Haworthia gigantea, Haworthia limifolia var. gigantea
The variety is native to South Africa and restricted to a few locations in KwaZulu-Natal.
Haworthiopsis limifolia var. gigantea, formerly known as Haworthia limifolia var. gigantea, is a stemless succulent that forms large compact rosettes of dark green to brownish-green leaves covered with irregularly arranged light green to nearly white tubercles. It has small raised tubercles instead of the transverse ridges characteristic of Haworthiopsis limifolia var. limifolia. The rosettes grow up to 4 inches (10 cm) tall and 9.2 inches (23 cm) in diameter. Leaves are ovate–lanceolate, up to 4.4 inches (11 cm) long and 1.6 inches (4 cm) wide. The upper surface of the leaves is concave with an oblique marginal longitudinal ridge in the upper three-quarters. The lowers surface is convex, usually with a narrow oblique longitudinal depression. Flowers are small, white with greenish-brown midrib, tinged with pink at tips, and appear spirally arranged on a slender, up to 30 inches (75 cm) long peduncle, including the raceme in spring and summer.
The varietal epithet "gigantea (jy-GAN-tee-uh)" is the feminine form of the latine adjective "giganteus," meaning "giant," and refers to the uncommonly large size of the variety.
