Charred grains, seeds, and fruits found in Late Roman Iron Age cultural layers from the Katajamäki excavation were studied. Sampling problems are discussed; the material forms an unbiased sample taken evenly from all interesting-looking objects. Archaeobotanical and archaeological results, obtained independently, show surprising correspondence. A preliminary plant list is given: barley, emmer, bread wheat, oat, and flax were cultivated. Many wild fruits -- e.g. hazel, wild strawberry, raspberry, and bird-cherry -- were collected. Many charred finds of weed and ruderal seeds might indicate their possible use for food.
