- Sunflowers are a great choice for planting to attract birds to your yard.
- Sunflowers are one of the fastest growing plants. They can grow 8 to 12 feet tall in rich soil within six months.
- It require only 90 to 100 days from planting to maturity.
- The daily orientation of the flower to the sun is a direct result of differential growth of the stem. A plant-growth regulator, or auxin, accumulates on the shaded side of a plant when conditions of unequal light prevail. Because of this accumulation, the darker side grows faster than the sunlit side. Thus, the stem bends toward the sun.
- Sunflower seeds are rich in oil, which they store as a source of energy and food. Sunflower seeds are crushed to give us oil. We can use sunflower oil for cooking.
