Many weed species have populations which are distinct in form or physiology from other populations of the same species. To enable comparisons to be made between individual populations of certain weeds, Herbiseed stocks small quantities of seed from several separate geographical origins. Many of these are listed in the table below. Only small quantities are available, priced at £30/€50/$60 per 25g. Please e-mail your requirements because our online ordering system can’t handle multiple populations
For 8 different biotypes of Echinochloa crus-galli, please go to the Echinochloa entry in the main weed table.
