How old is Rocky? Kittens almost never react to it, most cats develop an affinity for it between 6 months and a year.

Here's some info from Hunter Pet on catnip plants and here is a

Here is info from another site with more hints for growing it.

Good luck!

Note: it's estimated that 15 - 33% of all cats never develop a fondness for catnip. It's thought to be a genetic thing. Female cats are slightly more likely to be catnip-indifferent. (But I don't remember where I learned that: Cat Fancy, maybe?)
