Catnip (Nepeta cataria)

Peppermint (Mentha x piperita)

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.

Peppermint (Mentha × piperita) is a fast-growing, square-stemmed herb (commonly about 32 in / 80 cm tall), with lanceolate, serrated leaves and purplish flowers. A natural hybrid of watermint and spearmint, peppermint is renowned for its cooling, aromatic flavor and its therapeutic benefits in alleviating digestive and respiratory complaints.
