May your garden flower in a thousand colors—in spite of slugs.
There are some flowers that slugs and snails are especially attracted to, for example:
Fortunately, there is a much longer list of flowers that slugs and snails do not like to eat.
Here you will find nearly two hundred different annuals and perennials that under normal conditions are slug-resistant.
Why Are Some Plants More Slug-Resistant Than Others?
Many plants developed a way to protect themselves against predators.
They had to because they cannot run away!
Therefore, they have developed various methods to become resistant:
- Toxic ingredients
- Hard and leathery leaves
- Hairy leaves
- Bitter substances
- Hard-to-digest substances
- Thorns and spines on stems and leaves
- Stinging hairs
These are the main defense mechanisms of plants, and there are many more.
Some plants, such as the tobacco plant, even call other animals to help by emitting scents.
Plants that are preferred by slugs have often lost their defense mechanisms as a result of plant breeding.
Most humans do not like to taste bitter salad greens or vegetables, and the same is true for most slugs and snails.
For a gardener, it is also important to know which plants are especially loved by slugs and snails.
Then you can avoid some of them and replace them with resistant varieties.
Apart from resistant flowering plants, there are also many herbs and vegetables which slugs do not like.
Slug-Resistant Flowers: Annuals and Perennials
The alphabetical list below consists of flowering plants which have been able to defend themselves against slugs and snails.
However, please be aware that most slugs and snails are omnivores, which means they can eat anything.
If they do not find alternatives, they may also eat some of the listed plants.
Nevertheless, some plant families are particularly resistant towards slugs, such as the following:
But even these families might not always be safe.
There are many factors that influence the resistance of a plant.
In some plant families, the susceptibility is dependent on the subspecies.
For example, mints, daylilies, or irises are sometimes spared but sometimes eaten.
Also, the location where a plant is growing can play a role, as can the season and the power of the plants to protect themselves.
Slugs prefer weak, sick, dying, or freshly translated plants.
Young plants may be especially vulnerable and prone to attacks by slugs and snails.
The following list provides a selection of beautiful flowering plants that can be cultivated without much danger of slugs or snails eating them.
Many summer flowers, annuals, and perennials are among them.
With this list at hand, it is possible to create a snail- and slug-resistant flower paradise.
Some seed companies already offer special seed mixtures and tapes consisting only of flower seeds, which slugs avoid and are reluctant to eat.
Some breeders already focus on slug-resistant varieties.
For example, slug-resistant hostas are available (more information from Amazon).

Planting and sowing these plants are perhaps the easiest ways to avoid a snail problem from the start!
If you do not want to give up on marigolds, hostas, dahlias, larkspurs, and company—all favorites of the snails—you can use different means and methods to protect them.

How to Protect Endangered Plants?
There are a number of things to consider when dealing with snails and slugs.
First, you need to understand the causes and condition behind the snail or slug boom in your garden.
Then you will be able to find sustainable solutions and countermeasures.
If you find out that the natural predators of slugs have left your garden the solution will be to reintroduce them, which will take some time.
In this situation, slug barriers can help by providing immediate protection for plants mechanically stopping slugs and snails.
They will help your plants to withstand slug attacks until more natural enemies start to settle.
Another interesting option is to distract slugs and snails from vulnerable plants by creating sacrificial flower and vegetable beds.
In these beds, you feed them with plants and food they love to eat.
Then they might leave everything else, and it will become easy to set up live slug traps and to pick them up.
These methods can help a little but usually do not lead to the desired success.
Please do not put too much hope in these techniques.
I tested and compared the recommended mulch materials against slugs.
Most of them fail completely if it begins to rain.
However, sheep wool pellets had a deterring effect on slugs and snails and can be recommended.
I hope you liked this article and that I could help you a little!
