Single-leaved Ash | Fraxinus excelsior ‘Diversifolia’
The group of ash trees here is special. In fact, they have only a single-leaf leaf and used to be literally called 'Monophylla'.
The ash tree occurs naturally, in various species, across much of Europe. However, Fraxinus excelsior ‘Diversifolia’ is the only species found in the Netherlands. Along with the privet and the lilac, the ash belongs to the olive family. The tree thrives in moist, nutrient-rich soil. Otherwise, it has few requirements. Ash trees come into leaf late in the spring and shed their leaves early in the autumn. This species is unusual: the tree has a single leaf composed of two smaller leaflets. This variation was discovered in England in 1789. In its early years, the tree is almost columnar in shape. Later, it develops a broad, upright crown that can reach a height of 15 to 18 metres. Its width is approximately 10 metres. The dark brown, almost black buds, which are clearly visible in winter, are particularly striking.
