That's Bee Balm, right? Mine hasn't bloomed yet, but it's getting close. I had to replant this year. I lost a huge plant from this years winter harshness. I hear there is a purple cultivar out there, but mine has always been red. This year mine is strongly scented of minty sage. Much stronger than the one I had before.
Sometimes I steep them with chamomile tea or on their own. They are said to help with sleep issues. I've not used them in a satchel.
I've enjoyed it on fruit salads before, but this one I think is more savory.
