Only a few varieties of shrub veronica or Hebe are really hardy. Most species tolerate little or no frost. Perennials will only survive in the garden if you overwinter them properly, but even then it is not certain that the plants will survive.
How should shrub veronica be prepared for winter?
To overwinter shrub veronica successfully, cover the plant in the garden with mulch and pine branches. In the house it needs a bright location, temperatures between 5-10 degrees and a moderate supply of moisture.
Overwintering shrub veronica in the garden
Most Hebe species are only partially hardy. They can tolerate a maximum of minus five degrees, and that only for a few days.
If you want to overwinter shrub veronica in the garden, spread a thick layer of mulch made from grass clippings or leaves.
Cover the plants with pine branches or brushwood. However, this doesn't always help in an unprotected location. If the winter is very cold, you have to expect that the shrub veronica will suffer from moisture and cold despite winter protection.
