The most unusual plant in town. No... really it it.
If you have a nice bright sunny spot and can water a plant every 7-10 days, well... you might want to come scoop this up. Lowes, Home Depot, and whatever else isn't going to have these. They take quite a bit of time to turn into larger trees, but with some patience you will have yourself a pretty rad tree.
This plant originates from Madagascar! It's a succulent that is related to cashews, mangos, and pistachios.
All of the below images are examples of what the plant can become. The specimens I have in the shop are smaller for sure. But they grow lots during the spring-fall. One of my friends has one she got in early summer. "out of control" is how she describes it's growth. In that good out of control way.
Do you even Bonsai Bro? Operculicarya are excellent bonsai specimens. You can trim and shape to your hearts desire.
Want to just let it go? It will for sure go. Lots of lateral branching for this plant. Wild and crazy or perfect little trimmed tree? That's on you. One really cool thing you can do with this plant is to raise/expose some of the trunk that is below the soil every couple years. This will start to expose the knobby bulbous root.
My greenhouse was able to get me some at a pretty good price, so the ones I have in stock are only $6. They are in 4"diameter plastic grow pots at the moment. I can get larger ones for sure, 3' to 6' even. But those are gonna run quite a bit more.
a pretty quick google search will get you to "how to bonsai Operculicarya" So have fun folks.
