The bmp (deleted, seems to affect post) (307k) is a plant that grows along
the Root River trail in SE Minnesota. Email me and I will send you the
picture. I have seen it in only one place on the trail, it grows about 10
feet tall.
It covered about 150 yards. I suspect it was planted but am not sure.
The blooms are very fragrant and attract a lot of bees.
The Heart shaped leaves are about 8 inches long or more. The flowers are
white.
I would like to know what this is.
