What's eating my nepeta sibirica 'souvenir d'andré chaudron'?

Nepeta sibirica 'Souvenir d'André Chaudron' shares the genus's aromatic pest resistance — deer and rabbits rarely touch it. Cats are attracted to the foliage and can crush plants by rolling. Aphids may colonize new shoot tips in spring, and flea beetles create shothole damage on young leaves. A generally low-maintenance, pest-resilient perennial.

Stems crushed and crowns flattened from rolling; nepetalactone scent attracts cats strongly Wire mesh cloches over young plants; lay prickly prunings around crowns; most damage occurs to newly planted specimens

Small colonies on soft shoot tips and emerging flower spikes in spring; minimal compared to non-aromatic plants Water jet or insecticidal soap; natural predators (ladybirds, parasitic wasps) usually sufficient; avoid excess nitrogen feeding

Small round holes across leaf surfaces; adults jump when disturbed; worst on young spring foliage Insect-proof mesh on new plantings; encourage predatory ground beetles; pyrethrin if infestation is heavy
