Hornbeams are a fabulous tree for bonsai, a firm favourite with many and for good reason. You can see from the impressive image above that they can be of majestic proportions and this is one of our members trees which he has had for many years and developed it into this fine specimen.
Hornbeam (Carpinus) are from the family Corylaceae along with Corylus, Ostyra and Ostryopsis. They are fast growing and easily grown trees with a very beautiful habit and form. They develop very graceful fine twigs, which makes them ideal as bonsai trees and you can achieve excellent ramification with them. They have hop like fruits and small inconspicuous flowers, catkins which are wind pollinated and a distinctive whitish bark which develops fluting with age. The buds are smaller than Beech but a similar cigar shape but tend to be more flat than rounded and green to red in colour. They are very hardy trees with a very dense wood properties and have a good longevity but winter protection is advised if kept as bonsai. Their foliage is vibrant and emerges in spring as a light green flush and then turns into a deep green.
