Easy to grow anywhere
They grew all over in every area I planted them, either as seeds or as transplants. They do get VERY tall, there is one with over 2" trunk growing in a sunny moist area of my yard and it must be at least 15' and isnt sloping over yet like my others did. Bees love these things, they were swarmed with them. I have a few that had smaller, very beautiful flowers that I cut and used in a vase and it smelled really good like sweet honey.

Excellent Yield!
I grow sunflowers every year, and these are my favorite so far. Sadly, I wasn't able to salvage the seeds because... Well... We ate them all. But I will be ordering more - and sharing with my best friend who is a Kindergarden teacher, so that she can grow some with her class.
