An annual of arable land and open waste ground, usually on calcareous soils, in similar habitats to K. elatine and often growing with it. Lowland.
Like K. elatine, this species has a similar range to that mapped in the 1962 Atlas. Although both species are often thought to be declining, they have never been abundant weeds and the distribution may be more stable than is often supposed.
As an archaeophyte K. spuria has a European Southern-temperate distribution.
