Edible Uses

Edible Parts: Leaves;  Root.
Edible Uses:

Tubers - raw or cooked[1, 2, 4, 16, 33]. Quite a pleasant mild flavour and easily digested[46], but fairly small and fiddly[K], they are about 5 - 8cm long and 2cm wide[200, 206]. A nutty artichoke-like flavour[183], it can be eaten raw on its own, be added to salads or be lightly cooked[K]. The tubers quickly discolour when exposed to the air[200] and are said to lose their flavour if they are peeled[183]. It is best to harvest them as required[206]. Yields are about 1kg per square metre[200]. Leaves - cooked. A famine food, they are only used when all else fails[179].

Cultivation details

Prefers a well-drained soil in a sunny position[16]. Thrives in an ordinary garden soil[1], preferring one that is not too heavy[16, 33]. It grows best in a soil that has been well fed and does not dry out in the growing season[16]. Plants seem to withstand even water-logged conditions in the winter[206]. The Chinese artichoke is occasionally cultivated for its edible tubers, they are planted out in March and harvested from October onwards[1, 58, 61]. Although top growth is killed back by frost, the tubers are very hardy and can be left in the ground over winter to be harvested as required[200]. It is virtually impossible to find all the tubers, there are always some left behind that will grow the following season[K]. Plants are very tolerant of high summer temperatures[206]. The tubers begin to sprout at temperatures above about 5°c[206]. Plants take 5 - 7 months to develop their tubers[206]. Plants rarely flower in Britain[1].

Propagation

Seed - sow spring in a cold frame. Prick out the seedlings into individual pots when they are large enough to handle. If sufficient growth has been made, it is possible to plant them out during the summer, otherwise grow them on in pots for their first summer, leaving the tubers in the pots to overwinter in a cold frame and then plant out in late spring when in active growth. Seed is rarely if ever produced on plants growing in Britain. Division. The tubers can be harvest and replanted at any time whilst they are dormant. They do start into growth fairly early in the year so it is better to have moved them by the end of March[K].

Id rate the plant as somewhat frost tolerant rather than tender. Seems to need a longer growing season than I have.. yields are low but it grows easily. Invasive.. tubers are very cold tolerant. Small and fiddly yes but easy enough to clean. Id say the flavor is good but a bit too mild. Possibly production could be increased with better knowlege of fertization requirements.. perhaps I gave it too much nitrogen. Id like to experiment with some of the other wild Stachys and I wonder why some selection for tuber size doesnt seem to have occurred. Are their cultivars of this we are not aware of. French.. crosne, Japanese... chorogi ??

This is the normal growth patter of Stachys affinis, though plants usually grow taller - ours are usually 30 - 50cm tall. The reason plants seldom flower in Britain is because the summer is not normally hot enough to initiate flowering - I wonder if this will change if we continue to get hotter summers with global warming. Instead of flowering, the plants concentrate on root growth, send up lots of new growth from these roots and therefore producing a tight clump with lots of stems.

where can I get seeds?

Ken Fern, Plants for a Future   Wed Nov 22 2006

This plant is not normally propagated by seed. The usual method is to obtain the small tubers and plant these out in early spring. There are a number of nurseries that offer the tubers in Britain, visit the Plant Finder at http://www.rhs.org.uk/RHSPlantFinder/plantfinder.asp for details of these.

Oh, my gosh. I have been digging this out from around my mini-pond for YEARS. Invasive? You bet. Edible? I didn't know -- maybe this will give me something to do with this beastly plant.

Does anyone know of a Canadian nursery that ships stachys affinis? I can find only American and British ones, and am not sure that these tubers will be allowed past customs.

Nigel Murison   Sun Oct 12 2008

I grew these for the fist time this year and most if not all plants flowered,seeds seemed to be developing but didn't come to much in the end. As it seems to be found in wet places I will try growing these in watery places next year.

Nigel Murison   Sun Oct 12 2008

I forgot to add, that I grew these on the Rame Peninsula in East Cornwall.

Kristin Kaspersen   Wed Nov 5 2008

Grows like a weed in southern Norway. I received some tubers a couple of years ago, and this summer they flowered for the first time.

You can buy some in Canada (Quebec) there

We have a plant that grows wild here in the state of Florida (U.S.A.)named STACHYS FLORIDANA.I have been eating the tubers/roots of this plant for many years ,BOTH RAW AND COOKED,and I have a patch that grows in my back yard about 10 feet square. In my opinion,Stachys AFFINIS and Stachys FLORIDANA are actually the EXACT SAME PLANT with 2 Latin names!Remember that both are considered to be "weeds" and keep them away from your other garden areas.Stachys Affinis,or CROSNES,or S.Floridana, sells by the pound for more than $40.00 in big cities with gourmet restaurants.
