My rating, on individual plants, varies from 1 to 5, depending on the cultivar. Some of the older varieties are so plagued with mildew that they are not worth having; some recent cultivars show promise. I have got several new ones and I shall keep or remove them depending on performance.

I have grown one kind of bee balm in a pot on my deck surrounded by other herb plants. I found that it was happiest when the pot was in a saucer of water. During the heat of summer (and this location on the deck) it flowered with large, long-lasting bright red flowers for about a month.
Does anyone know which part of the plant is used for flavouring the tea known by some as Earl Grey?
