The staghorn sumac (Rhus typhina) is actually more like a bush, than a tree.
Its wood is rather light and soft - rather brittle. It can be carved very well. It is very decorative because of its color.
The wood has a very light, almost white sapwood. The core is striped green, a very very decorative clearly visible grain that makes the wood very popular especially for wood turners and other artists.
It is said that the wood had floureszent properties, it is highly luminous neon yellow under UV light. Sorry but I could not yet check this by myself.
In general, all parts of the plant are considered to be slightly toxic. You should wear a dust mask when working with it, especialyy while sawing and sanding. Even the wood should not be used for children's toys.
