I must go around with my eyes shut on our daily perambulations. Yesterday was the first time I had noticed a Sunflower growing next to the cricket field. It's not as though it is a miniature. Far from it.
It is probably the tallest I have actually seen with my own eyes:
I usually grow a few myself though they never grow to that sort of height.
Last Spring I forgot all about stealing a few seeds from the birds' supply.
