Growing up to 80 cm tall, it forms purple stems that may arch and root into the ground. This slow-growing plant is primarily cultivated indoors for its decorative foliage and rarely blooms in cultivation. The plant produces distinctive cream-colored labiate flowers arranged in vertical spikes, followed by loculicidal capsules containing seeds.
