Dahlias
Dahlia '20th Ave Tranquility'
20th Ave Tranquility Dahlia
Dahlia '20th Ave Tranquility' features soft lavender blooms held in the formal decorative form, defined by tightly layered petals arranged in concentric rings that form a smooth, rounded flower face. Flowering begins in midsummer and continues through to the first frosts of autumn, offering weeks of subtle color and refined structure.
The consistent lavender hue invites a sense of grace, while the miniature‑sized heads perched on long stems provide versatility for both garden borders and floral arrangements.

Planting & care
Growing beautiful dahlias starts with thoughtful planting and care. A sunny location, well-draining soil, and consistent attention throughout the growing season help plants develop abundant flowers. Regular watering and feeding encourage healthy growth, while mulch helps conserve moisture. Removing spent flowers keeps plants blooming freely from summer into fall.
