Slugs can ravage a plant. They love the tender shoots of delphinium, and hosta and crave bedding plants. It's disheartening to find a lovely plant covered in slime trails and reduced to a few sticky branches.
It's true to say some gardens and gardeners suffer more from slugs than others, and no amount of slug defences keep them at bay. Fight the war against slugs, here are some tips. My favourite is beer traps, effective, but smelly. All the various means of warding off slugs take time, and what if there isn't enough time, or perhaps in shadier and wetter gardens the slugs seem to win?
One answer is to choose plants the slugs don't choose. Some plants have better defences against slugs. This may be because they have hairy leaves or are spiny. There are also plants which contain bitter substances which are repellant to slugs. We know Hosta is amongst the slug's favourite snacks, but there are slug-resistant Hostas with tough leaves that even the raspy tongue of a slug cannot chew. There is an excellent selection of Hostas which are resistant to slugs and well worth growing.
Listed below are some easy-to-grow perennials which are resistant, but not infallible to slugs. It means when planning and planting, if slugs are a bugbear, rather than planting, say Lobelia cardinalis, which has lovely red flowers, pick the Astilbe Fanal, illustrated below, which is also a lovely red, and the slugs will give it a miss.
