I wish to know scientific names of the plant photos attached. The first I beleive to be Eupatorium triplinervum-am I right? Thanks in advance.
It would help to know if these are wild and the location, but #1 looks like a [FONT=arial,sans-serif][SIZE=-1]Eupatorium. [/SIZE][/FONT][FONT=arial,sans-serif][SIZE=-1][/SIZE][/FONT][FONT=arial,sans-serif][SIZE=-1] [/SIZE][/FONT]
The second one is probably a scroph, but that doesn't narrow it down much. Or could be a mint like [FONT=arial,sans-serif][SIZE=-1]Physostegia[/SIZE][/FONT][FONT=arial,sans-serif][SIZE=-1], but probably not. [/SIZE][/FONT][FONT=arial,sans-serif][SIZE=-1]Can't tell much about the stem.[/SIZE][/FONT][FONT=arial,sans-serif][SIZE=-1] [/SIZE][/FONT]
Second is much more like Penstemon than Physostegia. Third: flower spikes and opposite leaves remind me of Citharexylum, though leaf shape and size different from the well known C. spinosum. But it's a large genus - and there are probably other genera of Verbenaceae a bit like this too.
