This is a favorite of mine that MeMa painted in 1976 a year or so before I was born. I always showed an interest in it and sure enough she made sure that it was known that it would go to me one day and now it proudly hangs in my living room.
Always a good idea to pinch or deadhead your annuals however when doing so, always remove the faded flower from the base of the plant so that you're not left with a stub that ends up turning brown and slumping over. Picture shows this maintenance flaw in detail.......
