''Veronica chamaedrys'' is a common, hardy turf so-called weed when it invades turf and lawns. It creeps along the ground, spreading by sending down roots at the stem nodes. It is propagated both by seed and stem fragments. Leaves may defoliate in the summer and winter but the stems will grow again next season. Unlike at least five other common speedwell species, such as corn speedwell (''Veronica arvensis''), the
leaves are opposite on both the upper and lower parts of the plant. See ''
Veronica'' for special weed control considerations.
