Purple bell vine grows best in a warm, sunny or lightly shaded spot with free-draining soil, and it’s usually planted out after frost or grown in containers that can be sheltered. Plant it at the same depth as it was in its pot and provide a trellis, obelisk or netting straight away, as it climbs quickly. Keep the soil evenly moist but not soggy, feeding every couple of weeks with a balanced liquid fertiliser once it starts to grow strongly.

Remove faded flowers to keep it blooming and pinch back any overly long or tangled stems to encourage a fuller plant. In cooler areas, treat it as a tender annual, but container plants can be overwintered under cover in a bright, frost-free place with reduced watering.
