Dahlia pinnata
Black Forest Ruby

Smoldering with rich color and irresistible contrast, Dahlia pinnata ‘Black Forest Ruby’ combines deep bronzy-black foliage with vivid ruby-red blooms that practically glow against the dark leaves. The semi-double flowers dance atop branching stems from midsummer until frost, drawing in bees, butterflies, and endless admiration from garden visitors. Compact yet wonderfully floriferous, this dramatic dahlia brings a lush, almost tropical richness to borders, containers, and cutting gardens.

Growing about 2–3' tall, ‘Black Forest Ruby’ thrives in full sun with fertile, well-drained soil and regular summer watering. Pinching young plants encourages bushier growth and even more blooms throughout the season. We especially love the sultry combination of dark foliage with jewel-toned flowers, making it easy to pair with lime greens, smoky purples, and soft peach companions. Excellent in bouquets and remarkably long blooming, this beauty delivers nonstop color and theatrical flair right up until chilly autumn nights arrive.
