Dahlia Thomas Edison

Dahlia Thomas Edison is a stunning decorative variety prized for its rich, deep burgundy blooms with velvety petals that deepen to near-black in strong sunlight. This vigorous grower produces abundant 4–5 inch flowers from mid-summer through fall frost, making it a showstopper in borders, cutting gardens, and containers. Plant in full sun with well-draining soil and space 18–24 inches apart.
