Blyxa japonica is an obligate aquatic plant often found in stagnant, shallow pools and marshes as well as in slow moving, iron-rich forest streams in tropical eastern Asia. It can also be found in man-made habitats (such as rice paddies) throughout its range.
The plants you receive may, or may not be in this submerged form. New shipment of plants may be in their emerse form which is green in color and looks different in shape.
