The sweet taste of a dead man’s finger

For the IncrEdibles festival Kew’s resident seed specialist Wolfgang Stuppy is contributing bite-size features about weird and wonderful edible plants from around the world. In the third of the series – the dead man's finger!

If you get excited by exotic fruits, here’s one that adds a little ‘creep factor’ to the experience. It belongs to an Asian shrub called Decaisnea insignis.

  • Freaky blue fruit The freaky fruit of Decaisnea insignis is kind of a secret delicacy. It’s been enjoyed for centuries by the Lepcha, the indigenous people of Sikkim, but outside its natural range (China, Nepal, Sikkim, Bhutan, and Myanmar) the dead man’s finger is little known for its edible fruits.

  • Like a cold human finger About 7-12 cm long, soft to the touch and covered in an eerily skin-like peel, the fruit of Decaisnea does really feel like a cold human finger, hence it’s common name ‘dead man’s finger’.
  • The taste of a dead man’s finger The weird fruits easily split along a straight line to reveal their translucent gelatinous pulp into which a large number of flat black seeds are embedded. The jelly-like pulp is the edible part, not the hard seeds. It’s flavour is very pleasant and subtle, mainly sweet, perhaps with a hint of melon or cucumber.

Danger! Don’t just eat any dead man’s finger!

Just to avoid any potentially dangerous confusion, it must be said that there are other species, unrelated and not all plants, commonly known as Dead Man’s (or Dead Men’s) Fingers, one of them deadly poisonous. Oenanthe crocata, a member of the carrot family (Apiaceae), is known under the common name ‘Hemlock Water-Dropwort’, but is also sometimes called ‘Dead Men’s Fingers’ (on account of the shape of its tubers). All parts of this plant are poisonous and occasionally lead to fatalities. Looking similar to Cow Parsley (Anthriscus sylvestris) or Common Hogweed (Heracleum sphondylium), it should be hard to confuse Oenanthe crocata with Decaisnea insignis. However, since Oenanthe crocata is deemed one of the most poisonous plants in Britain, a word of warning seems appropriate here. After all, as my colleage Steve Davis pointed out, in recent years Kew has received frequent enquiries concerning Oenanthe crocata, including a case of someone being admitted to A&E, and several cases of livestock or pet poisonings. Other ‘Dead Man’s Fingers’ are Xylaria polymorpha (a fungus), Alcyonium digitatum (a species of soft coral) and Codium fragile (a seaweed).
