If you count the golden rod along with the sea Myrtle and American beautyberry those are my favorite three species. Not sure which species that is but maybe it's the tall golden rod "Solidago altissima".

Hi, MunSung. Thank you! I've never gotten around to positively identifying the goldenrod but I think you're right about S, altissima. It's over seven feet tall. But, it appears that there are several different varieties growing in close proximity. I'm just not sure! Hopefully I'll figure it out one of these days.
