Amaranthus 'Love Lies Bleeding'
A similar looking plant is Kiss-Me-Over-The-Garden-Gate (Persicaria Orientle). It can grow to twelve feet tall and two feet wide and can be planted in containers (although you would require a huge container to hold this height) or in borders. My photo was taken at the Chicago Botanic Garden last summer where it was planted in the ground with dahlias framing their entrance.
I have included my photo of inky fingers coleus crawling through my raised bed (this is just one plant). I had to go back into my 35mm prints to find these. It sure makes it a lot easier when everything is digital.
