Dracaena angolensis, synonym Sansevieria cylindrica, also known as the cylindrical snake plant, African spear or spear sansevieria or in Brazil Saint Bárbara sword, is a succulent plant native to Angola. Formerly in the genus Sansevieria, it is now included in Dracaena. African spear plants can survive long periods of drought. And being left in soggy soil or standing water for too long can cause the roots to rot. Let the soil dry out between waterings, and then water the plant deeply. Watering every week to every other week is generally enough, or even less often. If the tips of the blades become dried out, you can begin to water more frequently.
