Customer Reviews

amazing growth

Planted a row of these seeds in a newly-tilled garden at the end of March (coastal California). They sprouted quickly, and now, two months later, range from six feet to eight feet tall! That's about a foot a week growth for the tallest ones. The first few are just starting to form buds. Considering that I have never been able to grow sunflowers previously, these are wonderful.
