Dahlia variabilis Garden Dahlia

Dahlia variabilis, commonly known as the garden dahlia, is a vibrant and diverse species celebrated for its wide array of flower forms and colors. Originating from Mexico, this plant has been extensively hybridized, resulting in thousands of cultivars that showcase variations in bloom size, shape, and hue. Dahlias are known for their striking, often large flowers that can be single, semi-double, or fully double, making them a favorite among gardeners and florists alike. While they are perennials in USDA zones 8-10, in cooler climates, they are typically grown as annuals or lifted and stored over winter to protect their tuberous roots from frost. Dahlias thrive in full sun and well-drained, fertile soils, providing a spectacular display from midsummer until the first frost.
