When I was a little girl we used to grow giant sunflowers along the back of the garden and I just loved the way they towered over me.

I have no idea. They were bright yellow petals and deep black large seeds, growing over 6 feet tall.

I do not know which species you are talking about but most species are native to North America.

I always wondered where the sunflower seeds for snacks are primarily grown.

They can be grown anywhere but  sunflower seeds are usually classified by the pattern on their husks

They have a unique way of growth and  referred to as oilseed sunflower crops.
