Decaisnea fargesii is commonly known as dead man’s fingers or the blue bean tree. This shrub is native to western China and other western Asia countries such as Nepal, Bhutan, and northeastern parts of India, though its common names originate from Ireland. This shrub is often as wide as it is tall, growing to 4 m by 4 m. It commonly flowers in the summer while its fruit ripen in the fall. This plant is distinctive for its blue sausage-shaped fruit, which give its various common names. Although the fruit is edible, the tree mostly serves an ornamental or decorative purpose when grown in non-native parts of the world.
