3 other perennials to trim now
1 Foeniculum vulgare ‘Purpureum’
– Cut back the flowering stems of bronze fennel to prevent self seeding and to encourage fresh foliage.
2 Alchemilla mollis –
The seed heads of lady’s mantle are not that attractive so cut old flowering stems to ground level.
3 Hemerocallis –
Once flowering is over the foliage of day lilies can look tired. Cut back hard and new foliage will emerge.
