Acorus calamus ‘Variegatus’
Natural sweet flag is believed to originate from India. It is now found through much of Europe and Asia, as well as North America. This cultivar has green and white leaves instead of green leaves, and is not found in the wild. The name sweet flag is probably due to an old practice of simmering the roots to prepare a candy; it may also be because the foliage and root stalks have a pleasant aromatic fragrance. The American poet Walt Whitman was enamored with sweet flag, devoting 39 poems to it.
Identification: This cultivar reaches 2-3′ (60-91 cm) in height, with many long, grasslike leaves ¼-⅝″ (7-17 mm) wide. In this species, the leaves have a prominent middle vein, somewhat raised secondary veins, and multiple very small tertiary veins. This cultivar has creamy white stripes along the leaves. An inconspicuous greenish flower called a spadix, looking a little like a miniature corn on the cob, is 1¾-3½″ (5-9 cm) long. It grows in shallow water or extremely wet soil.
