A plant seed with a golden color, or a seed that produces gold-colored flowers or fruit.
From 'gold' + 'seed.' This is a descriptive compound combining color with the object being described, common in botanical naming.
Many plants have color-based common names like 'goldseed,' 'blackseed,' or 'redseed,' which shows how people learned to identify and communicate about plants long before scientific taxonomy—color was the most obvious feature to notice.
