Bitter herbs. מָרוֹר mārôr - Strongs: H260.
From Wikipedia: Maror - The Mishnah specifies five types of bitter herbs eaten on the night of Passover: ḥazzeret (lettuce), ʿuleshīn (endive/chicory), temakha, ḥarḥavina (possibly melilot, or Eryngium creticum), and maror (likely Sonchus oleraceus, sowthistle). The most common vegetables currently used as bitter herbs are horseradish and romaine lettuce.
