The majestic Caucasian Walnut or Pterocarya fraxinifolia attracts the eye with its surprising and highly decorative fruiting: in summer, it is adorned with hanging spikes 30 to 50 cm long, covered with small green winged nuts 2 cm long, which are sure to attract attention. Introduced into France in 1784 (and the United Kingdom in 1800), this beautiful tree also knows how to be useful: planted at the edge of watercourses, it helps to maintain the banks.
Native to Iran, the Caucasian Walnut can withstand cold temperatures down to -20°C. When fully grown, it reaches a height of 20 or even 25 metres and a spread of 15 to 20 metres. This tree has a rounded, spreading habit and very long deciduous leaves. Each leaf consists of about 30 serrated leaflets, 30 to 40 cm long, of a shiny dark green colour. In autumn, they turn a beautiful yellow colour. The trunk of the Pterocarya fraxinifolia has very deep, winding grooves. The tree flowers in June. The tree then unfurls long garlands of beautiful yellow-green.
The Caucasian Walnut thrives in all types of soil, provided it is moist. Suitable for both sun and semi-shade, it is planted in autumn. It is pruned every year before the vegetation starts again, in order to remove dead wood, crossed branches and unwanted shoots.
