Sansevieria kirkii cv. Silver Blue is one of the nicest Sansevieria distinguished by its unique super chunky silver blue foliage patterned with darker longitudinal lines and mottling. It is often named simply Sansevieria 'Silver Blue' as it remains to be seen if this plant is related to Sansevieria kirkii or not. For this reason many growers use the cultivar name only, and not the species name kirkii. The leaves are exceptionally thick and shorter, and seem different from the S. kirkii. Silver Blue is a very beautiful still a rare collector's plant. Bright light brings out the best leaf color. The flower is greenish-white, scented, and has a conical inflorescence.
