Rue Anemone

Anemonella thalictroides

The Story

Plant Bio

Anemonella thalictroides, rue anemone, is a delicate clumping woodland perennial native to eastern and central North America, only four to eight inches high. Slender reddish-brown stems carry finely divided blue-green leaflets, and cup-shaped white or pink flowers with showy sepals open in loose clusters in early spring.

It is a spring ephemeral: it flowers, sets seed and dies back completely by early summer, which is normal and not failure. Mark the position, since the dormant tubers are easily destroyed by a spade in July. Its hollow dead stems are used by stem-nesting bees, so leave the spent growth rather than tidying it away.

Uses & Benefits:

Ornamental UsesDelicate white or pink cup-shaped flowers over fine blue-green foliage, very early in spring.
Practical UsesOne of the daintiest natives for a shaded woodland floor, needing no attention once settled.
Ecological BenefitsFeeds bees and moths in early spring, and the hollow dead stems shelter stem-nesting bees.

Planting

How to Grow

  1. Plant in dappled to deep shade under deciduous trees.
  2. Give it moist, humus-rich, freely draining soil.
  3. Mark the position before it dies back.
  4. Leave the dead stems standing for nesting bees.
  5. Mulch with leaf mould each autumn.
  6. Avoid disturbing the soil once dormant.

Pro Tip

It vanishes entirely by midsummer, so mark the clump — far more plants are lost to a summer spade than to any pest.
