Flowering verbena are very popular on the balcony, terrace or in the garden. Easy-care and colorful, hobby gardeners rely on verbena. But is verbena also hardy?

In a nutshell

  • Different species make different demands on the environment, temperature and more.
  • Vervains prefer nutrient-rich soil and a sunny location
  • Protective devices for frost-sensitive verbena are usually not sufficient in winter
  • Transplant and winter well inside the house structure

Different varieties

Many gardeners make the mistake of generalizing. Because there are numerous variants of the iron herbs, which differ significantly in terms of their winter hardiness. Vervain (Verbena officinalis), for example, is a frost-hardy specimen that does not require special frost protection in winter. Consequently, this variety of verbena can easily overwinter outside. The following variants are also hardy:

demands of the plant

Verbena is a popular garden plant that gives off a spicy scent in the garden. The plant is resistant and persistent. In order to thrive magnificently and permanently, the easy-care plant has different requirements. On the one hand, a sunny spot is recommended, while the plant also loves moisture. A nutrient-rich soil and fertilizing every 2 weeks also help ensure that the verbena herb remains stable.

Hibernating verbena - instructions

The situation is different with the frost-sensitive iron herbs. You have to overwinter these with a little more effort. This rarely works well outdoors, since leaves and twigs do not provide sufficient protection from the cold. The frost succeeds through the protective layer and destroys the plant. Consequently, you should proceed as follows when overwintering verbena:

  • Cut back in autumn
  • Set up the pot in a frost-free environment
  • regular airing
  • water evenly but little
  • Transplant to the old site in May

New sowing

If you don't want to bother with transplanting, you can simply sow the seeds again. Verbena is a viable plant. When sowing, you should prefer the seeds at home. It is then possible to resettle in the bed.

Notice: Vervain seeds need a cold period to germinate at all. In the spring, the seeds can germinate and new plants grow.
