Tree of Heaven
T’iis Nattói

Red and green samara with seeds visible inside them.

Tree of heaven is found in middle elevations growing at the roadside and in nearby swales. It is generally an unwanted interloper. It has pinnately compound leaves which are coarsely dentate. Portions of the tree take on a reddish hue by mid-summer because the samaras become partially red in color. The winter twigs are very thick and light brown, with a light brown pith. There are around 8 or 9 bundle scars in the leaf scars. The buds are hemispheric.
