We haven’t succeeded in growing catnip, but we got a big jar at Petsmart, and Jake says it still smells good. Sometimes I have to catch myself before I put it in soup, instead of oregano.
Stuff grows like crazy around here. It should grow down south where you are.. I don't have any seed (or if there is any left on the plants it's not much..) cause I never had to plant any, but I could take a look and if I can scrounge up enough to bother I could accidentally mail you some (so that the USPS drug-sniffing cat will 'alert' on the envelope... ;-)

Well, it it's oregano flavor you want, best grab the oregano. But using catnip might just start a new seasoning fad... I'm sure it wouldn't hurt (other than NOT tasting like oregano.)
Methinks I read/heard somewhere about catnip tea having some value - not sure what it would taste like though... ;-)
