Dahlias come in a wide variety of shapes, sizes, and colors. The blooms can range from small, delicate flowers to large, showy blossoms measuring up to 12 inches (30 cm) in diameter. They can be single, semi-double, or fully double, and their petals can be round, pointed, or twisted. The colors vary greatly and include shades of white, yellow, orange, red, pink, purple, and even bi-color combinations.Dahlia plants are herbaceous perennials, meaning they die back to the ground during winter and regrow in the spring. They have green, fern-like leaves that are typically divided into several lobes. The plants can reach varying heights, ranging from a few inches for dwarf varieties to several feet for taller cultivars. Some dahlias have a bushy growth habit, while others may require staking to support their tall stems.
