Western Soapberry
Clusters of amber soapberries glow like marbles after the leaves fall, making this modest plains tree easiest to recognize in winter.

The fruit contains saponins that foam in water, explaining the name, but it should not be treated as an edible berry. Compound leaves and smooth gray bark accompany rounded crowns that often expand into colonies through root sprouts.
Look along warm draws and old fencerows after frost, when persistent fruit catches low sunlight. Photograph rather than taste, and distinguish it from chinaberry by the unbranched leaf arrangement and smaller translucent fruits.
