What is Catnip

Catnip (Nepeta cataria) is a flowering plants in the family Lamiaceae, the mints.

There are a number of varieties within the mints and Catnips.

Why is it Attractive to Cats?

This is a question that has not been absolutely answered yet!
This is what we know:

Nepetalactone is an organic compound, first isolated from the plant catnip (Nepeta cataria), which acts as a cat attractant.

Nepetalactone is bicyclic terpenoid, i.e., it is a ten-carbon compound derived from isoprene with two fused rings. The structure and the effects are similar to those of valepotriates.

Nepetalactone was first reported in 1941 after it was isolated by steam distillation of catnip.

Nepetalactone is also present in the wood of tartarian honeysuckle (Lonicera tatarica), shavings of which are often used in cat toys.

Can I Grow Catnip?

It is native to Europe & Asia, however has become naturalised in America & Canada after being introduced. There are approximately 250 species of Catnip, and this figure doesn't include hybrid species

Catnip is a hardy perennial that is easy to grow, if no one eats it out of the ground. Seedlings are available from garden stores herb sections. It is also easy to grow from seed. I often just throw some store bought catnip in the ground and there are enough seeds to provide catnip all season. It likes sun but will tolerage almost full shade.

To dry, just cut and hang out of reach of cats. When it's dry, place in a closed container or plastic bag and serve as required.

It is a common weed and once you know what it looks like it is easy to recognize. The smell is distinctive. Various varieties are more or less attractive to cats.

Are there Other Plants like Catnip?

Valerian, Silver Vine, Honeysuckle, are some plants that also attract cats. See my article about plants that cat like.

Catnip's chemical structure is similar to that of the valepotriates derived from the herb valerian (Valeriana officinalis) which also has a catnip-like effect on some cats

Catnip as a Bug Repellant

Iowa State University found that the nepetalactone in catnip is a mosquito repellant. It is more effective than DEET. Catnip probably does not last as long since it is volatile but catnip is not toxic.

It also repels termites and cockroaches.

Mice and Rats also seem to dislike the smell and it used to be planted to repel them. (Maybe it just attracts more cats!)

Actinidine, a compound found in valerian and silver vine, is a pheromone for a variety of insects. It is used for the biological control of some insects.

Human use of Catnip

Catnip leaf tea was a popular beverage and like chamomile tea, the catnip tea has a mild sedative effect on humans. The herb has been used as a remedy for colic, minor aches and pains in the gums and teeth, indigestion, and as a help to sleep. Valerian is often also used to calm and help sleep. It had many uses in the early days and catnip escapees from the North American European settlers garden adapted and thrive now wild.
