The Dendrobium genus is one of the largest of all orchid groups with nearly 2,000 species. Native to southeast Asia, these plants grow in all manner of climates—from hot, wet lowlands to high-altitude, cool mountains. Dendrobiums are primarily epiphytes, meaning they grow on other plants. In nature, they're often found growing on tree branches. While the species vary in appearance, all of them are known for their profuse blooms that come in a variety of pastel tones. Some species bloom all along the lengths of their stems while others bloom just from the tops of the stems. Some are deciduous and drop their leaves in the fall, and some hold on to their leaves year-round. Most species have a moderate to fast growth rate. The best time to plant is either at the very beginning of the growing season or after the orchid has finished flowering.

Dendrobium Orchid Care
Dendrobium orchids make good houseplants and are fairly easy to grow, though they can be picky about their environment. Thus, paying close attention to their growing conditions is key for a healthy, well-blooming plant. In general, these orchids like small pots where their roots can be somewhat cramped, and they need to be by a bright window if you're keeping them indoors. Plan to water and feed your orchid often during the growing season but then back off in the winter months.

These plants generally send up at least one new upright cane each year. Don't cut off old canes, as they store nutrients and water to keep the orchid healthy. Old canes also will sometimes flower or produce tiny plants, called keikis, that can be potted on their own after they develop roots. The long-lasting sprays of flowers remain in bloom for roughly six to eight weeks, and they can make excellent cut flowers. In optimal conditions, your plant might bloom multiple times per year. If blooming seems suboptimal, try providing your orchid with more light.
