They arise on handsome shrubs 8 to 12 feet tall and 4 to 6 feet wide. Few shrubs are more heat- and humidity-tolerant than Hibiscus, which basks in temperatures that make others wilt and brown out!

They also reproduce rapidly and can produce up to three generations annually. You can usually identify their mollusk handiwork by the shiny trail of mucus they leave behind as they move.
They tend to chew leaves from their outer edges and may devour a young plant right down to the stem and a few of the tougher leaf mid ribs. Slugs originally had shells like snails, but abandoned them in favor of their ability to hide in crevices in the soil and under rocks they burrow down into the soil when it gets too cold or hot.
