There's not much they won't have a go at, especially nice, tender, new growth on perennials coming through in spring
Daffs and snowdrops are a good start. Shrubs like Potentilla, Berberis, most of the conifers and junipers are trouble free. Rhododendrons and azaleas were fine too. I found vincas quite resistant, although the youngsters will have a go at most things. Jaggy things don't necessarily work - they devour holly for instance. You can use tree guards if you want to grow climbers - it stops them reaching the lower growth. I found it effective on clematis, and honeysuckle. Once the plants are mature enough, they can withstand the onslaught better.
There are more, but I can't remember at the moment. Some years they're worse than others too.
