Let's be a little kinder to ourselves and say instead of lazy, who has the time to garden!  I first discovered a "no-brainer" flower to grow when a friend of my daughter's asked me to recommend a flower he could plant in front of his fraternity house before he left for the summer. Well, that was a tall order: Plant and run! So I gave him some Cleome and crossed my fingers. I actually worried about them because it was a terrible summer with hardly any rain.
