The dahlia with probably the largest flowers. As big and big as her flowers are, her color is so delicate and delicate. When opened, there is a soft pink shade that changes to a creamy coffee color as the flowers mature. To fully enjoy this Dahlia, it is best to place it in the warmest and sunniest spot in the garden. Café au Lait is a late-blooming Dahlia that needs time and warmth to blossom, but it is well worth the wait.
