This study explored the potential of Asparagus densiflorus to treat disperse Rubin GFL (RGFL) dye and a real textile effluent in a constructed vertical subsurface flow (VSbF) phytoreactor. Field cultivation of A. densiflorus decolorized RGFL (40 gm/L) up to 91% within 48 h. The VSbF phytoreactor successfully reduced American dye manufacture institute BOD, COD, total dissolved solids (TDS), and total suspended solids (TSS) of real textile effluent by 48-66% within 6 d. Anatomical study of the advanced root tissue of A. densiflorus exhibited progressive dye accumulation and removal during phytoremediation. One field remediation study revealed 67% dye removal from polluted soil within 30 d.
