One evening, a man was on his way home when he saw a woman come by, hauling a cart full of flowers. The smell of her flowers perfumed the air with sweetness so easily that it seemed to lift his spirits. He had never experienced such wonder from the flowers of his own garden. "How much must I pay for your wonderful flowers?" he asked. "Take what you wish for." "What return must I make for them?" he asked again. "Your gratitude is enough." She said. So he filled his arms with flowers and hurried joyfully home. His wife and children also liked the remarkable flowers, for they, too, discovered that the sight of them was a delight and the smell of them refreshed the soul.
In order not to lose his treasure. the man planted the flowers in his garden. Sunlight and water kept them amazingly beautiful and they still performed their powerful magic. When his children came to play in the yard, the man cautioned them against carelessness and wild play in case they damage the flowers. But the flowers remained hardy and strong as long as there are enough sun and moisture to nourish them.
