What is the Tallest Sunflower?

In 2014, Hans-Peter Schiffer grew the tallest sunflower ever recorded, measuring an astounding 30 feet and 1 inch tall.

Tall Sunflower Varieties

Gardeners worldwide adore giant sunflowers. The American and Russian Giant Sunflowers are particularly popular, reaching heights of up to 14 feet and boasting large seeds for snacking.
