Purple bell vine is a delicate looking but vigorous vine that thrives in sheltered spot in the border or in a container with a trellis to climb, where the showy blossoms and long lasting calyxes can be appreciated up close. Pinch when setting out to develop branching growth and more flowering. Overwinter indoors if desired, bringing in when night temperatures are in the low 40's. Site in a sunny, south-facing window.
