Chinese Ground Orchid Bletilla striata
ABOUT
Commonly known as the Chinese ground orchid, Bletilla striata presents itself with an alluring visual display that adds an exotic touch to gardens. Its foliage consists of pleated, linear leaves that form a graceful, fan-like cluster. These leaves emerge in spring, offering a lush, green backdrop for the remarkable flowers that follow. The blooms of the Chinese ground orchid are notable for their orchid-like appearance. Each inflorescence carries multiple flowers that dangle gracefully from a central stalk. The flowers are typically purple or lavender-pink in color, sometimes with a hint of pale violet, and have a delicate, soft texture that suggests refinement and elegance. Showcasing a trademark orchid structure, the flowers consist of a lip, also known as a labellum, which often exhibits a ruffled or fringed margin, adding to their intricate allure. The interior of the lip is usually marked with complementary color patterns, which may include spots or striations that provide additional visual interest and help attract pollinators. The Chinese ground orchid has a clumping growth habit, forming a pleasing clump of both flowers and foliage. With time, it can spread to form a larger cluster, though not overwhelmingly so. Its appearance harmonizes well with other shade-loving perennials and it is often found adding a splash of color and tropical flair to woodland gardens or shaded areas. This plant is a favorite among gardeners seeking a touch of the exotic without requiring the care that more delicate tropical orchids might demand.

WaterThe Chinese Ground Orchid should be watered regularly during its active growth period, usually from spring to early fall, ensuring the soil is kept moderately moist but not waterlogged. Water the plant every 5 to 7 days, providing about 16 to 24 ounces of water each time, allowing the top inch of soil to dry slightly between waterings. During dormancy in late fall and winter, reduce watering frequency to every two weeks, with a lighter amount of water, approximately 8 to 16 ounces, just enough to prevent the soil from completely drying out.
LightThe Chinese Ground Orchid thrives best in partial shade with some morning sun or dappled light throughout the day. It is not suited for direct harsh afternoon sunlight, which can scorch its leaves. An ideal spot for this plant is under the canopy of tall trees or on an east-facing windowsill that receives gentle sun exposure.
TemperatureThe Chinese Ground Orchid prefers temperatures between 65 to 75 degrees Fahrenheit during the day, and it can tolerate a minimum nighttime temperature down to 40 degrees Fahrenheit. The plant can survive brief periods of cold, but extended exposure to temperatures below freezing can be harmful. Optimal growing conditions fall within this temperature range to promote healthy growth.
PruningPrune the Chinese Ground Orchid to remove any dead or yellowing leaves as needed to keep the plant healthy and promote air circulation. The best time for pruning is after the flowers have faded and the leaves start to die back, usually in late summer or early fall. Generally, pruning once a year at this time is sufficient.
CleaningAs needed
SoilThe Hard Ground Orchid thrives in well-draining, moisture-retentive soil with a mix of bark, perlite, and loam. A slightly acidic to neutral pH of 5.5 to 7 is optimal for this plant.
RepottingThe Hard Ground Orchid should be repotted every two to three years or when the potting mix breaks down or the plant outgrows its pot.
Humidity & MistingThe Hard Ground Orchid prefers high humidity levels, ideally between 40% to 70%, to mimic its natural humid environment.
Suitable locationsIndoor
Place in bright, indirect light with high humidity.
Outdoor
Plant in dappled shade with moist, well-drained soil.

Life cycleThe Chinese ground orchid (Bletilla striata) starts its life cycle from a pseudobulb or seed, with the former being more common in cultivation. Upon germination, seedlings or new shoots from pseudobulbs emerge and develop into small plants with thin leaves. As the plant matures, it forms a rosette of pleated leaves and strengthens its pseudobulb for nutrient storage. During spring and early summer, the Chinese ground orchid blooms, producing elegant purple-pink flowers on a spike that can reach up to a foot in height. After flowering, the plant enters a period of vegetative growth, where it stores energy in its pseudobulb for the next season. Finally, in the fall, as temperatures decrease, the Chinese ground orchid becomes dormant, with above-ground foliage dying back, and it remains dormant through winter until the cycle restarts with warmer spring temperatures.
PropogationPropogation time
Spring to summer
Bletilla striata, commonly known as the Chinese ground orchid, can be propagated most effectively by dividing its pseudobulbs, typically in the spring before new growth emerges. Carefully dig up the clump of orchids and gently separate the pseudobulbs, ensuring that each division has at least one growth point. These divisions can then be replanted in well-drained soil at a depth of about 3 inches (roughly 7.6 centimeters), spaced approximately 6 to 12 inches (15 to 30 centimeters) apart to allow for adequate growth. It's essential to maintain consistent moisture without overwatering and provide the plants with dappled shade, mimicking their natural habitat. With the right conditions, these divisions will establish themselves and can bloom within a year or two.
