This depends on the variety and growing conditions. You should expect it to take between 60 and 90 days to bloom.
In a few days it will sprout. A
pproximately
3 months you will have a fully grown sunflower.
About 3 weeks
I think it should be about three months
40
it takes about 80 to 120 days (all summer) for a sunflower to grow.
It won't because the seed will be dead
it takes 2 days.
a few weeks
you spray perfume on it
the seed will likely germinate in 12 days
10 years
One. One seed per plant. However, some plants may grow more than one flower.
Its no for sure but it takes about 7-14 days to germinate. And maturity takes about 2-4 months. Make sure you take care of it closely very, very, closely.
probably a week or two
6 WEEKS
it takes up to a week for a the seed to germinate, then it can take up to a month for it to turn into an actual plant, then a few weeks from then for the sunflower head to start growing. so all up it takes a few months for the sunflower to actually grow and you won't get any seeds from it until it is fully grown. :)
