Dracaena angolensis 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. Description Dracaena angolensis has striped, elongate, smooth, greenish-gray subcylindrical leaves. They are up to diameter and grow up to above soil. The spear sansevieria grows fan-shaped, with its stiff leaves growing from a basal rosette. The species is interesting in having subcylindical instead of strap-shaped leaves caused by a failure to express genes which would cause the cylindrical bud to differentiate dorsoventrally or produce a distinctive and familiar top and bottom surface to the leaf blade. The greenish-white tubular flowers are tinged with pink. Cultivation The species is drought-tolerant and in cultivation requires water only about once every other week during the growing season. The species can be watered once a month during the winter months. The species was described by Wenceslas Bojer in 1837. Dracaena angolensis (under the synonym Sansevieria cylindrica) received its common name from a competition in a Dutch national newspaper. It is popular as an ornamental plant as it is easy to culture and take care of in a home if given bright sunlight and other required resources.
