Physostegia virginiana.

I have some in my garden, and it does spread! I bought it in a
small pot from a nursery, because I was intrigued by the fact that the
tiny trumpets can be swivelled round the stem to a certain extent and
remain at the angle it was placed. Hence the "obedient plant". :-)

Damn! Now I've de-lurked I must introduce myself elsewhere!

Hello Gordon

Hi Anne! I expect to pick up more info than I "propagate" on this
knowledgeable group. :-)
