Fame

The flowers you grow are more likely to be famous than you are. That excellent purplish hydrangea that Madonna loathes...someone grew that, and that someone could have been you. (If you don't know about it, do like Madonna suggests and look it up.)

Your flowers may be seen in the background at the Academy Awards, or at the presidential inauguration, or at the wedding of someone famous. Hey—they may even adorn the floats at the Rose Parade. You, however, won't get much credit for that.
