OMG- I just Love this Sunflower. She (or maybe its a He!) grows massively tall - she/he or it! was reaching the top of our poles in the tunnel house.. and more! Just like a Triffid! We grew this variety of sunflower from untreated seeds. She produces pollen, unlike the other commercially grown sunflowers with the dark disk in the center which have been chemically treated and can harm or kill insects and bees who land on the flower, but not with our ladies! We had heaps of bumble bees!
