Slender vervain (Verbena rigida): how to prune it?
- Leave the old stems standing in winter: they protect the base from frost.
- In April, cut all dead stems back to just above the new shoots.
- In summer you can snip off faded spikes to prolong flowering.
How much to cut, and how often?
- One pruning period a year: April.
What does it mean for wildlife?
- Slender vervain (Verbena rigida) flowers in June–October, when it attracts bees and butterflies.
- If you only cut back in April, the old stems stand through the winter: insects overwinter in them and birds eat the seeds.
Caution: Do not cut back in autumn: a plant cut to the ground survives the winter less well.
