Plant Description

It is herbaceous perennial herb, 0.5-1.5 m tall, with rhizomatous growth.

The plant consists of clumps of herbaceous and erect pseudostems, or above-ground shoots, approximately 75 cm tall, that emerge from an underground rhizome.

Leaves are large, simple, and oblong or lance-shaped. They are arranged alternately on the stem. Leaves are dark green and smooth, with prominent parallel veins. Leaf margins are entire.

The flowers are bisexual, irregular, and arranged in a dense, spike-like inflorescence. They are yellow with red or purple bracts and are small and tubular. The spike can reach up to 25 cm in height. The base of the spike has white and green bracts, while the tips feature pink bracts.

Fruit is a capsule, containing several seeds. The capsule is usually not produced in cultivation as the plant is often harvested before flowering.
