Wollastonia biflora is a moderately salt-tolerant plant found in the tropical belt of the Indo-Pacific region, including China, the Indian Subcontinent, Southeast Asia, Queensland, and islands of the Pacific such as Fiji, Niue, Tonga, Samoa and the Cook Islands.

It is found commonly in islands and in coastal areas, although it sometimes occurs inland in neglected and unmanaged plantations as well as in ruderal environments.

[4] Together with Portulaca oleracea, Ipomoea pes-caprae and Digitaria ciliaris, Wollastonia biflora is usually one of the first species colonizing degraded or altered environments in tropical zones of the planet.

[5] Wollastonia biflora is a hardy and somewhat woody, sprawling perennial herb or subshrub.

[9][10] Wollastonia biflora has traditionally been used as a medicinal plant in many cultures, including in Marovo in the Solomon Islands.
