About This Plant

Decaisnea fargesii, also known as the Blue Bean Shrub or Dead Man’s Fingers, is a deciduous shrub from China. It features pinnately compound leaves and inconspicuous greenish-yellow flowers in late spring to early summer. What sets it apart are its unique blue, finger-shaped fruits that ripen in late summer to early autumn. These gelatinous, sweet-tasting fruits are edible but are primarily valued for their ornamental and curiosity-inducing qualities in gardens and landscapes.

The Story


The Decaisnea fargesii features pinnate leaves with an attractive blue-green hue. Each leaflet is lance-shaped and measures approximately 10 to 15 centimetres in length, contributing to the overall grace of the compound leaves.


The Decaisnea fargesii produces large, elongated fruits that resemble sausages or beans, typically measuring around 6 to 8 inches (15 to 20 centimetres) in length and 1 inch (2.5 centimetres) in diameter. These unique fruits have a smooth, bluish-green skin, and when mature, they reveal a gelatinous, seed-filled interior. The seeds are embedded in a translucent, mucilaginous pulp.
