Masamune Acorus. This selection is a dwarf variegated cultivar of the more familiar Sweet Flag which will max out at about 6" tall. Its leaves are streaked white and green just like the familiar and larger Acorus garmineus 'Variegatus.' As with all Acorus, they seem to be most content in shade to full sun with uniform moisture. They will even grow in very shallow standing water and work well into water gardens.
