Bletilla ochracea

Bletilla ochracea is a rare variety of terrestrial orchid native to China. It is the only botanical species with yellow flowers among the hyacinth orchids and forms a clump of slender, shiny green foliage from which tall flower spikes emerge in early summer, adorned with flowers ranging from ochre yellow to pale yellow depending on the exposure, enhanced by an orange lip marked with purple. It is adapted to a woodland edge environment and it thrives in non-scorching sunlight or partial shade in moist, light, humus-bearing soil.

Bletilla ochracea belongs to the orchid family. It is native to central-southern China and Vietnam. While it resembles the well-known Bletilla striata, it has a more delicate appearance. The plant grows from semi-buried pseudobulbs, resembling tubers, forming an arc 45 cm long. From spring onwards, it forms a trailing clump that widens over time, composed of broad, arching, soft leaves. In summer, June-July, depending on the climate, it produces stems reaching 60 cm high with small, well-opened flowers, measuring 2.5 cm, ranging from light to dark yellow depending on the exposure, often more ochre on the outside. The flower consists of 3 sepals and 3 petals, one of which is called the lip. The lip of Bletilla ochracea is spotted with vibrant dark orange and purple-pink. The deciduous leaves are medium green, beautifully pleated, up to 30 cm long and 5 to 7 cm wide. The plant produces seeds that seem to produce identical plants to the mother plant.

Bletilla ochracea is cold-resistant down to -20°C and easier to cultivate than other species, as its planting conditions are less demanding. It is one of those terrestrial orchids suitable for gardeners starting their orchid collection. This species requires moist, humus-bearing, well-drained soil in protected, bright locations, but sheltered from scorching sunlight. Its leaves will disappear with the frost, but they will regenerate in early spring. The rhizomatous clump will slowly sucker to form beautiful clusters. Plant Bletilla ochracea in light, moist woodland or even near water features, alongside hostas, ferns, brunneras, or even barrenworts. Bletilla can also be grown in pots to enhance your terraces, in partial shade, and should be overwintered in cold climates.
