Heart seed, also known scientifically as Halicacabum, is a plant named for its distinctive seeds. The common name, Heart-seed, comes from the words cardio, referring to the heart and sperma, translating to seed. When ripened, the black seeds feature a white, heart-shaped pattern. The term Halicacabum itself is Latin, describing a plant with inflated fruits. In summary, heart seed is a plant characterized by its heart-shaped pattern on its seeds.
