For tall sunflowers, be sure to plant the seeds in an area where the leaves of the growing sunflower plant will be in full sun. This means that the plant should receive a minimum of 6-8 hours of direct sunlight each day. Sunlight is required for photosynthesis, which is how the plant is able to grow so tall. Don’t try to grow giant sunflowers in the shade! Mammoth sunflowers will generally take the entire summer to grow from seed to bloom. However this does not mean that the plant growth is slow.
