Can verbena survive winter?
Potted verbena can be overwintered. Unless you dig up the entire plant, unpotted verbena will most likely be killed off by the first hard frost. The plant should be cut back to less than half of its original size. Place it in a plastic bag and seal it with a rubber band. Place the bag in the freezer for at least two hours, or until it is completely frozen.
This will allow the roots to thaw and the potting mix to harden. You can also freeze the whole plant, but this is not recommended because of the risk of frost damage to the root system. If you do this, you will need to re-pot your plant every two to three weeks to keep it from getting too cold. Once it has thawed, it will be ready to plant again.
