The crown anemone (Anemone coronaria) is one of the particularly decorative varieties of anemone. The large flowers are somewhat reminiscent of poppy blossoms and are therefore very popular as spring flowers. The Anemone coronaria is not hardy and must therefore be kept frost-free over the winter.
Is the Anemone Coronaria hardy?
The Anemone coronaria is hardy in its homeland, but not in colder regions. In order to overwinter them frost-free, the tubers should be dug up, dried and stored in a cool, dark and dry place by October at the latest. They can be replanted in spring.
Overwinter Anemone coronaria properly
In its homeland, the crown anemone is hardy and can be grown in flowerbeds for several years. It's too cold here in winter. The tubers would also freeze in a protected place.
Wintering the bulbs indoors is also recommended because the bulbs become more and more leached over the years and produce fewer flowers.
- Dig up tubers by October at the latest
- Remove yellowed leaves
- Store in a cool, dark and dry place
- Plant tubers at the end of March / beginning of April
- Cutting spent flowers
- Do not cut leaves
Get out of the ground before frost
Unlike the flowers, you must not cut the leaves of the Anemone coronaria. The plant gets its strength from the leaves.
It will also make it easier for you to see where your crown anemones are growing and where you need to dig up the bulbs.
You should remove the tubers from the ground by the end of October at the latest. Use a digging fork to pierce generously around the plant remains and lift out the bulbs.
Cut leaves and let onions dry
Before the tubers move into winter quarters, cut off the yellowed leaves and remove all soil residue.
Allow the bulbs to dry thoroughly to protect them from rot.
Store tubers correctly
To properly store the crown anemone tubers, you need a dark and cool place, but it must be frost-free. The place must not be too damp, as the onions will then rot.
The tubers can also be overwintered very well in dry sand (€14.00 on Amazon) or dried peat.
Before you plant the Anemone coronaria tubers back into the ground in spring, water them for a day. The anemone will then sprout again more quickly.
Tips & Tricks
Pre-grown specimens of Anemone coronaria in pots are among the most popular spring bloomers from garden retailers. Similar to primroses, these plants do not tolerate frost. You should only place an early crown anemone indoors.
