I have seen a couple of plants offered here on the forum and a few more sold on eBay but none of those sellers included much information about it. One thing you should keep in mind when growing Eugenia noumeensis is that it is apparently from the New Caledonia Tropical Dry Forest ecoregion, the dry half of Grande Terre. It should be watered carefully, particularly as an indoor/greenhouse plant in temperate areas. It might be a plant sensitive to root rot from cooler temperatures and too much moisture in the soil. Similar issues have been encountered by growers trying to grow species from Brazil's Caatinga and Cerrado regions. But, there just is not a lot of information to go on regarding Eugenia noumeensis.
