It is a nice family project as everyone can pitch in with either ideas of what to plant or participate in the actual preparation of your indoor garden. Please, make sure the plants you choose are edible to avoid tummy aches or more serious illnesses. There are many detailed books including pictures on the market for you to investigate. Below is a partial list of edible plants to select from. For an unexpected treat, allow the plants to bloom - their flowers can be a delicious addition to a salad.
Some chives produce blue flowers that add a pretty blush with an oniony taste.
Just remember to harvest the flowers before they form seeds that are crunchy but have little flavor. You can use those tops and flowers in several ways. Try making a tangy sun tea by filling a clean glass jar with bottled water. Then toss in a couple of tea bags, and add a handful of Cinnamon or Anise Basil flowering tops. Cover the jar and place it in the sun for a few hours.
