金錢菖蒲 Golden Sweet Flag ( Acorus gramineus )

 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.  

Acorus gramineus grow more or less continuously, but its active growth will slow down under reduced light.  

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℃
