Catnip is a perennial herb prized for its aromatic foliage and potent effects on felines. These seeds germinate readily in well-draining soil with consistent moisture and full sun exposure. The plant thrives in USDA zones 3-9, reaching 2-3 feet at maturity. Harvest leaves once the plant is established for fresh use or drying. Beyond entertaining cats, catnip offers culinary and medicinal applications—brew dried leaves for a soothing tea or use fresh sprigs in cooking. A reliable, low-maintenance addition to any herb garden.
