I grow M. 'Jacob Cline' and agree that it's unlikely that Fleemo is
seeing seedlings of the plant.

Well, I don't pretend to be a plant expert, but it *sure* looks like
Monarda to me, and is growing in the same area that my original
Monarda was growing.

Here are some photos for a positive ID:

As I recall, my monarda wasn't clumplike at all, but grew in
individual stalks, flowered, then perished completely. The next year,
seedlings like the ones pictured appeared in its place, but never
flowered. It is a pretty shady area, but I thought I'd read that
Jacob Cline did alright in semi-shade.
