Lemon Balm

Relaxing, refreshing, easy to grow. Makes an excellent tea. Mix with lemon aid and honey for an excellent summer afternoon treat. Rub a small handful of leaves between palms and toss in water bottle. Steep with chamomile and skullcap for a sedating nighttime sleep-aid.
Drought tolerant once established. Not picky about soils. Can become weedy, some people keep in pots or places where a barrier will keep roots from spreading.
