Advertisement What we have here is a variety of the Jackfruit tree, Artocarpus, being attacked by a relative, the Strangler Fig. However, this Jackfruit is antisocial. The sap is mildly toxic to other plants and can even be used as a mild herbicide. It also lays a great mass of hair roots out just under the surface of the soil, robbing the soil of nutrients so close competitors can't grow. Here a Strangler Fig has attempted to attack it but has been unable to embrace and crush the host trunk. Thus the long root/trunks surrounding the host tree.
