Where do they sell trays of wheatgrass already grown? I can't find them at my local florists.?

I like the idea of wheatgrass grown as a decorative accent. It's usually in a tray. I can't seem to find it at any local florist. Hope someone can help

I would try a good health food store. If you have a Whole Foods in your area I would try them. There's also places online.
Reply:Some larger health food stores or "natural grocery stores" carry it.
