it should be fine if you grow it in pot for the next 4-5 years, you can bring it inside, it grows quite fast but won't barely exceed your height by that time. You will also have to prune it so it grows new branches and not become to high. The more branches you got the more flowers you'll have. I ordered a new one but they don't deliver in winter, so I have to wait. My other one was like your picture, but died from cold.

This may be a Macadamia integrifolia X Macadamia tetraphylla (Variety Beaumont), they sell those here in Japan and they also have 2 leaves per whorl just like yours. The flowers are pink and it's a very good hybrid, fast growing it can bear in about 4 years.

Hi everyone,
I'm a graphic designer living in Japan.
I started growing tropical fruits about 20 years ago, by planting the seeds of every exotic fruits I could get my hands on, just wanted to see how the tree looks like and it soon became one of my main hobbies, the other are cinema and travel.
English is not my native language, but I'll try my best.
