Bell pepper fruits are grown in a rainbow of fascinating colors: green, white, yellow, red, orange, and chocolate brown. Green fruits are actually immature peppers. If you leave them on the plant, they eventually will develop one of the other colors, most commonly red, and become sweeter. Bell peppers are being hailed as a superfood, low in calories, high in flavor, and vitamins A, C, and other nutrients. Bell peppers need temperatures above 16°C to grow well. It's best to protect plants from cold temperatures.
