About
Roscoea humeana is a species of flowering plant in the family Zingiberaceae. It is a perennial occurring in the Sichuan and Yunnan provinces of China. Most members of the ginger family, to which it belongs, are tropical, but R. humeana, like other species of Roscoea, grows in much colder mountainous regions. It is also grown as an ornamental plant in gardens.
How to grow it
Some Roscoea species and cultivars, including R. humeana, are grown in rock gardens. They generally require a relatively sunny position with moisture-retaining but well-drained soil. As they do not appear above ground until late spring or even early summer, they escape frost damage in regions where subzero temperatures occur. R. humeana was described in 1999 as "one of the more popular species" that had been cultivated for many years. When grown at Royal Botanic Gardens, Kew, it flowers in May and June before the leaves have fully expanded. When they have, after flowering, this is one of the largest species of the genus in cultivation. It prefers some shade.
Where it grows
Roscoea humeana occurs in a variety of habitats, such as pine forests, scrub, meadows, grassy and rocky areas, and limestone cliffs, between 2,900 and 3,800 metres in the Sichuan and Yunnan provinces of China.
