Fagus sylvatica Interrupta

Fagus sylvatica 'Interrupta' is a form of Common Beech with very unique green leaves, often very deformed, with a more or less divided leaf. Lobed and irregularly "broken," many leaves have a lobed leaf section followed by a section consisting only of the central vein of the leaf, and then another lobed leaf section. This medium-sized, compact tree develops a rounded, closed, and dense crown. This very rare variety should be highlighted as a standalone specimen. It requires a soil rich in humus.

The beech, in Latin Fagus sylvatica, is an imposing tree with a spreading habit. Its cylindrical trunk is covered with smooth, light grey bark. This tree can live for several centuries. Native to central Europe to the Caucasus, it is one of the most common species in European forests. Its reddish wood is used in cabinetmaking and for the production of wooden tools and toys as well as firewood. It is very hardy and can reach a height of 20 m at maturity.

'Interrupta' comes from the cultivar 'Rohanii'. It was created at the Trompenburg Arboretum in Rotterdam, the Netherlands. This species is compact, has slow growth, and a rounded crown. It reaches a height of 10 to 12 m at maturity. Its leaves are irregularly cut and deformed. They measure 4 to 7 cm in length. The flowers appear almost at the same time as the leaves. From April to May, barely visible, cream-coloured monoecious flowers appear. The male flowers are grouped in pendulous catkins of 40 to 60 mm. The female flowers are grouped in 2 to 4 at the end of the branches. Mature specimens produce fruits called beech nuts, which are shiny brown and covered with bristly prickles. These 12 to 18 mm long fruits are edible in small quantities. Mountain dwellers used to use them to make flour.

Fagus sylvatica 'Interrupta' is a very hardy, low-maintenance tree. It likes partial shade and non-scorching sun and prefers cool and temperate climates. The soil should be moist and well-drained and always have a constant moisture level as it does not tolerate drought. Planted as a standalone specimen, it has an elegant presence and is regularly observed to admire its always surprising leaves. It is suitable for medium to large gardens.
