Gosh, I had to edit this to add Welcome To ATP! I thought I might know the answer, so I just answered. But Welcome!
I think she might be referring to this plant:
I grew this for a time when I lived in Austin, but it was in a confined space and couldn't escape from where I had it growing. It's considered invasive in places. I loved it and would grow it again if I came across it. It's the sort of plant you need to know about before you grow it. Depending on where you live you might need to be take precautions to ensure you were in complete control so it didn't invade somewhere else successfully.
