Mountain Ash - rectangle618 - 12-19-2017
The mountain ash in the back yard lost a limb to high winds recently. Today I cut the branch up and was surprised to see that the heartwood was very dark, as dark as walnut. I'm going to air dry some pieces, it's small but there's enough for some knife scales.
Couldn't find anything online about the qualities of American mountain ash wood. (Plenty about Australian mountain ash which is in the eucalyptus family and not the same tree.) Anyone have any experience using mountain ash? The tree is on it's last legs and will have to come down in the next couple of years.

I don't know.... However I have one plank of red oak that is unusually dark in color as well. Would like to hear more as the responses come in.

Mountain Ash is a pretty tree, liked by wildlife and gardeners. Not a large growing tree, although one up the block is at least 20 years old and about 40' tall. What I found:
WOOD PRODUCTS VALUE :
The wood of American mountain-ash is light, soft, weak, and close
grained. The heartwood is pale brown; the sapwood is thick and lighter
in color [39]. The wood is not commercially important [21].

You can always challenge commercial interests and try using it for something. I have messed around with Rhododendron as diversion from heavy pruning.

Well, there's this: "The American Mountain Ash was believed by American settlers in the 18th century to be powerful in exorcising witches..."

I am familiar with two mountain ashes here in Eastern United States. Mountain ashes are not ashes but are members of the genus Sorbus, in the Rose family.
American mountain ash, Sorbus americana is a small tree growing on rocky ridge tops and in bogs in the mountains from Georgia to Maine. it is shown as growing in one Illinois county, Ogle, by the USDA. The trees tend to be under 8 inches in diameter and the wood is dark, soft and weak.
It is more likely that you have European mountain ash, Sorbus acuparia, which is widely planted as a yard tree because of its bright berries which persist into winter. Apparently the wood is considerably harder.
In France, another sorb, Sorbus domestica, is quite hard and has been used for making planes. They call it Cormier.

Thanks for that, Warren. You're probably right about my tree being the European, Sorbus aucuparia. I planted the thing over 20 years ago, so it's not a native. Good news on the wood being harder. When it comes down, I'll investigate further.
