Mammoth GreyStripe Seeds

I'm very pleased with my recent purchase of Mammoth Greystripe Sunflower Seeds. Customer service was great when I had to make a change on my order and the seeds arrived in a timely manner. The seeds themselves look beautiful and healthy and I'm very excited about getting them in the ground soon.
