Sansevieria metallica is quite rare. It has a very interesting silvery, horizontally marbled appearance that accents the long swordlike leaves. The tall leaves will provide a contrast in height when planted next to shorter succulents. It looks best when several individual plants are grouped.
Sansevieria metallica prefers semi-shade and should be kept on the dry side. If planted densely it will form a nice background for other, smaller plants.
