Names

Michel Adanson (1727–1806), who named the genus Asimina

The genus name Asimina was first described and named by Michel Adanson, a French naturalist of Scottish descent. The name is adapted from a Native American term of unknown origin, assimin,[8] through the French colonial asiminier.[9]

The common name (American) pawpaw, also spelled paw paw, paw-paw, and papaw, probably derives from the Spanish papaya, perhaps because of the superficial similarity of their fruits.[10]

Description

Pawpaws are shrubs or small trees to 2–12 m (6.6–39.4 ft) tall. The northern, cold-tolerant common pawpaw (A. triloba) is deciduous, while the southern species are often evergreen.

The leaves are alternate, obovate, entire, 20–35 cm (7.9–13.8 in) long and 10–15 cm (3.9–5.9 in) broad.

The flowers of pawpaws are produced singly or in clusters of up to eight together; they are large, 4–6 cm across, perfect, with three sepals and six petals (three large outer petals, three smaller inner petals). The petal color varies from white to purple or red-brown.

The fruit of the common pawpaw is a large, edible berry, 5–16 cm (2.0–6.3 in) long and 3–7 cm (1.2–2.8 in) broad, weighing from 20–500 g (0.71–17.64 oz), with numerous seeds; it is green when unripe, maturing to yellow or brown. It has a flavor somewhat similar to both banana and mango, varying significantly by cultivar, and has more protein than most fruits.[5]

Ecology

The common pawpaw is native to shady, rich bottom lands, where it often forms a dense undergrowth in the forest, often appearing as a patch or thicket of individual, small, slender trees.

Pawpaw flowers are insect-

carrion beetles for cross pollination.[24] Other insects that are attracted to pawpaw plants include scavenging fruit flies, carrion flies and beetles. Because of difficult pollination, some[who?
] believe the flowers are self-incompatible.

Pawpaw fruit may be eaten by foxes, opossums, squirrels, and raccoons. Pawpaw leaves and twigs are seldom consumed by rabbits or deer.[25]

The leaves, twigs, and bark of the common pawpaw tree contain natural insecticides known as acetogenins.[26]

Larvae of the

zebra swallowtail butterfly feed exclusively on young leaves of the various pawpaw species, but never occur in great numbers on the plants.[27]

The pawpaw is considered an evolutionary anachronism, where a now-extinct evolutionary partner, such as a Pleistocene megafauna species, formerly consumed the fruit and assisted in seed dispersal.[28]

Cultivation and uses

Asimina triloba is often called "prairie banana" because of its banana-like, creamy texture and flavor.

Wild-collected fruits of the common pawpaw (A. triloba) have long been a favorite treat throughout the tree's extensive native range in eastern North America.

jams or jellies, and pressure canning. The fruit pulp is also often used locally in baked dessert recipes,[30] with pawpaw often substituted in many banana
-based recipes.

The common pawpaw is of interest in

ecological restoration plantings, since this tree grows well in wet soil and has a strong tendency to form well-rooted clonal thickets.[citation needed
]

History

The earliest documentation of pawpaws is in the 1541 report of the

de Soto expedition, who found Native Americans cultivating it east of the Mississippi River. Chilled pawpaw fruit was a favorite dessert of George Washington, and Thomas Jefferson planted it at his home in Virginia, Monticello. The Lewis and Clark Expedition sometimes subsisted on pawpaws during their travels. Daniel Boone was also a consumer and fan of the pawpaw. The common pawpaw was designated as the Ohio state native fruit in 2009.[31][32]
Numerous pawpaw festivals have celebrated the plant and its fruit.
