The plants are: 1) eggplant, 2) tomato, 3) spearmint. You can learn this and much more by planting a garden and by visiting plant nurseries.
Gardening can teach us about the natural rhythms of life. A well-tended garden can provide us with greenery, flowers, and fruits. If we do not pay attention to the needs of our plants, they will wither and die or become infested with plagues. A beautiful garden is a testament to our awareness of nature.
