HUGE!!!!
If you want extremely large sunflowers get these!! Planted 3 packets with a 98% successful plants coming up! Planted this year and at the end of June they are 9’ and still growing and haven’t formed a complete seed head yet!! I’m sure those will be just as advertised!! Can’t wait to see them all in full bloom!
