Boxelder, ash maple burl
11.11.2024
The ash-leaved maple Acer Negundo came to Europe from North America around 1690, and it seems to feel very much at home here; the tree is widespread. The leaf shape, which is rather unusual for maple trees and is reminiscent of ash leaves, gave this tree its name ash-leaved maple. Its wood is very light-colored and medium-hard, and it is particularly interesting that these trees very often develop burl growth trunks; this more frequent occurrence appears to be a genetic predisposition. While it is rather rare in other trees, burl stems are more common in ash maples, unfortunately usually only at an advanced age, and this development is usually accompanied by a degradation of the wood substance inside the trunk. There is a very impressive 100-year-old ash maple near Berlin, which has a diameter of well over a meter, the inside of the trunk is completely hollowed out, and the trunk, which sprouts again every year, actually consists only of the burl wood under the bark. You can find a few photos of this natural monument in the gallery.
The special feature of ash maple burl is a unique, often fiery red color inside the trunk. This discoloration occurs as the tree tries to defend itself against invading fungi and produces these unusual colors, which can be clearly seen with lines of defense of the healthy wood against fungi and other wood-destroying parasites. In the case of the tree from which these beautiful pieces of burl wood comes, it was as often can be seen: the entire trunk was completely decomposed on the center, only a 15 - 20 cm thick layer of the finest burl wood supported the whole tree, and as a result of a storm this old tree then fell this year.
We were the lucky beneficiaries of this tree fall, the particularly beautiful burl wood is now drying in our warehouses and will probably be dry enough next year to be available in our webshop.
