I think they do best if they're undisturbed - is it hederafolium? If so it'll begin waking up soon. When we moved here last we found loads of hederafolium alba popping up all over the place in the autumn - I was thrilled as they're one of my absolute favourites - however, because of building work we've had to move them. Some of the corms were the size of dinner plates - neighbours said they've been there for 20 - 30 years. They've been replanted on a shady bank; you've no idea how firmly my fingers are crossed in the hope that they'll be ok.
What are you going to do with yours - replant it?
