I was reading that Jama Rosa is a somewhat cold-hardy variety of lemon grass. I wondered if that's what I used to grow. I mostly just kept my lemon grass outside in the ground...until the winter before last. Where I live, it's not so cold. But then it didn't survive that big cold spell. I need to find a replacement...maybe this weekend...I'm going to a big gardening event. I DO like lemon grass.
