Does your water mint have good flavor? I haven't grown it before, but the stuff I've seen and tasted didn't have much more flavor than our lawn. If yours tastes good, go for it! mmmmm mojitos!

More ideas if the mint is tasty:
Make sun tea or dry it for use in winter teas. Mint with cucumber and plain yogurt makes a great sauce for spicy meats and curries. Mint jelly is a good way to preserve lots of mint, if you like it- it tastes great with lamb. You can make a terrific salad with equal parts chopped mint, cooked and cooled grain like quinoa or bulgar wheat, and other minced fresh vegies like carrots, cucumbers, tomatoes, parsley, toss with a bit of lemon juice and olive oil and snack away!

I'm curious about your water mint because if it has good flavor, it may be something I haven't seen before.

I guess that was my question - is it edible and does it taste good. I haven't tasted it. I was hoping someone knew. I'll taste it this weekend and let you know.

Well, I finally got up the nerve to taste it. It does taste minty but it's not a good tasting mint, if that makes any sense.
