My friend Sandra, whose blog I follow, gave me a little lemon balm plant.
I took the plant stake out of the Monarda, which no longer needs it as a "don't mow over me" protector. The stake is about 20" high, so we'll see what kind of progress the lemon balm makes come Spring. That is, if it survives the winter. I have every reason to believe it will; the mint family is tough.
