They'll be fine sown direct I would think - mine always have been . I've over wintered a few that are already growing strongly (to produce seed for the end of this year).
I'll be drilling peas and beans soon too. The Yacon seems to have over wintered well - I'll have enough to offer a few plants here if anyone is interested in the really unusual stuff?
