Karma Amanda Violet White Bicolor Dahlia

Karma Amanda Violet White Bicolor Dahlia (70089127) is an upright, vigorous Dahlia x hybrida bred for cut flowers. Syngenta lists a 3–4 foot garden height, 18–24 inch width, full sun, flowering from late spring through fall, and hardiness zones 9a–11a ([Karma Amanda](https://www.syngentaflowers.com/ams/product/flower/70089127)). Its violet-and-white bicolor identity remains distinct within the Karma series. ## Growing Conditions Plant in fertile, moist but well-drained soil in full sun. Keep the root zone watered during active growth and mulch through hot, dry weather. Karma selections are cultivated for long, strong cut stems; cutting at a tighter bud stage helps extend vase life ([Syngenta Karma sell sheet](https://www.syngentaflowers.com/ams/sites/g/files/kgtney2381/files/media/document/2026/01/20/karma_dahlia_sell_sheet.pdf)). ## Maintenance Deadhead spent flowers to encourage continued bloom. Lift and store tubers in cold-winter areas or mulch them over in milder climates. For cut flowers, harvest before blooms fully open to support a longer vase life.
