Description

Dahlia pinnata 'Dandy Improved Mix' is a delightful, open-pollinated heirloom dwarf collarette selection prized for its unique multi-tiered petal structure and compact garden habit. Growing into bushy, upright plants that reach 16 to 24 inches in height, it produces charming 3- to 4-inch semi-double flowers. Each bloom features an outer ring of broad ray petals accented by an inner "collar" of shorter, contrasting petaloids surrounding a golden central disc. The brilliant color palette includes shades of crimson, pink, bronze, yellow, orange, and white, often paired with crisp white or pale yellow collars. Extremely fast-growing and easy to start from seed, Dandy Improved Mix blooms continuously from midsummer until frost, making it a standout choice for borders, patio containers, and petite cut bouquets.
