Habitat & Ecology
In Cornwall, Corn Spurrey is quite a common weed of arable fields on more acid soils, and is also seen in gardens and in waste places where the soil has been disturbed. In arable fields it is often found with Field Woundwort Stachys arvensis . In the Isles of Scilly it is a common and widespread constituent of bulb and other arable fields.
Most sites are unprotected.
