Safety Overview
1.Dahlia Dinner Plate — Introduction & Highlights
Dahlia × hortensis, commonly known as the Dinner Plate Dahlia, is a magnificent hybrid within the Asteraceae family, celebrated for its exceptionally large and showy blooms. This tuberous perennial typically grows to an impressive height of 3 to 4 feet (0.9-1.2 meters), producing sturdy, hollow stems that often require staking to support the weight of its voluminous flowers.
The leaves are characteristically pinnately compound, presenting a lush, dark green backdrop that beautifully contrasts with the vibrant floral display. Native to the mountainous regions of Mexico and Central America, the ancestral species of Dahlia thrive in temperate climates, and this hybrid cultivar flourishes under similar conditions.
The defining feature of the Dinner Plate Dahlia is its capitulum inflorescence, which can reach an astonishing 12 inches (30 cm) in diameter, resembling a dinner plate. These flower heads are composed of numerous ray florets, often densely packed, exhibiting an extraordinary spectrum of colors including pristine whites, delicate pinks, fiery reds, cheerful yellows, and warm oranges, often in solid, bi-color, or variegated patterns.
The plant's root system consists of fleshy tubers, crucial for its perennial nature and serving as storage organs that allow it to survive dormant periods. Dahlia × hortensis is primarily cultivated for its ornamental value, adding significant aesthetic appeal to gardens from summer through fall, and is also a notable attractor of pollinators such as bees and butterflies, contributing to garden biodiversity.
