Anemone perennials that bloom in autumn are usually hardy and do not require winter protection. Anemones from flower bulbs, on the other hand, almost never survive cold winters. They should always be kept indoors over the winter.
How should anemones be protected in winter?
For overwintering anemones, hardy perennial anemones should be covered with dry leaves, straw or brushwood in the first year. Anemones from flower bulbs, on the other hand, must be dug up in autumn and overwintered in a frost-free place.
Protect perennials from frost in the first year
Older anemone perennials are frost hardy. They don't mind cold winters. However, you should cover autumn anemones planted at the beginning of the year to be on the safe side.
- Leaves
- Straw
- brushwood
Only use dry materials to prevent the anemones from rotting.
Dig up tubers in autumn and overwinter in the house
Anemones from tubers are almost never hardy. Dig them up in autumn and overwinter them in a frost-free place. Replant the bulbs in early spring.
Tips & Tricks
If you buy anemone bulbs commercially, you will find a note on the package as to whether the variety is hardy. You shouldn't rely on that. Most bulbous anemones cannot survive subzero temperatures outdoors.
