Description
Catnip (Nepeta cataria) is a hardy perennial herb in the mint family (Lamiaceae), famed for its euphoric effect on cats but also valued as a medicinal plant for people. Native to Europe and Asia, it forms a loose, bushy clump of soft, grey-green, downy leaves with a strong, somewhat pungent aroma. In summer, it produces clusters of white to pale lilac flowers speckled with purple.
Catnip thrives in full sun to part shade and well-drained soils, tolerating poor soils and drought once established. In New Zealand, it is hardy to frosts and will often self-seed. Plants grow to about 60–100 cm tall and 60 cm wide.
Medicinally, catnip has long been used as a calming herb, particularly for children. A gentle tea can ease digestive upsets, restlessness, and sleeplessness. It is also mildly diaphoretic, supporting fevers by encouraging gentle sweating. For cats, the leaves provide enrichment and entertainment — not all cats respond, but many enjoy its stimulating effect.
