Leaves and flowers may appear together or leaves may be produced later. The base of the leaves and stems are tightly wrapped to form a pseudo-stem or false stem, 5-60 cm long. Flowers in umbels at the top of the stem, leafless, 12-75 cm long. Pseudostems and scapes are often covered with reddish brown to dark purple spots. The flower umbel is in the shape of a globe with 10-200 individual flowers. Each flower has a stalk, 15-45 mm long. The tepals and filaments of the stamens are red. The base of the tepals is fused to form a cylindrical tube, 4-26 mm long, the free end of the tepals 12-32 mm long, narrow and spreading. The fruit is a berry having a diameter of 5-10 mm.
