Sansevieria cylindrica

Sansevieria cylindrica, also known as the cylindrical snake plant, African spear or spear sansevieria, is a succulent plant native to Angola.
Sansevieria cylindrica has striped, round leaves that are smooth and a green-gray color. A single leaf is about 3 cm (1 in) thick and grows to a height between 1 m (3 ft) and 2 m (7 ft). The Spear Sansevieria grows fan-shaped, with its stiff leaves growing from a basal rosette. The species is interesting in having rounded 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 3 cm (1 in) greenish-white tubular flowers are tinged with pink. The species is drought-tolerant and in captivity needs water only about once every other week during the growing season. The species was described by Wenceslas Bojer in 1837. Sansevieria cylindrica received its 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.
