Krachai; Chinese Keys; Kachai; Kunci
Zingiberaceae, the ginger family
Java and Sumatra
A tropical perennial herb to 50 - 70 cm tall with underground rhizomes. The leaves are soft green, broad and
emerge on stems rising from the base of the plant. The flowers are pale lilac and grow on short stems from
the outside of the clump. The underground part of the plant consists of a rhizome with fat fleshy rootlets
hanging from it. The rootlets look a bit like a bunch of baby carrots, but are dull beige in colour. This
growth habit is where the common name Chinese Keys derives from. It is native to monsoon forests, requires a
well-drained soil, frost-free climate and 150 cm of rain annually or supplementary irrigation. It thrives
best on loamy or alluvial fertile soils and likes the addition of well-rotted manure or compost.
This rhizome, belonging to the ginger family, is widely cultivated in Thailand for its aromatic, spicy
flavour. It is eaten raw in salads, made into pickles, added to soups and curries especially those made of
seafood. Both the rhizomes and the hearts of stems are eaten raw as a side dish with rice. Young leaves and
shoots, along with the rhizomes , are cut finely, mixed with coconut and spices, wrapped in a banana leaf and
