Acorus gramineus 'Minimus Aureus'

Dwarf Golden Sweet Flag is a wonderful plant for walkways as well as rain gardens and stream edges, because it is tolerant of foot traffic as well as significant moisture. The evergreen foliage is like tiny thick bladed grass tufts and when crushed, it releases an attractive sweet scent. The tufts slowly expand to make a short yellowish green mat. Although it looks like a grass, Acorus gramineus 'Minimus Aureus' is actually more closely related to the Iris family.
