4. Bok Choy
Bok choy grows back fast, making it perfect for beginner gardeners. Just cut off the leafy tops and keep the bottom two inches. Place the base in a shallow dish of water and set it in sunlight. Within days, new leaves will sprout from the center. Once roots form, you can plant it in soil to keep the growth going. Fresh bok choy is great for stir-fries, soups, and salads—plus it looks beautiful while growing.
