Sweet Flag, also known as Acorus calamus, is a perennial plant that is known for its sweetly fragrant foliage and its tolerance for wet conditions.

This plant typically grows to a height of 2-3 feet with a similar spread. It prefers full sun to part shade and thrives best in wet, boggy soils, making it a great choice for water gardens, pond edges, or other areas of the landscape that stay consistently moist.

The leaves of Sweet Flag are sword-shaped, bright green, and have a sweet, spicy fragrance when crushed. In the summer, it produces inconspicuous, greenish-yellow flowers on a spadix, similar to many other water-loving plants.
