Vervain - floriferous, can be used in pots on the balcony or outdoors and is easy to care for. But what happens to him in winter? Does it need frost protection or is it sufficiently hardy?

It depends on the species

Vervain is not just vervain. In the land of verbena there are numerous specimens that amateur gardeners call verbena. But there are many differences, especially with regard to their frost tolerance.

Vervain (Verbena officinalis), which is native to this country, tolerates frost. It does not require any special frost protection in the form of leaves, brushwood etc. over the winter. Verbena (Verbena hastata) and some Canadian vervain (Verbena canadenis) are also hardy.

Hibernation as an alternative to freezing

You can overwinter frost-sensitive verbena if you care about it. This is only recommended if you have planted your verbena in a pot or bucket and it is on the balcony, for example. It is not worth overwintering frost-sensitive verbena outdoors. A layer of leaves or twigs is usually not enough. The frost penetrates through this layer.

This is how the wintering of frost-sensitive verbena works:

  • Prune verbena in autumn after flowering
  • Place the pot in a frost-free and cool place
  • Ventilate the winter quarters regularly and keep them dark
  • water little but regularly
  • return to its location from mid-May

Alternative number 2: Sow again

Since verbena is easy to germinate, it can easily be sown again every year. For many varieties, this is preferable to overwintering. When sowing, make sure that verbena germinates in the sun and that it is preferable to sow directly in the bed at home.

tips and tricks

Verbena likes to sow itself after the winter. Its seeds need a cold period to germinate. After the winter they are ready in the spring to start the germination process.
