    Customer photo review of Dahlia Tubers (Decorative) - Blue Bell

    I received my Dahlias from a late Spring sale and didn’t get them until June and TN was already warming up! I was concerned they wouldn’t have enough time to mature and bloom. 3 of the 4 rhizomes grew. I started seeing some buds late August and now it’s blooming!!

    Customer photo review of Dahlia Tubers (Decorative) - Blue Bell

    Eden Brothers did an excellent job this year. All of the tubers they sent were perfect and just as described. My Blue Bell was one of the first to blossom (late in CT due to a cold spring and hot July). I bring them to coworkers to spread the joy and this one was noticed and admired. Last year’s reviews gave me pause with Eden but if there were any issues with dahlias then, they definitely addressed them and I’m very happy with everything I purchased. Thank you!!!

    This dahlia blooms true to its description! The deepest purple blooms with a yellow center. Bumble bees love them! The stems are strong and sturdy and hold their flowers upright. Perfect size for cut flowers arrangements, and bloom more when they are cut! Amazing!

    My Dahlia plant is growing quite large. It has five blooms ready to open any day. So far, it is a gorgeous plant.

    This is my first time ever growing dahlias and I am over the top. I was certain I would be the death of them but my bed is full of gorgeous flowers

    This is a favorite of mine. I have had it for 2 years. It produces a lot of blooms that are perfect for arranging. The purple color goes well with pinks, apricots and yellows. It is very versatile. It produces many tubers. One my second year I had 3 plants from 1 original tuber. I kept 2 and shared the other.
