Hardy potted plants are plants that can also be kept in pots in the winter. Keeping plants in pots is ideal for the balcony or if you have little soil to plant. Keeping pot plants is no problem in the summer, but in the winter most plants get too cold in the pots. If you are still tied to pots, we have selected hardy pot plants for you that you can leave outside in the winter.
Hardy pot plants: they exist!
Many plants that are kept in pots are tub plants. In most cases, these are subtropical or tropical plants. These plants can survive well in a pot during the warm months, but if the mercury drops below zero, it becomes too cold for them.
In most cases, it is then advised to put the pots inside or to put the plants in the solid soil. These two methods limit the frost damage to the plants. Now, however, it is not possible for everyone to put the pots in during the winter or to place the plants in solid soil. You probably recognize this problem if you only have a balcony or small garden. Fortunately, there are enough hardy pot plants. You can safely leave these plants outside in the winter. We have selected 8 fine hardy potted plants for you.
To be able to overwinter in a pot, a plant must be able to survive well in the freezing cold. The reason why pot plants are often put indoors or in the solid ground in the winter is that the roots of a pot plant suffer from the cold in a pot much faster than in the solid ground.
The plants below do not find it a problem to get cold feet and will, therefore, do well during and after the winter.

The Dianthus ‘Kahori’ is an evergreen hardy plant that also works well as a pot plant. In the winter, the plant is even able to handle temperatures up to -15 degrees Celsius.

Grass as an ornamental plant in the garden? Hell yes! With the Stipa tenuissima you bring beautiful ornamental grass to your garden or balcony. The structure of the leaves is so fine that the plant is also called feathered grass.
