Definition of oxalis in English:



  • A plant of a genus that includes the wood sorrel, typically having three-lobed leaves and white, yellow, or pink flowers.

    • ‘Semi-tropical natives such as dahlias, gladioli, begonias, canna, caladium, elephant ears, oxalis and other tender summer-flowering bulbs will not make it through the winter outside of the warmest climate zones.’
    • ‘This was the weedmat that defeated my oxalis and couch grass.’
    • ‘Double-pot small plants or those that dry out quickly such as oxalis, laying in a layer of moist peat between the two pots.’
    • ‘If possible, weed the unwanted oxalis in flower beds rather than use a herbicide, which may damage or kill your more desirable plants.’
    • ‘Ferns are especially handsome as accents among swaths of lower-growing plants such as sweet woodruff or oxalis or growing beside ponds.’


Early 17th century: via Latin from Greek, from oxus sour (because of its sharp-tasting leaves).
