One of the easiest herbs to grow, chives is apt to self-seed all over your garden. Also, this onion relative is a perennial, so you won’t have to plant it year after year, and can easily share seedlings with others. Chives will grow in almost any type of soil, provided they have plenty of sun and are not troubled by pests or disease. To harvest, use a pair of flower snips to cut off the stems close to the base of the plant. You can also use the purple or white flowers in salads or as an edible garnish for an entrée. Once the flowers are spent, deadhead them so they don’t go to seed and make more plants.
