There are no reports about this species becoming a weed. However, once established it is very difficult to eradicate, spreading by stolons for up to 2 metres a year in the wet tropics and about 1 metres a year in the subtropics. Since the seed develops underground any natural dissemination can only be by water erosion. The seeds are soft and digestible and are not spread through animals[

Propagation

Seed - when fresh it has a high level of dormancy, which may be reduced by drying the seed at 35 - 40°c for 10 days. When growing the plant in new areas, the seed should be inoculated with a specific strain of Bradyrhizobium, which is different from that used on commercial groundnuts. Sow the seed in situ - a well-prepared seed-bed is desirable but not essential. The seed should be sown 2 - 6cm deep at a rate of 10 - 15 kilos of seed per hectare, followed by rolling[
