Sunflowers can be between 3 and 18 feet tall, with the typical height of about 10 feet. There are about 60 kinds of sunflowers, thus accounting for the wide range of heights. They’re a heliotropist plant, meaning they turn to face the sun as it moves throughout the day.
The tallest sunflower on record measured 25 ft. 5 ½ in. (7.76m). It was grown by M. Heijms in Oirschot, Netherlands in 1986.
Sunflowers can grow to be truly enormous, much taller than a person. In Kansas, my home state, they grow naturally in many places, in great, tall fields. Unfortunately, and ridiculously, some people consider them “weeds,” and cut these glorious fields for the sake of parking lots and gas stations. In any case, these are of great use for permaculture, as they are not particularly difficult to grow, and they are great natural shields for other plants.
