Slugs on my mum plant
There are a number of slug baits -- both traditional and organic -- on the market that do a good job of controlling slugs. I'd look for one of these from your local garden center, nursery, or online retailer (such as www.gardensalive.com).
Slugs will eat virtually any plant as their populations grow --- I've not found anything that's truly been slug resistant, I'm afraid.
