About this plant
Roscoea purpurea f. rubra is an elegant perennial featuring orchid-like, deep reddish-purple flowers that bloom from mid-summer to early fall. The blossoms emerge in clusters, with each flower having delicate, elongated petals that resemble small orchids, adding a touch of elegance to the garden. The flowers stand out beautifully against the lush, narrow green leaves.
Native to the mountainous regions of the Himalayas, Roscoea purpurea f. rubra thrives in cooler climates and brings an exotic charm to borders and shaded garden areas. Its unique blooms and extended flowering period make it a popular choice for adding color and interest to late-season garden displays.

Design tip
Late flowers extend the season, so set it behind or beside plants that finish in midsummer. Cooler light suits it, so tuck it on the north side of a shrub or wall where the soil stays even.
Where to see it
