Kirk - I love the foliage. I think (not an expert here), that it needs to get in a bucket at least half filled with water - I do use preservative and attempt (don't always make it) to strip the bottom third of leaves. It stays in the cooler very well! When it wilts, its usually because I didn't get it in the water right away. It usually lasts quite well. I pick it when its mature, even when its formed the seed heads! Keep trying!

I never could get it to last either. But oregano and spearmint hold up very nicely. I'll have to give lemon balm another shot.
