Thanks aswhad. You may be correct but it lacks the red in the stems and leaf veins. Also mine is far from fast growing as it is at least 10 years old.

Did you buy it or raise it yourself? Perhaps some Ficus? If it is some kind of Bonsai you could try at the Bonzai forum.

It looks like some tree/shrub to me

Thanks linaria! Must have bought it about 9-10 years ago, planted in a flower bed and after discovering caudiciforms a few years later I dug it up and potted it. I will try the Bonzia forum.
Thanks,
Bobby
