinator friendly. Its upright habit gives the flowers a clear vertical presence among lower-growing companions, and the listed flowering period extends from mid-spring through summer. ## Placement and growing Choose a sunny to partly sunny position. Dahlias grow best in fertile, well-drained soil; container plantings need drainage and regular attention to moisture, especially in warm weather. The listed dimensions are mature garden ranges rather than a single guaranteed point, so allow room for an 18–22-inch spread. ## Maintenance Remove faded flowers regularly to encourage continued flowering. Dahlias are tender where freezing weather occurs; protect the tubers from frost or lift and store them in a frost-free place, following local winter conditions ([RHS dahlia growing guide](https://www.rhs.org.uk/plants/dahlia/growing-guide)).
