Hedychium coronarium, commonly known as the butterfly ginger or "Shannai" spike flower, is a striking ornamental plant native to southern China. This perennial herb belongs to the Zingiberaceae (ginger) family and is renowned for its beautiful, butterfly-like flowers that bloom from May through November.
The plant typically grows between 1 to 2 meters in height, with aromatic underground rhizomes. Its inflorescence consists of 10 to 15 showy flowers, which come in various colors such as white, orange, and yellow. Each flower has four petal-like structures, resembling butterfly wings, which give it its common name. The true reproductive parts—stamens and pistils—are closely grouped at the center, making the flower both visually appealing and functional for pollination.
The calyx is composed of three sepals, while the petals are often brightly colored and attract pollinators. The upper part of the flower has a light-colored base and contains pollen, further enhancing its resemblance to a fluttering butterfly. These flowers often grow in clusters, adding to their visual impact and making them a popular choice for gardens and floral arrangements.
The fruit is a capsule that turns brown when mature. It contains seeds covered in a thin, membranous layer. Hedychium coronarium thrives in warm, humid climates and prefers partial shade, well-drained, slightly acidic loam soil that is rich in organic matter.
This plant was introduced to Taiwan during the Japanese era from India and other regions. It has since become widely cultivated across the country, particularly in central areas. It is not only admired for its beauty but also valued for its economic and medicinal uses.
In horticulture, the butterfly ginger is a popular choice for potted plants and cut flowers due to its elegant appearance. It can be planted in small courtyards, where it adds a touch of natural beauty and serenity. In addition to its ornamental value, the plant is also used in the fragrance industry. The essential oils extracted from its rhizomes are highly prized, with prices several times higher than gold.
Medicinally, Hedychium coronarium is recognized in traditional Chinese medicine. It is listed in the Chinese Pharmacopoeia and is known by various names such as "roadside ginger" and "earth ginger." According to historical texts like "Sichuan Traditional Chinese Medicine," it is described as sweet, warm, and non-toxic. It is used to treat conditions such as headaches, body aches, rheumatism, and bruises. The rhizome is typically harvested in winter, dried, and used in decoctions, with a recommended dosage of 3 to 5 grams. The roots contain volatile oils, including aldehydes, eucalyptus compounds, and sesquiterpenoids, contributing to its therapeutic properties.
