Both bees and humans find this plant irresistibly attractive. In fact its Latin name Melissa refers to “bees” — these insects will flock to it whenever it is in bloom.
Lemon balm is originally from southern Europe but is now widely cultivated around the world. Like many mint family plants it is a very prolific grower. If you have limited garden space, you may want to place it in a container so that it does not take over the whole garden. (However, I don’t think that that would be such a terrible thing if it did happen...)
