Plant Information

Ogon is a gold and green variegation and grows from 10–12 inches tall.

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.

Pests and Diseases: Acorus are prone to slug damage.
