5 Seeds Costus speciosus Spiral Ginger Tropical Ornamental

Costus speciosus, commonly known as Spiral Ginger or Crepe Ginger, is a tropical ornamental perennial prized for its tall, spiraling stems and dramatic crepe-textured blooms. The plant grows from thick, fleshy rhizomes and produces bold, paddle-shaped leaves arranged in a graceful spiral around each stem, creating an architectural look in warm-climate gardens and large containers.

Spiral Ginger is grown primarily for its ornamental value in tropical and subtropical landscapes, where its lush, upright form works well as a backdrop planting, around water features, or in large patio pots. It prefers warmth, consistent moisture, and bright filtered light, and it spreads slowly by rhizome to form a full clump over time. In cooler zones it can be grown in containers and overwintered indoors or lifted before frost.
