Dahlias
Dahlia 'AC MP'
AC MP Dahlia
Dahlia 'AC MP' produces vivid magenta-purple blossoms with long, narrow petals that curve and twist outward, creating the dramatic, spiky appearance characteristic of cactus dahlias. Measuring 4 to 6 inches across, the flowers combine saturated color with a dynamic, sculptural form that adds texture and movement to the garden.
Reaching 4 to 5 feet tall, 'AC MP' brings strong vertical presence to garden beds and works especially well toward the back of borders.

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.
