I have planted gardens through art installations throughout the world, in countries of the people that I meet. Now they are lining parks and courtyards, painted on walls and even in blighted lots off the street. If you were in Berlin, Germany, you would have seen my garden at Stilwerk Design Center, where rosemary and lavender, hydrangea and lemon balm trailed up the glass elevators to all six floors. In 2009, I planted “Philosophers Garden”, a garden mural, blooming at the historic Frederick Douglass High School in
    Memphis, Tennessee. This school’s garden fed an entire community and was honored by Eleanor Roosevelt during the Great Depression. Again, in 2011, I planted at Court Square Park—six entry gardens with 80 varieties of deliciously fragrant floribunda and hybrid tea roses.
    Gardening has taught me that planting and growing a garden is the same process as creating our lives. This process of creation begins in the spring, when you break up the soil and start anew. Then it’s time to clear out the dead leaves, debris and roots of the winter. The gardener must then make sure that a good disposition and the proper nutrients are correctly mixed in the soil. Then it’s important to leave the topsoil loosely packed on the surface. You won’t get those beautiful blooms in life until you first do the work just right. When our gardens are balanced with care, we can harvest the beauty of living a life of grace.
     In the forests, when trees realize through their roots that another tree is sick, they will send a portion of their nutrients to that tree to help them to heal. They never think about what will happen to them or feel vulnerable when they do. When a tree is dying, it releases all of its nutrients to other trees that need it the most. Below the surface, we are all connected by our roots and sharing nutrients with each other. It’s only when we come together that we can honestly grow. It’s the same for humans in the garden of hardship. In this garden, when the caterpillar transforms into a chrysalis, this involves some struggle. But it’s a challenge with a purpose. Without this painful fight to break free from the confines of the cocoon, the newly formed butterfly can’t strengthen its wings. Without the battle, the butterfly dies without ever taking flight.
