If you have an abundance of slugs and snails in your garden and your favourite delphiniums are disappearing overnight, next time you’re visiting your favourite nursery or garden centre, stock up on plants that are less appealing to slugs and snails.
Hostas are often thought of as the number one dining choice for slugs and snails, but this isn’t the case for every Hosta. Varieties of Hosta that have thicker, puckered, rugose, wrinkled leaves, or varieties with a waxy coating to their leaves – often seen on blue coloured types, are far less attractive to slugs and snails and this offers the plant some resilience and protection. Hosta ‘Sum and Substance’ grows to 0.75cm (about 30 inches) tall and 1.2m (about 47 inches) wide – it’s a huge Hosta! Its attractive heart shaped, chartreuse coloured leaves are glossy and corrugated, they turn more golden as the season progresses. H. ‘Sum and Substance’ is a tough and versatile Hosta that offers good resilience to slugs and snails; it thrives, even in a sunny spot, as with most Hostas, preferring morning sun to afternoon sun.
You can find slug resilient Hostas in all sizes, the diminutive Hosta ‘Blue Mouse Ears’ is a dear little plant with thick, rounded, glaucous blue coloured leaves, shaped like mouse ears. It prefers light to full shade and grows to just 10cm (about 4 inches) tall, forming a symmetrical clump. Hosta ‘First Frost’ starts the season with glaucous blue leaves with yellow margins, as the season progresses, the leaf margins or edges pale to white. H. ‘First Frost’ grows to about 40cm (16 inches) tall.
There are many other Hostas with resilience to slugs and snails including H. ‘Spilt Milk’, H. ‘Devon Green’ H. ‘Halcyon’ and H. ‘June’. All of the Hostas I’ve mentioned here have received the Royal Horticultural Society’s Award of Garden Merit; hopefully if you like them, you can find them at your local nursery or garden centre.
Roses aren’t troubled by slugs and snails, although they do suffer with other pests and diseases. Naturally robust, healthy roses, such as Rosa ‘Crocus Rose’, bred by David Austin, are an absolute delight to grow. I’ve grown this reliable, strong and healthy rose in many different soils and situations, from Scotland to Surrey, often neglecting it terribly, it has always thrived. Rosa ‘Crocus Rose’ has a light and delicate tea rose fragrance; it flowers freely, the pale apricot coloured flowers fade to cream as they age. It’s a charming rose that I wouldn’t hesitate to recommend. Rosa ‘Wild Edric’ is another exceptionally healthy rose, with a strong, beautiful old rose fragrance; it makes a fabulously scented hedge.
I love the gentle, sugar coated tones of Japanese anemones, their flowers add a warming glow and gentle softness to the garden as summer fades away. Look out for the beautiful white flowered Anemone x hybrida ‘Honorine Jobert’ and the rose-pink flowered Anemone x hybrida ‘Königin Charlotte’, (pictured at the top of the page), both of which have been awarded the Royal Horticultural Society’s Award of Garden Merit; I’ve never seen them with any slug or snail damage.
Ferns are an absolute must have for anyone concerned about slugs or snails in their garden, as they are incredibly resilient. Don’t forget Digitalis, Astrantia, Aquilegia, Lamprocapnos, Alliums, Hellebores, Cyclamen, Heuchera, Knautia macedonica and Verbascum, as these are beautiful plants that aren’t usually on the menu for either slugs or snails.
