Alcea three centimeters wide and may be pink, white, purple, or yellow. The fruit is a schizocarp, a dry disc divided into over 15 sections that contain seeds. There are about 60 species of "Alcea", including: Hollyhocks are popular garden ornamental plants. They are easily grown from seed. Breeds with red flowers attract hummingbirds and butterflies. Cultivars have been bred, especially from "A. rosea". They include the double-flowered 'Chater's Double', the raspberry-colored 'Creme de Cassis', and 'The Watchman', which has dark, nearly black, maroon flowers. The stems of hollyhocks can be used as firewood, and the roots have been used medicinally.
Armatimonas rosea width and 2.4–3.2 µm in length. Neither spores nor flagella were observed. When investigated in R2A media, cultures of "A. rosea" were observed to be aerobic and chemoheterotrophic with no evidence of growth under anaerobic conditions. It is negative for the following tests: nitrate respiration, fermentative growth, catalase, and cytochrome oxidase. Armatimonas rosea Armatimonas rosea is a Gram-negative bacterium and also the first species to be characterized within the phylum Armatimonadetes. The Armatimonadetes were previously known as candidate phylum OP10. OP10 was composed solely of environmental 16S rRNA gene clone sequences prior to "A. rosea's" discovery. "A. rosea" was originally
