I'm sorry i can't give you an answer but I have the same question too. :(
Just one Season.
A sunflower plant can regrow if it's cut in half because the remaining part contains dormant buds that can activate and grow new shoots. As long as the roots are intact, the plant has the ability to regenerate itself and continue growing.
The sunflower grows within a week as long as you water it twice a day.
If the sunflowers are not a hybrid variety, then you can save the seed by cutting the flowers when the seeds are fully formed and loose in the head, drying the whole head for two or so weeks, rubbing them from the head, drying for a further couple of weeks, and replanting in the spring. you can use hybrid varieties as long as long as they are not sterile in which case you wont get any seeds anyway. you just wont get the same flower vigor and or good looks. zaf.
15 feetCertain varieties of sunflowers grow 15 feet tall, but there are varieties that grow much shorter.
