About this plant
Dahlia 'Cooper Blaine' produces glowing red‑orange blooms held in the informal decorative form, which features loose layering of petals that unfold into a full, rounded silhouette with edge movement. Each flower begins in midsummer and continues through to early autumn, providing sustained color on strong stems. The rich red‑orange hue of the petals deepens toward the core, creating a warm visual glow that lights up garden beds and cut‑flower arrangements alike. With its buoyant tone and consistent bloom production, 'Cooper Blaine' brings energetic warmth and long‑season presence to late‑summer landscapes.
