Mesolithic

Garden Orach (Atriplex hortensis L.) is a vegetable plant of minor importance but with a wide distribution throughout the Old World and beyond. Previous research revealed its diverse medicinal and magical importance in prehistory. Here, Orach’s special ability to retain sodium even in non-saline ground is introduced. The outstandingly high concentrations of sodium in dry plant matter and plant ash suggest its use as a salt substitute, manifested in an early domestication trait. Special attention is paid to the variability of this trait in cultivars from different geographic regions and within the genus Atriplex. ..

Introduction

A wild seed propagator and gardener (such as myself) relies on years of close human-plant interaction. The adaptability of domesticated and many wild plants to human economy and behaviour has always thrilled me. When I first read archaeological reports of frequent and large amounts of prehistoric charred seeds that were dumped in the ground I was bemused. It contrasted starkly with the care and sensitivity I use in the processes of seed harvest, drying and selection. So I started reading more and also charring seeds myself.
