Awesome
These are great seeds. I started them indoors this spring and they are now outside. I transplanted them in the front of my house and all the neighbors stop and compliment them! I have never been disappointed with my Rohrer Seeds! Especially the. Mammoth Russian Sunflowers, which live up to their name for sure.
