After 5 months of sitting dead as a Dodo outside, in full sun, showing no sign of life -- and this is in southern France, where the temps are above 25 °C by May -- my Hedychium gardenarium has suddenly decided to sprout!

I don't know what to do with it now: winter can be harsh in Provence, with the thermometer dipping down to -10°C at times. Should I leave this sprouting ginger outside and just mulch it and pray? or dig it up (which may kill the growth) and repot it so that it can be inside over the winter?

Thanks for getting back to me -- Confused in Provence
