Calanthe is a genus of terrestrial orchids comprising over 200 species native to tropical and subtropical regions of Asia, Africa, and the Pacific Islands. These captivating orchids are sought-after for their elegant flowers, fascinating growth habit, and adaptability to a range of growing conditions.

Growth Habit: Calanthe orchids are terrestrial, meaning they grow in the ground rather than on trees like many other orchid species. They produce large, pleated leaves that form a basal rosette and provide a lush, green backdrop to their stunning flowers. The plants are deciduous or evergreen, depending on the species, with some shedding their leaves during winter dormancy.

Hardiness: Calanthe species vary in their hardiness, with some being more tolerant of cooler temperatures than others. Generally, they prefer moderate temperatures ranging from 50-85°F (10-29°C) during the day and slightly cooler temperatures at night. Some hardy species, like Calanthe sieboldii and Calanthe discolor, can withstand brief exposure to freezing temperatures if properly protected.

Flowers: Calanthe orchids are prized for their showy, fragrant flowers that bloom in an array of colors, including white, yellow, pink, purple, and red. The flowers are borne on tall, erect spikes that rise above the foliage, creating an impressive display. Blooming typically occurs in spring or early summer, depending on the species.

Uses: Calanthe orchids are excellent additions to shade gardens, woodland settings, or as container plants in temperate regions. They can be used as focal points, mass-planted for a stunning effect, or combined with other shade-loving plants in mixed borders.

Benefits: Calanthe orchids are not only visually captivating, but they also provide habitat for pollinators like bees, butterflies, and moths. Some species are even known for their medicinal properties in traditional medicine practices.

To grow Calanthe orchids successfully, provide them with dappled shade or filtered sunlight, as the direct sun can scorch their leaves. They prefer a well-draining, humus-rich soil that retains moisture. Water regularly to keep the soil evenly moist but avoid overwatering, as this can lead to root rot.
