The wood anemone is a charming spring ephemeral that carpets forest floors with delicate white flowers. It thrives in cool, shaded woodland settings where it can emerge early before the tree canopy fills in. You will find it goes dormant by midsummer, so do not worry if it disappears.

Propagation
division, seed
When to plant
spring, autumn
Overwintering
The plant is fully dormant in winter. You do not need to do anything, as the rhizomes are hardy underground.
In containers
It is not well suited for containers as it requires specific woodland soil conditions.

Division

  1. 1. Wait until the plant is dormant in late summer.
  2. 2. Carefully dig up the rhizome cluster.
  3. 3. Gently pull the rhizomes apart.
  4. 4. Replant immediately in a shady spot.

Plant these in groups under deciduous trees to mimic their natural woodland home.

Grows well with

  • Trillium · They share the same woodland habitat and bloom timing.
  • Wild Ginger · It provides a nice contrasting texture to the delicate anemone foliage.

Similar species

  • Rue Anemone · It looks very similar but has different leaf structures.
