    My 1st bulb purchase and these did not fail. Put in a pot and it gave me over 10 flowers. I did not plant till June. I had flowers till Oct.

    Customer photo review of Dahlia Tubers (Dinnerplate) - Mystery Day

    I ordered two variations of tubers, the Vintage Violet Mix & this one and it looks like I was sent the wrong tubers. My first one just bloomed and it’s orange. Was very disappointed that it was not the coloration I expected.

    These did not disappoint. I was actually surprised when the first bloom opened this summer, as it was so beautiful and lovely. I cut them and loved having fresh flowers all summer long! We finally had our first freezing cold snap & I am sad to see them go. Can’t wait to enjoy them again next year! They will need to find a new spot, or I need to find another way to support them.. they grew so tall. Absolutely stunning! My parents enjoyed many bouquets!

    1st year planted, tubers bloomed without hesitation. Required no special conditions or treatment in our garden. Dark purple color, nice contrast to white. Bloomed all summer till frost (Upstate S.Carolina)
