lemon grass is a close relative of the citronella plant that is used to make citronella candles. Actually a lot of lemon scented herbs are mosquito deterrents like lemon thyme.
Aida......If you can't find it in a regular grocery store, maybe a chinese grocery would have some stalks?
Or ask your grocer if they would bring some in for you?? Just a thought.
Good Luck in your hunting, let us know if you find some.
I didn't find any this week either but I think I will at some point in time maybe on into the spring months. I will check at another grocery nearby as well. I'm eager to get them started.
