Calanthe triplicata, or the Christmas Orchid ia an evergreen, terrestrial orchid with thin dark green, ribbed leaves up to 1 metre long and 15cms wide that rise up out of clumps of fleshy psuedobulbs.
The small, pure white flowers crowd together at the top of 1.5m long erect stems in summer.
Grown mainly in pots, it can also work well in sheltered, shady rock gardens - as much for its foliage as its flowers.
