We did some research and the myrtle family (Myrtaceae) contains about 150 genera and 3,300 species of trees and shrubs. You can search for "Eugenia" or "myrtle" to check if it is similar. We can update our plant database and could you please tell us more details about your plants, for example, the botanical name of your plants. Please let us know if you are referring to "Metrosideros excelsa".
Thanks for your confirmation and we will send you email to notify you when we update our plant database in a few days.
