What's eating my brunnera macrophylla 'jack frost'?

Brunnera 'Jack Frost' suffers most from slugs and snails devouring its large, decorative silver-veined leaves in spring. Vine weevil grubs can damage roots in container plantings. Aphids occasionally visit the forget-me-not flower clusters. In deer country, the lush foliage may be browsed. Otherwise this is a remarkably trouble-free shade perennial.

Ragged holes in the large silvery leaves, particularly after rain or in shaded, moist conditions. Iron phosphate pellets; grit or sharp-sand mulch; encourage hedgehogs and ground beetles; hand-pick at dusk.

Creamy C-shaped grubs eat roots below soil level causing wilting and crown death, particularly in containers. Apply pathogenic nematodes (Steinernema kraussei) to moist compost in late summer or early autumn.

Small colonies on flower stems in spring; minor damage but can transmit viruses in susceptible situations. Pinch out infested tips; spray with insecticidal soap; natural predators usually keep numbers low.
