Native plants play a special role for pollinators in providing habitat for their own life cycle. We are all familiar with the necessity of having milkweed available to support the life cycle of the Monarch Butterfly. Without these and other pollinators, no life can survive on Earth. Of the 1,400 crop plants grown around the world, about 80% require pollination by animals. Visits from bees and other pollinators are vital to crop health. In the United States alone, pollination of agricultural crops is valued at 10 billion dollars annually.
