Herbs are easy and useful in the kitchen. Thymes, Rosemary, maybe Lavender are pretty forgiving and easy to grow from seeds Oh and nasturtiums, super easy to grow, beautiful flowers which you can use in salads (the are a bit spicy like cress) and they give you tons of new seeds at the end of the season, which you can plant the following year. Other than that just have fun and try stuff.
He’s not your friend, pal.
