Previous tallest sunflower record
I've been trying to research previous sunflower records. I got my hands on the 1983 Guinness Book of World Records (hardcover). It listed the tallest sunflower as 23 ft. 6 1/2 in. grown by Frank Killand of Exeter, England in 1976. It shows a picture very similar to the picture that is on the Ripley's Believe It or Not - Giant Sunflower package. I wondered where they got that picture from on the package, and now I know where they got the picture from. Hopefully, the Ripley seeds are descendents of Frank Killand's sunflowers. I'm going to research this further.
