Texas ebony tree ( earlier formally called as Pithecellobium flexicaule, but now it is Ebenopsis ebano) is a slow grower. Because of this reason, Texas ebony is a good choice for small bonsai (shohin) or midsize bonsai (chuhin).
The tree has tiny evergreen compound leaves which are about 2 inches in length. During the night and early morning, the leaves of the tree fold central leaf stalk.
Texas ebony bonsai produces beautiful ‘Puffs-like’ flower spikes and persistent woody seedpods when it is placed outdoors. However, when grown as an indoor bonsai tree, these are rarely formed.
In areas of the trunk that are older, the bark appears grey-brown with some fissures and a rough surface.
Despite its natural tendency to do well in hot, dry climates, the tree has adapted to drop its leaves in times of drought and grow them back when water becomes available again after the drought has ended.
The branches of this plant grow in a distinctive zig-zag pattern. There are spines hidden under the foliage that need to be watched out for.
Because it is highly tolerant to indoor climate, it makes for an excellent indoor bonsai tree.
Hard and resistant, Texas Ebony wood is quite durable. Hence it is much suited for jin or deadwood designs.
The tree is suitable for all bonsai styles, except for cascade style as the wood of the tree is pretty hard.
When the bonsai is kept outdoors, it will produce flowers in late winter and early spring.

These seedpods are NOT produced when the tree is grown indoors.
Best location to keep Texas Ebony Bonsai
Texas ebony bonsai tree can grow in full sun as well as partial shade of a house.
Remember, the more light it receives, the better the growth of the bonsai tree.
When placing it indoors, keep it in a south or west facing window or windowsill.
One of the things which makes this tree a great choice for indoor bonsai is its nature of thriving in typical home temperatures: – 70°F to 80°F (21°C to 26°C).
If such temperatures are maintained throughout the year, the tree won’t even become dormant or need a resting period.
This tree is very hardy and can tolerate temperatures as low as 30°F (-1°C). But prolonged exposure to such temperatures will lead to the tree dropping its leaves.
You do not need to worry at this point, as the tree will regrow its leaves when the temperature becomes warmer again.
