American Giant Hybrid Sunflower produces massive stalks and blooms for the largest sunflowers you’ve ever seen! Great for creating borders and hedges. Plants grow 14′ tall on average with heads that are 1′ in diameter. Helianthus.
We put our giant sunflowers to work in our garden. Using them to trellis cucumbers during spring and summer and again in autumn to trellis late season peas.
