This plant is very versatile in as much that it can be used at the back of the garden border, growing up to 9Ft high, it can also be used to very dramatic effect as a house plant, I plant a selected specimen, (this needs to be selected as some plants grow out horizontally before going up ),these are planted in a 10" clay pot and grown on until they form flower buds (in their second year),they are then brought inside and placed, usually in the fireplace (chimney bellflower ?), as the flowers form from the top of the stem they make a lovely much commented on display. Please try it, you will use them in subsequent year I am sure.
