A Nobile-type Dendrobium. Easy to grow, great for mounting, and fragrant. Deciduous and pendulous, they require a cool, dry rest in fall/winter. They bloom winter into the spring. This orchid does best in a bright, but shaded spot, but no direct sunlight. Temperature: Dendrobium nobile loves a cool and well-aerated setting with a temperature between 55 - 75 degrees F.
