Dahlia 'Jack Frost'
Jack Frost Dahlia
Dahlia 'Jack Frost' features crisp white blooms held in a semi‑cactus form, with sharply pointed petals that twist back subtly, revealing a bright yellow center that adds warmth to each flower. The crisp heads begin appearing in midsummer and continue steadily into early autumn, providing a clean and reliable display on upright stems. The pure white tone maintains its clarity as the blossoms mature, making them excellent for garden panels and cutting gardens alike. With strong stem support and a steady bloom cycle, 'Jack Frost' delivers long‑season presence with refined simplicity.
