Hibiscus varieties such as the popular rose mallow are not hardy.
Before the first frost, these varieties should therefore migrate into the warm.
Whether for freshly brewed tea made from the dried leaves or simply as an aesthetic highlight in the garden: hibiscus is popular because it gives gardens a romantic accent with its yellow, purple, red or blue flowers.
But not all of the 200 varieties are hardy.

In contrast, garden and perennial hibiscus are hardy, as the

(NDR) knows.
Likewise, shrub marshmallow, scarlet hibiscus and marsh marshmallow.
Since the rose marshmallow is often kept in a bucket on the balcony and terrace, moving indoors is not too complicated.
However, if you plant the non-hardy varieties in the bed, they must first be dug up before the first frost.
Every transplant stresses a plant and should therefore be avoided.
If you bring the hibiscus indoors from outside, look for a window seat that promises the plant at least six hours of daylight a day.
If this is not possible, you should use an artificial lamp.
