It's a big flower, with a little name.
The lady who lived here previously planted lots of lovely things I am/was not been familiar with. And most days I still have no idea what's what. The best I've heard to describe this kind of dilemma lately is a friend who stated, she often plays "plant or weed" w/another good natured, neighboring friend.
I uprooted a big, tall ornamental grass (unknowingly) yet cultivated nightshade for it's purple flowers - seriously - ?
