Dendrobium is a large genus of orchids, comprising over 1,800 species. These plants are primarily found in tropical and subtropical regions of Asia, Australia, and the Pacific Islands. They are known for their diverse shapes, sizes, and colors, making them popular among orchid enthusiasts and collectors. Dendrobium orchids typically grow as epiphytes, meaning they thrive on other plants without harming them. They have unique growth patterns, with some species producing long, slender stems and others forming compact clusters. Many Dendrobium species are also cultivated for their beautiful flowers, which can last for several weeks.
