Veronica persica

Tracheophyta MagnoliopsidaScrophulariaceaeVeronicaVeronica persica


An annual of arable fields, other cultivated areas and waste ground, found on a wide range of fertile soils. It is self-fertile and seeds prolifically, the seeds forming a persistent seed bank and germinating throughout the year. It also spreads vegetatively from stem fragments. 0-350 m (Alston, Cumberland).



World Distribution

Probably native to mountains of the Caucasus & N. Iran, where it may have originated by the hybridisation of V. ceratocarpa and V. polita. Widespread as a weed in Europe, N. Africa, N. America, Japan and New Zealand.
