Hari's herbs

Our friend Hari stopped by this evening with a cornucopia of fresh herbs and vegetables that he's been growing in his backyard. The amazingly fragrant mint, the lemon grass, chives, cilantro are currently flavoring the air - and I'm still trying to figure out what two bunches are. One has a distinct lemony smell, the other is extremely curry-like, but certainly aren't curry leaves. Thanks to eHow, I'm trying out some creative ways to keep these flavors alive. Any insights on what you've done with your fresh herbs are welcome!
