Calendula

An Annual plant with large yellow or orange terminal flowers, calendula resembles the marigold and blooms from June through October. It prefers full sun and moderately fertile soil and readily self-seeds. Calendula is used externally for its antiseptic and healing properties, similar to comfrey. As a tea or tincture, it can be swished and swallowed to help heal an oral lesion, sore throat, or gastric ulcer.
