Black Henbane (Hyoscyamus niger) is a striking ornamental flowering plant valued for its dramatic yellow-purple veined blossoms and its association with traditional medieval gardens. This rare nightshade family plant adds unique texture and color to themed landscapes and collector’s gardens.
A biennial herb, it forms rosettes of soft, hairy leaves in its first year and produces tall flowering stalks in the second. Black Henbane prefers sunny locations with well-draining soil and moderate watering. Grown responsibly as a botanical ornamental, it enhances the aesthetic of historical or curiosity gardens.
