Dead Man's Fingers, Decaisnea fargesii

Decaisnea fargesii: True Ghoul Blue

There are three Dead Man’s Fingers: A seaweed, a mushroom, and a shrub, all so-called because of the way they look.

Young Decaisnea fargesii

The seaweed, covered elsewhere on this site is Codium fragile. Soft and velvety, it floats eerily like a hand, and is edible, as are most seaweed. The mushroom, Xylaria polymorpha, like most mushrooms, is not edible. When young it not only looks like fingers reaching out of the ground but it even has fingernail-like tips. The third Dead Man’s Fingers is Decaisnea fargesii, an up and coming and escaping ornamental shrub.

This is a frost-hardy shrub that likes cooler weather and is native to the Himalayas and Western China where it can be found from 6,000 to 10,000 feet. In the United States it is found in zones 6 to 10, or down to about -10° F. You can find it in landscaping in such diverse locales as Kentucky and Ohio to Oregon and Washington. It is also escaping into the wild. It’s main calling as an ornamental is that it has blue, edible, fruit.  Other than the fruit, to a North American eye the shrub resembles a small black walnut

Dead Man's Digits

Whether there are one or two species of Desaisnea is a bit of a debate. Some say the D. fargesii is from China with the blue fruit, and others say there is a Decaisnea insignis from Inida with yellowish fruit. The Chinese one, D. fargesii, is the most commonly cultivated and thus escaped into the countryside.  Oddly, it is in the chocolate vine family, Lardizabalaceae. The fruit’s white, juicy phlegm-like pulp, ranges from bland to very sweet. The watermelon-like seeds are not eaten.

The genus name is no help at all in identification. Decaisnea ( deh-KANE-ee-uh) is named for Joseph Decaisne, a 19th century Belgian-born French botanist, horticulturist, and director of the Jardin des Plantes Paris. The species fargesii (far-GHEE-zee-eye) was “discovered” and named for Pere Paul Guillaume Farges (1844-1912) a French missionary and plant collector who lived in China. I always have a problem with a westerner “discovering” a plant. The locals there had been eating or using it for thousands of years.

Don't eat the seeds

Insignis is often translated to mean remarkable or outstanding but the more accurate Latin use would be “uncommon.” Insignis virtus was a common phrase meaning uncommon valor.  It is said two ways, in-SIG-niss or IN-sig-niss. The D. fargesii is also called  Blue Sausage Fruit, Blue Cucumber Shrub and Blue Bean Tree. And if you are wondering,  Lardizabalaceae is said lahr-dee-zab-uh-LÂ-see-ee.

Oh, and to add to the fun, the fruit ripens around halloween.

I have bought the blue sausage seeds…do I soak them in hot water for 48 hours then put in the fridge for 3 months… Or do I just plant them? Anyone know?

I have this plant! It’s just a 5″ plant now…

I was thinking about ordering seed for Rainbow Eucalyptus, they are so beautiful! I tried my hand at Lotus and failed, but… I still have a few more seeds. 😉

Might I suggest the idea (when you’re stuck thinking about new subjects on which to write) the “rainbow tree” (Eucalyptus deglupta) It’s beautifully colored & odd.
