Red flags: Unbelievable nature you've never seen before!, no external source cited, low image quality could be hiding AI artifacts, lacks scientific name for plant, OP is an aesthetic blog (no offense, I see you credit most of the artists you post, OP <3).

Green flags: Common name of the tree provided (although the leaves don't look like any olive tree I've ever seen).

Reverse image searches and citation trails all seem to lead back to now-deleted Reddit posts. Google Images says it's this one in r/NatureIsFuckingLit, and TinEye says it's this one in r/interestingasfuck. Both were posted back in 2020. This is important because the rise of AI images was in 2022.

People in the comments of places this image is posted throw around botanical terms like "dichotomous branching" [branches split into two at the nodes] and "divaricated" [branches grow far apart from each other], which are cool, but don't tell me what the tree is.

Searching up "Black Olive" on iNaturalist finally got me some answers, and it turns out that YES. This is a real tree! This tree is a Dwarf Black Olive (Terminalia molinetii, Formerly Bucida spinosa). The above photos are some particularly nicely framed shots of a tree with particularly small leaves, which really highlights the branching structure. I really wish we knew the photographer's name. Here are some more photos of the same species:

This tree is native to Southern Mexico, Belize, the southern tip of Florida, and Cuba. Dwarf Black Olives are completely unrelated to Olive trees in the Olea genus that I'm more familiar with (the former is in Order Myrtales [Myrtles, Evening Primroses, and Allies], and the latter is in Order Lamiales [Mints, Plantains, Olives, and Allies]).
