Alcea rosea Alcea rosea Alcea rosea, the common hollyhock, is an ornamental plant in the family Malvaceae. It was imported into Europe from southwestern China during, or possibly before, the 15th century. William Turner, a herbalist of the time, gave it the name "holyoke" from which the English name derives. "Alcea rosea" is variously described as a biennial (having a two-year life cycle), as an annual, or as a short-lived perennial. It frequently self-sows, which may create a perception that the plants are perennial. The plant may flower during its first year when sown early. It will grow in a wide range
Clonostachys rosea f. rosea penetrate, and grow inside the hyphae and conidia of "B. cinerea". Nematodes are infected by "C. rosea" when the fungus' conidia attach to their cuticle and germinate, going on to produce germ tubes which penetrate the host's body and kill it. In 2008 an isolate of "Clonostachys rosea" (NRRL 50072) was identified as producing a series of volatile compounds that are similar to some existing fuels. However, the taxonomy of this isolate was later revised to "Ascocoryne sarcoides". Clonostachys rosea f. rosea Clonostachys rosea f. rosea, also known as Gliocladium roseum, is a species of fungus in the family Bionectriaceae.
