Hope it's alright that I'm linking to my Artstation gallery. This is a procedural mangrove tree I made with Blender geometry nodes. I've been working on it for a while, finally got it in a state where sets can be populated with it. The approach is pretty naive, there's no phototrophy or anything fancy (yet!), just branches planted on branches planted on branches... I did respect the golden angle though, and the leaves turn to face the sun to an extent. I'd like to try space colonization next, most likely that will have to be simulated from the seed onwards. But that should yield much more organic and realistic shapes.
