We’ve been growing bee balm (or wild bergamot, or monarda) for many years. It started as one large clump, and then we divided it into two sections. Each year it’s been the same pale purple color.

Last year there were a couple of volunteer blossoms, but this summer new growth is popping up all over. The first new plants were purple, too, but then I noticed a pink flower…

…which turned into a pink patch.

Later I found a nearly white patch, then several more clusters like this.

And finally, I found a couple of blossoms that were a darker purple.

Those are all the color possibilities that minnesotawildflowers.info lists for bee balm, all right in our own front yard.
