Dendrobium Orchid

Dendrobium Orchid

　　Dendrobium, also known as Dendrobium Orchid, is a plant of the genus Dendrobium in the orchid family. It is native to the Himalayas and surrounding areas and is one of the earliest recorded orchid species in ancient Chinese literature. With its beautiful flower shapes, elegant postures, vibrant colors, wide variety, and long blooming period, it is beloved and admired by people around the world and holds an important position in the international floral market. Today, it is widely cultivated in many countries around the world, especially in Southeast Asia, where Thailand has the largest production. In 1993, Thailand produced 3,600 tons of Dendrobium Orchids, and in 1994, exported 62.9 million stems to Italy, 14.25 million to the Netherlands, and 11.7 million to Germany, as well as exports to Japan and North America. Additionally, Singapore, Malaysia, and Taiwan (China) also have a certain level of production, with major export destinations including the Netherlands, Germany, Italy, the United Kingdom, France, and Japan. The Philippines mainly produces for domestic consumption. In Asia, Japan is the largest importer of Dendrobium Orchids, with 2.3 million pots sold in 1993, generating sales of $28 million, ranking sixth in potted flower sales.

　　Large-scale production of Dendrobium in China started relatively late, mainly from the early 1990s. Despite the late start, the development has been rapid. To date, there are production bases of considerable scale in Guangdong, Kunming, Fujian, and other regions, which can basically meet the domestic market demand for both potted and cut flowers.

　　The Dendrobium genus is the largest in the orchid family, with its native distribution mainly in tropical and subtropical Asia, Australia, and Pacific islands, comprising about 1,000 species worldwide. China has approximately 76 species, most of which are found in tropical and subtropical regions such as the southwest, south, and Taiwan, as well as areas south of the Qinling Mountains. They grow at altitudes between 100 and 3,000 meters, often epiphytically on trees or rocks. This genus consists of epiphytic orchids with highly diverse morphological characteristics.

　　The pseudobulbs grow in clusters, cylindrical or slightly flattened, tapering at the base; leaves are papery or leathery, oblong, with two rounded apical splits; inflorescence is a raceme; flowers are large, semi-pendulous, in white, yellow, light rose, or pink, vibrant and beautiful, with many varieties emitting a fragrant aroma.

　　The Dendrobium genus is a sympodial epiphytic orchid with nearly a thousand original species, making it one of the larger genera in the orchid family. Its native range is very broad, spanning from Japan and Taiwan in Asia to Thailand, Indonesia, Malaysia, and even Australia and New Zealand. The spring Dendrobium of Japan and the autumn Dendrobium of Thailand, Singapore, and Hawaii are the most famous, especially as Thailand is often associated with autumn Dendrobium.

　　Dendrobium is divided into two types: spring Dendrobium, or the Nobile series, which blooms in spring with flower spikes emerging from the sides of the stems, and autumn Dendrobium, which blooms in autumn with flower spikes emerging from the top of the stem, each spike bearing one to twenty flowers. Flower forms include the large-flowered butterfly orchid type (Phalaenopsis series) and small-flowered curled-petal types.

　　Cultivation-wise, they are divided into temperate deciduous types (spring Dendrobium) and tropical evergreen types (autumn Dendrobium). Spring Dendrobium flowers typically grow between stem nodes, with a blooming period of about 20 days, and are mostly used as potted ornamental plants. Autumn Dendrobium flowers usually grow at the top of the stem, with a blooming period of over a month, and are primarily used as cut flowers. The pseudobulbs can be used medicinally. Propagation is done through division, stem cuttings, or sterile seeding. They prefer warm, humid, and semi-shaded conditions; use loose, breathable substrates such as fern roots, moss, or bark chunks for potting. During the growing season, maintain humidity and partial shade, with appropriate fertilization; in winter, keep drier with stronger sunlight. Overwintering temperature should be above 10°C.
