Chinese ground orchid (Bletilla striata f. gebina)
Discover Bletilla striata f. gebina, the Chinese ground orchid, prized for its creamy white blooms and upright foliage. Perfect for partially shaded gardens.
Complete Plant Information
Overview
The Bletilla striata f. gebina, commonly known as the Chinese ground orchid, offers elegant, terrestrial orchid beauty in temperate gardens. Gardeners prize this variety for its upright habit and delicate, creamy white, cattleya-like flowers that appear early in the season. It provides a unique vertical accent unavailable from more common perennials.
As a robust herbaceous perennial, the Chinese ground orchid thrives when its cultural needs—moist, rich, well-drained soil and partial shade—are met. While it remains hardy in USDA Zones 5 through 9, diligent winter protection is crucial in colder areas to ensure its return next spring.
This orchid introduces sophistication to borders and rock gardens, featuring pleated, rigid foliage that remains attractive even when not in bloom. Growing Bletilla striata f. gebina successfully means providing conditions mimicking its native Eastern Asian habitat for reliable springtime floral displays.

How to Grow
Planting the pseudobulbs of Bletilla striata f. gebina should occur in the spring. Select a location that receives part shade, ideally receiving protection from intense afternoon sun. The crucial factor is the soil: it must be average, well-drained, and consistently medium in moisture. These terrestrial orchids perform best where the soil is organically rich and does not fully dry out, mimicking moist forest floor conditions. Plant the pseudobulbs approximately 1 to 2 inches deep.
Ongoing care involves maintaining even moisture levels throughout the growing season. Water regularly so the soil stays moist but never soggy, which is vital for the health of the Chinese ground orchid. General fertilization is not strictly necessary if the soil is organically rich, but a balanced feeding schedule can support vigorous leaf and flower production. Minimal summer maintenance is required aside from watering.
Winter preparation is essential for longevity, particularly in the northern extent of its range. Gardeners in USDA Zones 5 and 6 must apply a heavy layer of insulating mulch over the planting site after the foliage dies back to the ground. This mulch layer protects the dormant pseudobulbs from hard freezes, ensuring the plant survives to put on its show again the following spring.
Landscape Uses
The refined structure and early bloom time of the Chinese ground orchid make it an excellent candidate for defined edges and textural groupings. Consider using Bletilla striata f. Gebina prominently in borders where its vertical lines contrast nicely with lower-growing, shade-loving groundcovers. They also perform admirably when tucked into rock gardens, provided the soil remains consistently moist, as these orchids dislike sharp drainage accompanied by dryness.
For growers looking for portability or improved winter protection, Bletilla striata f. gebina excels as a container plant. This is particularly recommended for gardeners situated north of USDA Zone 5, as the entire pot can be moved into a protected, non-freezing area (like a cool garage or basement) before the first hard frost, safeguarding the dormant tubers.
When pairing this orchid, look for companions that share its need for part shade and consistent moisture, such as Japanese forest grass (Hakonechloa macra) or various hostas. The ethereal creamy white blooms of the Bletilla striata f. gebina offer a soft counterpoint to deep green or variegated foliage textures in these shaded settings.

Noteworthy Characteristics
Bletilla striata f. Gebina is a terrestrial orchid typically growing up to 18” tall which produces a clump of 3-5, papery but rigid, pleated, linear, upright leaves (6-8” long) and an erect, wiry flower stem containing 6 to 10, creamy white, cattleya-like flowers (1-1.5” wide). Blooms in spring for 3-6 weeks. Foliage dies to the ground in winter.

No specific tolerances were listed in the source data provided for this variety.
Potential Problems
Fortunately, this plant is generally sturdy, reporting no serious insect or disease problems under proper cultural conditions. The most significant threat comes from cultural neglect, specifically allowing the soil to dry out completely or planting in overly dense, poorly draining soil which can lead to rot. Consistent moisture management is the best form of organic pest and disease control for the Chinese ground orchid.
Frequently Asked Questions
What hardiness zones is Chinese ground orchid suitable for?
The Bletilla striata f. gebina is suitable for USDA Zones 5 through 9. Gardeners in Zones 5 and 6 should provide heavy winter mulch protection.
How large does Chinese ground orchid grow?
At maturity, this herbaceous perennial typically reaches a height between 1 and 1.5 feet, with a relatively narrow spread ranging from 0.5 to 0.75 feet.
What sun exposure does Chinese ground orchid need?
This orchid prefers a location with part shade. Avoid harsh, full afternoon sunlight, which can scorch the foliage of the Bletilla striata f. gebina.
When does Chinese ground orchid bloom?
The Chinese ground orchid blooms quite early, generally from April to May, displaying its beautiful creamy white flowers.
Conclusion
The Bletilla striata f. gebina is a standout choice for adding exotic texture and early spring color to partially shaded garden areas. Its manageable size and relatively low incidence of pests make the Chinese ground orchid a rewarding focus plant. Before planting, assess your typical winter weather to ensure you can provide adequate winter protection if you live in Zone 6 or colder.
Companion Planting
Selecting companions for Bletilla striata f. gebina should prioritize shade tolerance and similar moisture requirements. Plants that thrive in consistently moist, rich soil are ideal partners for the Chinese ground orchid. Consider surrounding it with plants that offer varied leaf texture, such as ferns (like Japanese Painted Fern or Autumn Fern) or Astilbe, whose airy plumes complement the orchid’s structure.
Companion planting also helps mask the emergence of the orchid in spring and covers the spot when its foliage eventually dies back in the late fall or winter. Avoid aggressive spreaders, which might overwhelm the slower-growing Bletilla striata f. Gebina, opting instead for well-behaved perennials that share that classic woodland garden aesthetic.
Seasonal Care Calendar
Spring is marked by planting the pseudobulbs shortly after the danger of hard frost has passed; this is also the time to incorporate fresh organic matter into the soil before the foliage emerges. Summer care centers entirely on consistent, medium watering; never let the soil become bone dry, especially when the orchid is actively growing and blooming in April and May.
As temperatures drop in the fall, allow the foliage of the Bletilla striata f. gebina to naturally senesce and die back to the ground; this signals the plant is entering dormancy. Once dormant, apply a thick layer of protective mulch (3-4 inches deep) across the planting zone in colder climates (Zones 5-6) to insulate the dormant tubers until the next growing season begins.
