Hibiscus acetosella
''Hibiscus acetosella'' (cranberry hibiscus or African rosemallow) is an angiosperm of the genus ''Hibiscus'' or rosemallow. The word ''acetosella'' is of Latin origin and is derived from an old name for sorrel (Oxalis) which comes from the sour taste experienced when eating the young leaves of the plant.〔Klingaman, Gerald (23 September 2011). ("Plant of the Week: Red-Leafed Hibiscus, Latin: Hibiscus acetosella." ) Division of Agriculture, University of Arkansas.〕 ''Hibiscus acetosella'' is also known colloquially as false roselle, maroon mallow, red leaved hibiscus, and red shield hibiscus.〔 It is one of the approximately 200–300 species that are seen in sub-tropic and tropic regions.〔 This ornamental is usually found in abandoned fields or open areas, marshes, and forest clearings. Cranberry hibiscus is a member of a perennial group known as hardy hibiscus.〔 In contrast to the tropical hibiscus, hardy hibiscus can tolerate colder conditions, are more vigorous, longer lasting, and have larger flowers.〔Knox, Gary W. ("Hardy Hibiscus for Florida Landscapes" ). University of Florida Extension. Retrieved 2013-06-02〕 In colder climates, ''Hibiscus acetosella'' is easily an annual, but is often regarded as a perennial to zone 8–11. During one season, the plant can grow tall and wide as a shrub-subshrub.〔Mahr, Susan (21 April 2008). ("Hibiscus Acetosella." ) Wisconsin Master Gardener. University of Wisconsin.〕
==Characteristics==
The foliage of cranberry hibiscus is similar to that of the Japanese maple. It has dicot leaves which vary in shape from 3-5-lobed to un-lobed or undivided in the upper leaves of the plant and are generally the size of a small child's hand, about 10×10 cm.〔〔("PLANTS Profile: ''Hibiscus acetosella'' Welw. ex Hiern. African rosemallow" ). United States Department of Agriculture.〕 They tend to be alternate, simple, and deeply cut with crenate or jagged edges.〔 Leaf color is observed as a dark maroon to a patchy red/green appearance. Stipules are linear, measured approximately 1.5 cm in length.〔 Both stems and petioles (3–11 cm in length) are smooth or generally free from hair.〔 Acetosella is further divided into a section called Furcaria, which is a group of approximately 100 species that have non-fleshy calyx or sepals.〔 The sepals contain 10 veins, 5 of which run to the apices of the segments; the other 5 run to the sinuses.〔 Stems tend to be variegated.〔 Flowers are solitary and sit atop a 1 cm long pedicel. They vary in color and are most often the dark maroon that is characteristic of the foliage with darker vein-like markings. Flowers are rarely yellow in color and are about 5 cm deep. Each flower contains numerous stamens at about 2 cm in length.〔 The cranberry hibiscus is bisexual and is thought to be self-pollinating. It produces seeds that are reniform and dark brown with dimensions of 3×2.5 mm.〔
