Bletilla striata is a species of Chinese ground orchid known as the Chinese Bletilla or Hardy orchid. It boasts striking purple or pink flowers that bloom in late spring or early summer. Their unique feature lies in their flared petals, creating an exquisite display in gardens and landscapes.
Bletilla Ochracea

With its distinct purple or lilac flowers, Bletilla formosa captivates orchid enthusiasts. Known as the Chinese Bletilla or terrestrial orchid, it adorns gardens in late spring or early summer. This species is renowned for its upright stems and a pleasant fragrance.
Related Orchid Species
Beyond the distinct species of Chinese ground orchids, the Bletilla genus, there are other closely related orchid species that share similar characteristics and habitats.
One such related species is Pleione yunnanensis, also known as the Yunnan pleione. Like Chinese ground orchids, Pleione yunnanensis is terrestrial, meaning it grows in soil rather than on trees. It boasts deciduous leaves that die back in winter, and its pseudobulbs store nutrients during the dormant season.
However, Pleione yunnanensis differs from Chinese ground orchids in its flowering characteristics. It produces single, fragrant flowers that bloom in shades of pink or purple in the spring. Additionally, its pseudobulbs are elongated and ovoid, unlike the disk-shaped pseudobulbs of Chinese ground orchids.
The Bletilla genus also has other related terrestrial orchid species, including:
- Bletilla japonica: Features white or pale purple flowers, blooms in spring
- Bletilla yoshinoi: Produces orchid-pink flowers, blooms in summer
- Bletilla coreana: Smaller in size, with purple-striped flowers that bloom in spring
These related orchid species offer a range of ornamental values, making them popular choices for gardening. They thrive in similar growing conditions as Chinese ground orchids and provide a beautiful addition to shady areas or woodland gardens.
