A plant producing dark or black seeds; possibly referring to nigella or similar plants with dark seeds.
From black (color characteristic) + seed (reproductive material of plants). Describes plants by their most visible distinguishing feature.
Nigella sativa (black seed) was traded for thousands of years as medicine and spice, yet mostly forgotten in Western herbalism — rediscovering it meant relearning what grandmothers in other continents never forgot.
