I do not know where I got this plant but makes a nice bonsai candidate. Looks like Texas ebony but it is not. Someone told me it is Ostrya and none of the pictures looks like my plant. The branches and stems of this is quite hard and brittle. Even the tiniest branches that have hardened are hard to bend. So I have been just using clip/grow on this.

Smooth darkish bark and no thorns.I have not seen any flowers on this yet. Propagates from cuttings fairly easily.

Also I believe this is a tropical plant. It does well throughout the winter with some light. Does not need very bright light to survive the winter. In summer, I keep it in direct sunlight. Transitions from indoor to outdoor pretty easily too. No pest problem either with this. Let me know if you need any other info.

Here is a close-up of the leaves.
