I have not grown this plant which is native to the following areas: Argentina, Brazil and Paraguay. It has naturalized in Hawai'i being found only in the Kailua Gulch area of east Maui. It can be found found along the Hana Highway on steep rock gulch walls near the road as well as in disturbed sites near the road. It is listed as a noxious weed. Solanum robustum is grown in botanical gardens. It is cultivated because of its attractive leaves and winged petioles. The above Information is from the plant's description by Forest and Kim Starr and Lloyd Loope, HawaiianEcosystems at Risk project (HEAR).
