Chives grow in clusters, their blade-like leaves growing straight upward. The green leaves are hollow, and come to a point. Chives can grow up to two feet tall in ideal conditions, and can spread out up to 12 inches around. They have a mild onion flavour, that doesn?t tend to leave a long aftertaste. Chives sport globular spiky, pinkish-purple flowers in the early summer months, which are also edible and share the same mild onion taste. Some varieties of Chives have white and red flowers.
