If you want to cover an area quickly thenis your plant. More often grown outside as an annual it will make a rampant perennial indoors. Climbing by means of tendrils it produces strange purple cup and saucer flowers in late summer. When it has finished it can be cut back hard to remove almost all the growth which becomes tatty by winter. Not only will it sprout again in spring but you will probably find it has seeded itself around. It will do better planted out in a border but can be confined to a pot. Seed sown early in the year must be fresh to germinate well.
