They form a low growing, vase-like rosette of broad elliptic spirally-arranged leaves. Plants form clumps growing to 12 inches tall with an equal spread, are very robust and sucker freely. Sanseviera trifasciata 'Hahnii' will survive in a wide range of conditions. They tolerate low light conditions and are very drought tolerant.Too much water tends to rot the plants at the soil line. Plant are fertilized only once during the growing season with a balanced fertilizer. Propagation: Offsets, leaf cuttings on non variegated forms. Sansevieria trifasciata 'Hahnii' are propagated by the removal of suckers at any time of the year.
