Sandia Bertha is a bold, velvety waterlily‑form dahlia whose 6–7 inch blooms open in deep burgundy that surges toward electric magenta‑purple in bright light. Its saturated, moody palette mirrors the high‑contrast purples of ocean‑phase Chinook in deep water, where dark, wine‑toned shadows meet vivid magenta highlights along the flanks. Tall plants reach 4–5 feet and carry glossy, dark green foliage that intensifies the bloom’s dramatic color. Introduced in 2023 by Steve and Sandy Boley of Birch Bay Dahlias, Sandia Bertha is prolific, architectural, and unforgettable — a true statement flower for gardeners and designers who love rich, luminous color.
