Catnip
Catnip is a versatile member of the mint family, loved for its dual-purpose appeal. While it acts as a stimulant for cats, providing endless entertainment, it has a calming effect on humans, making it perfect for relaxing night-time teas.
Growing to 1m (3ft) tall, this hardy perennial features soft, fuzzy leaves and delicate flowers, adding charm to herb gardens or mixed borders. Catnip is drought-tolerant and deer-resistant, making it a low-maintenance choice for gardeners.
