The hornbeam bonsai, with their showy fall color, alternating leaves and interesting 'flowers,' make great subjects.
They are deciduous. By their nature, they grow straight. Therefore, the styles best suited for them as bonsai are usually formal and informal upright.
The European hornbeam (Carpinus betulus), Japanese (Carpinus japonica) and American (Carpinus caroliniana) are all popular as bonsai.
Overall the Carpinus genus has approximately 25-30 species. So it shouldn't be surprising to find many good hornbeam bonsai around most all of the world's temperate zones.
The wood of the Caprinus is very hard (was used for structural beams) and almost white, which resembles animal horns (which were used for knife and utensil handles etc.) Hence, "horn" "beam."

As with any bonsai, people often ask "Do they bloom?"
The answer is "yes, however ..." Carpinus does not have what you may think of as flowers, it has catkins.
"Catkins - Elongated cluster of single-sex flowers bearing scaly bracts and usually lacking petals.
"Many trees bear catkins, including willows, birches, and oaks.
"Wind carries pollen from male to female catkins or from male
catkins to female flowers that take a different form (e.g., in spikes). " Source - EncyclopediaBritannica.com
The catkins vary greatly among the 30–40 species.
