Alcea "Alcea" species are used as food plants by the larvae of some Lepidoptera species including "Bucculatrix quadrigemina" and "Vanessa cardui", the painted lady. The mallow flea beetle ("Podagrica fuscicornis") is a pest that makes tiny holes in the leaves. Cutworms, aphids, and capsid bugs use the plant as a food source in hotter and drier conditions. A number of weevils use "A. rosea" as their host plant, including "Rhopalapion longirostre", "Alocentron curvirostre", and "Aspidapion validum". The plants are also susceptible to the pathogenic fungus "Puccinia malvacearum", the hollyhock rust. A hollyhock flower, known in Japan as , was incorporated into
Sarracenia rosea the species epithet. Sarracenia rosea Sarracenia rosea is a species of pitcher plant in the genus "Sarracenia" and is sometimes known as Burk's southern pitcherplant. It was previously classified as a variety of "S. purpurea" subsp. "venosa" (var. "burkii"). The proposition for the plant to be named a new species arose in 1999. This proposition was based on three main factors: "S. rosea" has larger flowers on shorter stalks; it produces light pink petals, a feature no other species in the genus exhibits; and it has a somewhat different pitcher structure than "S. purpurea". A form which lacks anthocyanins has
