Description: Acorus gramineus narrow leaves, which grow in a dense clump or tuft rising from a slender rhizome that lies just below the surface of the potting mixture, are up to 45cm (18 inch) long. There is a green slower spathe, but is is barely noticeable since it is so fine that it looks almost like another leaf.
Houseplant Care: Acorus gramineus grow more or less continuously, but its active growth will slow down under reduced light.
Light: Medium light or direct sunlight filtered through a translucent blind or curtain will suit Acorus gramineus.
Temperature: An indoor Acorus gramineus will grow well in normal warm room temperatures, but can also tolerate temperatures as low as 4??C (39??F). High humidity is essential; stand plants on trays of moist pebbles throughout?? the year and mist-spray the leaves during the warm periods.
Water: Because they are marsh plants, Acorus gramineus needs more water than most other types of plants. These plants must never be allowed to dry out at the roots. Water plentifully as often as necessary to keep the potting mixture thoroughly moist. The pot may even?? be allowed to stand in shallow saucer of water.
Gardening: Acorus gramineus when grow outdoor is easily grown in average, medium to wet soils in full sun to part shade. Grows well in both boggy conditions (including very shallow water) and consistently moist garden soils. Scorched leaf tips will occur if soils are allowed to dry out. Appreciates some relief from hot summer sun (e.g., afternoon shade or filtered sun) when grown in hot summer climates. Slowly naturalizes by spreading roots, but is not too aggressive.
Acorus gramineus can be planted in baskets in shallow water. It also makes a useful aquarium plant but is short-lived where water temperatures exceed 22℃ for long periods. Divide every few years to prevent congestion.
