It is perhaps better known in Hawaii, where it is an introduced species and an aggressive invasive weed with rapid negative effects on local ecosystems.
The fruit is a capsule about 1.2 cm long containing yellowish pulp and a single black seed half-sheathed in a bright red aril.
A laboratory study confirmed that extracts of the plant had antimicrobial action against the human pathogens Escherichia coli, Staphylococcus aureus, and Pseudomonas aeruginosa, as well as Bacillus subtilis.
At one spot on Hawaii it moved from the local landscaping and soon covered over 3500 acres of abandoned agricultural fields.
[1] It easily invades eucalyptus plantations and areas of forest already dominated by non-native trees and shrubs.
