Jordskokkeksperimentet (Jerusalem artichoke experiment)

English: In 2001, I was growing  7 different varieties of Jerusalem artichoke (jordskokk). As my garden wasn’t in an optimal location climatically, I was interested to see offer these varieties for others to try.  I was active on a Norwegian  gardening forum called Hagepraten and offered a couple of tubers of each variety to forum members.  The varieties I had were Bianca and Dagnøytral (the only varieties that flowered here and they were most likely the same variety- few large tubers); Golden nuggett; Volgo 2 , Red Italian (from a market in Venice), Fuseau; and Hardy Mountain. Despite the fact that several had small tubers, I noted that  they all gave a useful crop. I concluded that I would try Golden Nugget, Hardy Mountain and Volgo 2 again.

Norwegian (dette var min invitasjon til eksperimentet): Jeg har 7 forskjellige sorter: Bianca og Dagnøytral (eneste sortene som blomstret og de er mest sannsynlig samme sort – få men store knoller); Golden Nuggett (rett gyldne med rose skjær, avlange knoller); Volgo 2(runde mange små knoller), Red Italian (kronglete, rød), Fuseau (en rett hvit sort som jeg har dyrket i flere år; mange små knoller); Hardy Mountain (rød rett sort). Tross at flere av sortene hadde mindre knoller synes jeg at alle gav brukbar avling (også her i Trøndelag). Av de nye, ville jeg prøver Golden Nugget, Hardy Mountain og Volgo 2 igjen. Har tenkt det kunne være interessant med et lite forsøk blant oss her på hagepraten. Jeg kan dele ut et par knoller av noen av sortene til flere til utprøving.

I didn’t get much feedback from those that I sent tubers, the best report being this thorough one below from 2003 from Sverre Håskjold in Ålesund.  I didn’t continue growing Golden Nugget, Hardy Mountain and Volgo 2 as they gave very poor yields in colder summers. I wonder if anyone is still growing them.
