I have found peace lilies survive here and you can divide them too. I have bought plants from Coop, Ikea, Migros plus general garden centres and have found the trick to getting them to flourish is to re-pot them immediately - they will usually need a larger pot and to buy a compost specifically for houseplants. Peace lilies are quite sturdy and will survive a few days neglect. In winter it's probably worthwhile misting the plants with water from a spray bottle because the air becomes dry with the central heating.

I have lavender and rosemary that I leave out all year round. They both need to be pruned right back in the autumn and then the following year they'll pop back up. However they won't provide you with anything over the winter.
