The seeds are there. All they need is space and an opportunity to grow. If you have a yard or garden, dedicate a part of it to the wild plants. Scatter seeds of wild plants you would like to see grow there and then sit back and see what happens. Let nature take its course. Watch for the seedlings and then learn to distinguish one from another. Cultivate those that have food and nutritional value and remove those that don't. Growing wild plants is connecting with nature.
