Ooh, yes the flowers are very like skullcap, in that they all grow facing one side of the stem. Nice one, Heather!
The skullcap(s?) that are used medicinally don't seem to have the knotted
roots, though.
I was looking a bit at the Stachys genus, as well, since crosnes and Florida betony are both Stachys. I haven't seen any that are particularly like my plant yet, though.
