How to grow False Mitrewort
Planting
Plant in autumn or spring under shrubs or on the shaded side of a border, in soil enriched with leaf mould. It runs gently by surface stolons to make useful groundcover, so plant about 30 cm apart and let it fill in.
Pruning
Remove the spent flower spikes to keep it tidy. Tidy away any scorched or tattered leaves in early spring; the foliage is largely evergreen in mild winters and is best left on over the cold months.
Propagation
Detach rooted runners in spring or early autumn and replant them — this is straightforward and reliable. Clumps can also be divided in spring.
Pests and diseases
Vine weevil grubs can damage the roots of container-grown plants. Slug damage to young foliage is possible but usually light.
Value to wildlife
Early bees and hoverflies visit the flower spikes at a thin time of year for shade-garden nectar.
Notes
It will not tolerate dry shade — the hard, root-filled ground under a mature beech or conifer is the wrong home. Mulch annually with leaf mould to keep it going.
