Pale yellow button flowers appear in late summer on spreading, 2 foot tall clumps. Will tolerate shade but produces more flowers in sun. Divide every few years.
Traditional Healing Uses: Costmary tea has been used to treat upset stomachs, dysentery, liver and gall bladder problems.
Other Uses: Costmary leaves were famously used as bookmarks for Bibles and prayer books. Drowsy worshippers sniffed or nibbled the fragrant balsamy leaves to revive themselves during long sermons. Young fresh leaves add a minty flavor to fruit, salad, iced tea, and punch, or can be added to soup, stew, or roasted meat for a more lemony taste. Use dried leaves in potpourri or sachets.
Harvest: Gather and dry a few leaves at a time throughout summer. Cut back flowers to encourage leafy growth.
Preparation: Pour boiling water on 1-2 teaspoons of dried herb and infuse for 10 minutes, twice a day.
Caution: Do not use during pregnancy.
