Buckthorn is a deciduous shrub or small tree (up to 8 m) with a rounded crown. As the name suggests, it often grows along roads, ie forest. During our walks we usually look at the more prominent plants such as trees, but the bushes along our path we usually pay not much attention. Spork Wood and buckthorn are so prevalent in our country, it’s worth it to learn more about it.
Buckthorn is usually larger than buckthorn. The branches often end in takdorens. The buds have a clear, brownish purple with knopschub gefransde edges. The leaves are oval and focused with a fine serrated edges. They are 4 -7 inches long. The three to five pairs veins are curved. The blade tip is often slightly twisted.
Buckthorn blooms in late May, early June. The flowers are greenish-yellow foursomes, free discreet and smell unpleasant. Buckthorn often dioecious, meaning they only carry male or female flowers.
The round stone fruits are big and peas contain 2-4 seeds. They are blue-black when ripe and juicy. The unripe berries are poisonous.
The bark of the trunks and older branches is gray-brown, furrowed cork, and dotted with many pores.
Buckthorn is almost everywhere in Europe except in northern Scandinavia.
He is also found in North America, where in some areas a real invasion of buckthorn has taken place.
It grows preferably on calcareous sand – and peat.
In the Netherlands, buckthorn quite rare. We think including him in calcareous dunes, the Achterhoek, South Limburg. In small quantities it grows in stream valleys of central Brabant and Drenthe. He is an important part of the dune thickets in South Holland. There he formed a plant community with wild rose, barberry, hawthorn, wild-rose and spindle tree.
The Latin word was then for several gedoornde Rhamnus shrubs. Catharticus purgative means, ie, bowel cleansing.
The wood is pale red-brown sapwood around a nucleus. It is hard and tough and a cross section showing the structure flamed. It is suitable for small cuts – and turning.
