What is the growth rate of sunflowers?

Answer 1

My Little Giant seeds have all been volunteers for the past have dozen years. They sprout in late April or early May, and reach their full height by early August. They continue to mature until the end of August and into September, but their full height is achieved within 90 days.

They average about 10 feet, though the head bends the stalk down. If they were straight, and the root ball was included, you would have about 12 feet altogether, or 1.6 inches per day. I should try measuring them this year, in the morning and in the evening--12 hours apart, to see what part of the day the biggest spurt occurs.
