Addendum. Try f16 for a little better DofF.
Very nice composition but most of photo is out of focus because of the slow shutter speed. For most outdoor plants even in a very slight breeze, I find that I need at least 1/250s or faster. This subject is very hard for the meter to focus on correctly. I would use spot focus and preferably manual to get the center stem sharp. Don't be afraid to use a somewhat faster ISO with your camera. You can clean up any noise with post processing.
