Introducing the Carpinus japonica Japanese Hornbeam, a stunning addition to any garden, originally found in Japan but now cultivated as an ornamental tree elsewhere. Standing at 12-15m tall, it boasts dark glossy leaves that are longer and darker than the European Hornbeam. The foliage is flat-topped when mature, and the striking green catkins turn brown over time. The autumnal leaves also turn an appealing shade of red. With 20-24 pairs of parallel sunken veins and whisker-tipped teeth every third tooth, this tree is known for its visual interest. With a Royal Horticultural Society Award of Garden Merit, this tree is a must-have for lovers of unique, eye-catching plants.
