Some Brachychiton (bottle trees) have similar leaves. There are hybrids offered, so I am not certain at this young age, and sans a flower photo, of a more specific id. Sometimes the leaves change form as the plant matures. I am more familiar with Brachychiton when they are mature.

Or maybe someone has a completely different id idea.

Maybe a jatropha mahafalensis? The thick trunk is, if either gyr or I is close, a Caudex: these plants are caudiciforms and can retain great amounts of water in a thickened trunk during dry spells of all-the-time where they're from. Where are you? SoCal or outside the U.S.?

Macranthos, your id seems more logical. Knowing the location really helps with id. I always forget that jatropha because only other species, with completely different foliage, are sold here.

I am outside US in Kathmandu, Nepal. I found this plant in a local Nursery but they have no idea about it. I was told they got it from a guy who germinated it from seed
