About this plant

Dahlia 'Allen's Showcase' produces elegant, small blooms in a semi-cactus form with pointed, slightly twisted petals. Each blossom opens with a luminous white base that gradually transitions to fuchsia-raspberry at the tips, giving the blooms a bright two-toned effect. The vivid color near the ends of the petals appears brushed or stained onto the white, creating a soft yet dramatic contrast across the flower head.

Blooming steadily from midsummer into fall, this variety adds seasonal interest and texture with its narrow, spiky petal form. The intense coloration and layered appearance enhance the dahlia's presence in both gardens and cut arrangements. Its compact blossoms are especially effective when grouped together, where the contrasting white and raspberry tones create a lively, dimensional display.

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.
