Silverwort is not hardy
How is the silver herb hardy?
The stone weed feels in good hands in rockeries, on dry stone walls, on roofs and in cottage gardens. In addition to blue cushions, there is a high contrast. But what about him in the winter? Is it helplessly exposed and freezing to the forces of nature?
Usually not hardy and only one year old
Although the exterior that presents it during its flowering can remotely remind of snow. But that should not obscure the fact that the silver herb belongs to the Sensibelchen in the bed. It is not hardy.
One reason for the poor winter hardiness is the original distribution of the silver herb. It comes from the Mediterranean, where it inhabits coastal and sandy beaches. As a result, it is cultivated in this country usually only one year.
Cover? Futile?
For example, if the silver herb is outside in the rock garden or in the perennial border, it could survive the winter if it is sufficiently protected and in a mild position. In regions like Rhineland-Palatinate it is worth a try.
Cut the silver herb radically down in autumn! Then check the plant to see if it still has any sick spots. These are removed. Then the cut back crop is covered with brushwood like spruce.
In pot culture, hibernation usually works
Did you keep the silver herb in a bucket or trough on the balcony and you do not want to part with it? Then you can try to overwinter it. The plant should be cut back by 2/3 beforehand. Then it is housed in a cool about 5 ° C room. During the winter you should not fertilize the shrubs, but pour sparingly.
Just sow again after the winter
Do not worry if the silver cabbage is frozen in winter. If you sow it again in the spring, you will be able to admire its flowers again in the summer. Sowing in the field works like this:
Tips
An insider tip is the yellow-flowered rock-silverwort and especially the variety 'Compactum'. It is considered winterproof.
