Plant Information
Culture: Acorus species are tough and easily grown. Because Acorus are native to pond margins, they prefer fertile, acidic soil that is constantly moist. Acorus resent drying out and will produce brown tips and burnt foliage. They tolerate sun to part shade conditions.
Maintenance: Acorus do not require much maintenance, however, they will benefit from division every few years when the center of the clumps become sparse. At this point, divide the rhizomes and replant them. Otherwise, maintenance includes cutting out dead or bad-looking foliage and keeping the plant moist.
Acorus gramineus is a great addition to mixed containers for sun or shade. It adds a wonderful pop of color and stays compact. In addition, because it is evergreen, it can be used in containers for all seasons and is especially fun in winter when options for grasses are more limited. Acorus gramineus also adds color and consistency to the front of mixed plantings or simple modern plantings where it looks especially good planted en masse. Also, Acorus gramineus can be a fantastic ground cover between pavers in a location where adequate moisture is assured.
Ogon is a gold and green variegation and grows from 10-12 inches tall.
Pests and Diseases: Acorus are prone to slug damage.
