Despite the beautiful, tiny flowers appearing in clusters of up to 10 per leaf axil I heavily disadvice growing this plant in open soil/gardens.
One of the very few Aristolochia capable of becoming troublesome weeds, this plant will spread quickly underground by means of the fleshy, rhizomatose roots.
If broken, a new plant will emerge from each fragment the next season so the best way to control this species surely is planting it in a container.
