nepeta cataria - catnip

Nepeta cataria (Catnip) is an ornamental, erect perennial herbaceous plant that grows to 20–39 inches high, which are very leafy and covered with a mealy down. The heart-shaped, toothed leaves are likewise covered with a soft, close down, especially on the undersides, which are quite white with it, so that the whole plant has a hoary, greyish appearance, as though it had had the dust blown over it. It has little white or lilac blossoms that are dotted with purple spots. They are in bloom from July to September. Catnip flower is about 1/2 inch long and has 5 petals united into a 2-lipped tube. The upper lip consists of 2 lobes while the lower lip has 3-lobes which is common in mint plant family.

Catnip flowers form a dense whorled cluster at the ends of stems and branches. The fruit is not ornamentally significant. The names catnip and catmint are gotten from the intense attraction most cats have towards them and many people grow the plant just to amuse their cats. Young leaves are edible raw. They have an aromatic mint-like flavor eaten in salads.

Catnip also holds amazing benefits for human beings and is a very potent mosquito repellent.

How to care and grow Nepeta cataria (Catnip)?


It prefers to be in full sun but can tolerate some partial shade. Keep your plant at least 5 hours of direct sunlight daily.


It grows well in any good, fast-draining potting soil. It prefers the soil pH range between 6.1 (mildly acidic) and 7.8 (mildly alkaline).


Nepeta cataria prefers temperatures of 60°F to 70°F for best germination.


Water young Catnip plants twice a week for the first two weeks, reduce watering to every other week after plants become well established. Allow soil to go almost dry between watering. Keep the soil moist but never soggy.


Fertilize Nepeta cataria (Catnip) plants with a weak liquid fertilizer every two weeks. Start fertilizing the soil two weeks after planting and continue until the first week of the summer season.


It can be easily propagated by seed, stem cuttings, or rootball division. Cuttings from young plants tend to root more quickly, often in just a week. Stem cuttings should be about 4 inches long. Plant seeds in the spring and seeds germinate in 5 to 10 days. You can collect seeds from flowers, but the plant will self-sow and grow in the same spot year after year.


Prune after the first bloom to encourage a second flowering before the winter season. Chop the catmint plants down to 3 or 4 inches after the first frost. This helps encourage new healthy growth during the spring. Remove spent flowers by pinching them off to prevent self-seeding.


Harvest leaves at any time after the plant has reached 8 inches in height. Cut back but leave at least four inches from the ground to ensure regrowth. The best leaves will be those before the plant has flowered but it can be cut back several times during the year to retard flowering and increase leaf production. Dry leaves either by grouping stems together and hanging upside down in a dry warm place or by stripping from the stalks and drying on racks on in a dehydrator. Keep out of the sun to avoid bleaching of the leaves. Store in tightly closed jars or plastic packs.
