National Plant Network's grower approved selections take the guesswork out of gardening. This premier dahlia collection features a stunning array of flower forms including massive dinnerplate blooms, perfectly symmetrical globes, and unique collared petals in a vibrant rainbow of colors. By planting this diverse mix, you create a high impact landscape with varying heights and textures that provide a steady supply of professional quality cut flowers from mid summer until the first frost. Dahlia tubers arrive in a dormant state and appear as starchy root clumps that are ready to burst into life once the spring soil remains consistently warm. These tubers are easy to plant, just soak them in lukewarm water for several hours before placing them about four to six inches deep with the growing eye facing upward in well prepared soil that receives plenty of sunlight. After planting, new growth typically begins within a few weeks as temperatures warm, followed by dense green foliage and a spectacular succession of colorful flowers. These tubers offer an economical way to enjoy prolific blooms year after year and can be successfully overwintered in colder zones by digging them up and storing them in a cool, dark, frost free location once the foliage has died back.
