Blue Bell Dahlia Tuber

The Enigmatic Blue-Purple Beauty

Dahlia 'Blue Bell' is celebrated as one of the most stunning "blue" dahlias, displaying a rich canvas of violet-purple blooms that gracefully mature into soft, sought-after lavender-blue at the tips of the petals. This mesmerizing color transition makes it a standout in the garden and a highly desirable flower for professional florists.  

As an Informal Decorative type, its fully double blooms are comprised of broad, slightly wavy petals that create a soft, flowing texture. This dahlia is a prolific bloomer, producing numerous 4-6 inch flowers on sturdy, upright stems from mid-summer until the first frost. Plant 'Blue Bell' to create instant focal points in borders, or pair it with pinks and oranges for a truly captivating contrast.
