Lemon Balm is well-loved in the herbal world for its lemon-flavor as well as for its reputed health benefits of reducing anxiety, calming the mind, improving sleep, and improving cognitive functions. Gardeners may appreciate 'All Gold' Lemon Balm simply for its beautiful, fragrant chartreuse foliage that will brighten the shadiest garden spots. More sedate in its spreading that regular lemon balm, 'All Gold' can grow into a mound a bit over a foot tall and wide. Hardy to -30 degrees, this herb can be sheared back just before blooming to encourage regrowth. If you let the flowers open, bees will most likely appreciate it.
