Plants make energy from sunlight through photosynthesis, and can thrive only if they receive the right amount for their needs. Different plants have evolved to survive in different conditions; some love shade, while others prefer their heads in the sun. Plants also offer clues about the conditions they enjoy — those with small hairy or gray leaves, such as lavender, enjoy sunny sites, and those with large, dark green leaves grow well in shade. When choosing plants, check their light requirements and plant them in an appropriate place. Young plants are particularly vulnerable to poor light conditions and will struggle to get established if the sun is blocked by weeds, so keep the area around them free of competing plants as they mature.
Sunflowers literally love their heads in the sun and the blooms follow its path throughout the day.
