Synonyms[1]

Bletilla striata, known as hyacinth orchid[2] or Chinese ground orchid,[3] is a species of flowering plant in the orchid family Orchidaceae, native to Japan, Korea, Myanmar (Burma), and China (Anhui, Fujian, Gansu, Guangdong, Guangxi, Guizhou, Hubei, Hunan, Jiangsu, Jiangxi, Shaanxi, Sichuan, Zhejiang).[1][4] It is most commonly found growing in clumps alongside grassy slopes with sandy soil.[5]

The Latin specific epithet striata means "striped", in reference to the ribbed leaves.[6]

Description

Bletilla striata is a terrestrial orchid with pleated, spear-shaped leaves. It breaks dormancy in early spring, with each tuber of the previous year potentially sending out multiple shoots. These growths mature over the course of a couple months and eventually bear 3-7 magenta-pink flowers.[7]

Cultivation

In cultivation in the United Kingdom it is hardy in sheltered locations down to −10 °C (14 °F). It has gained the Royal Horticultural Society's Award of Garden Merit.[2]

In the U.S. it may be grown in USDA hardiness zones 5–9, although a winter mulching for plants grown in zone 5 is recommended.[7]

Like most terrestrial orchids, it drops its leaves as it enters winter dormancy; however, it tolerates moisture during this period much better than most others. Nevertheless, it is encouraged to grow Bletilla striata in a well-draining, humus-rich mix.[8]

Uses

Bletilla striata is used in Asian traditional medicine for treating problems with the lining of the alimentary canal, e.g. ulcers.[9]

It is also used as a natural glue for making silk strings for traditional Chinese instruments like the guqin.[10]
