Catnip (Nepeta cataria)

Passionflower (Passiflora incarnata)

About

Catnip is a downy, aromatic perennial growing to 3 feet with heart-shaped, gray-green leaves and whorls of white flowers marked with purple spots. Native to Europe and naturalized in North America, it grows in dry wayside places and mountainous regions up to altitudes of 5,000 feet. The plant is gathered when in flower during summer and autumn. Its name comes from the Norse word 'dylla,' meaning 'to soothe,' reflecting its calming properties. Catnip has an excitatory effect on cats but a sedative effect on humans.

Passionflower (Passiflora incarnata and related species) is a climbing vine that can grow up to about 30 ft (9 m). It features ornate, complex flowers - often white, purple, or blue - and lobed leaves. Traditionally recognized for its mild sedative and tranquilizing effects, passionflower helps ease anxiety, restlessness, and insomnia. Some species (e.g., P. quadrangularis) contain serotonin-like compounds, which may contribute to the herb’s calming properties.
