Long-flowered Sage (Salvia longiflora) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.

Borderline hardy in the UK; a combination of wet soil and frost is lethal. Protect with a dry mulch over the crown in autumn, or lift and pot up to overwinter under glass.
Aphid infestations on new growth
Soft shoot tips attract aphids in spring; inspect regularly and treat with a strong water jet, insecticidal soap, or encourage ladybird populations nearby.
