Wild sourced landraces used to propagate all native seed crops

EC: Landraces Seed mixtures, biodiversity products of Native Species blended as a Wildflower Seed Mixture.
E.U Terms: Landraces, Part-’Conservation’ Mixture as it contains a percentage of wild meadow harvested seed along-side, crop seed and crops seeds of wild forms of species described in Preservation mixtures, alongside wildgrass of ‘Uncertified’ varieties.

The term ‘Wildform Landraces of near ’pre-pre-basic’ seeds’ would best describe each species. Mixes containing species may be defined by as ‘alike’ but not ‘preservation or conservation’
