It's a succulent that grows in clumps of stems with fleshy, dark green to brownish-green leaves with white rounded tubercles. Its leaves are arranged in elongated rosettes, concealing an 8-inch-long stem. They can grow to be up to 2.8 inches long and 0.8 inches wide. From late spring to fall, the mature rosettes produce slender, up to 12-inch long flower stems with tubular white flowers with a greenish-brown midrib.
