Varigated Sweet Flag - Rain Garden Plant

Stunning Display at Missouri Botanical Garden 

Variegated Sweet Flag (Acorus calamus 'Variegatus') is a striking, wetland plant that grows from 2' - 4' tall. Each iris-like leaf sports a prominent creamy-white stripe. Zones: 4-8.

 It makes a punchy addition to a wet area; streamside, pond's edge, or in a container.

Creeping rhizomes slowly spread to form large colonies in favorable conditions, but the variegated form is not as aggressive as the regular green variety. 

ALERT: the normal green variety is now listed as an invasive -  The New Jersey Invasive Species Strike Team, http://www.njisst.org/index.asp, has this listed on the 2017 Do Not Plant List

This perennial doesn't require a bog or wetlands but it needs to be constantly wet in the summer months. Although native to Europe, it was introduced into North America by settlers in the 1600s, and has naturalized over time throughout much of the U.S.   Sweet Flag is hardy (Zones 4 - 10 ) and semi-evergreen in zone 7 and south.
