Description
Dahlia Hartenaas is a delightful Collarette-type dahlia that brings cheerful charm and pollinator appeal to the summer garden. Its 3–4" blooms feature rosy pink petals edged in white, surrounding a golden yellow center with a neat inner collar. Compact at just 20–24" tall, this variety is perfect for borders, small gardens, or containers. Its open, daisy-like form makes it a magnet for bees and butterflies, adding life and movement to your beds. Plant tubers in spring after the last frost in full sun and well-drained soil, spacing them 12–15" apart. With blooms from midsummer to fall, Dahlia Hartenaas is an easy-care choice for both color and pollinator-friendly planting.
