Pawpaw trees were discovered in 1541 by the Spanish explorer, Hernando Desoto, on an excursion into the Mississippi Valley, and he sent samples of this plant back to Europe.
William Bartram in 1776 stated in his botanical book, Travels, that he found pawpaw trees growing on the Alatamaha River in Georgia and in east Florida, which he described as, ‘Annona incarna,’ the name later was updated by modern taxonomists. “The fruit the size of a small cucumber …containing a yellow pulp of the consistence of a hard custard, and a very delicious, wholesome food.”
This fruit is agreeably flavored and considered to be the largest native fruit of North America. The pawpaw trees are said to be endangered or threatened in the states of New York and New Jersey, in the forests where it grows naturally.
The pawpaw tree grows across most of the eastern United States as a native tree. Mature pawpaw trees produce fruits 2" wide by 10" long, looking and tasting very much like a banana. The fruit is liked immensely by most people and may be purchased at many outdoor markets in West Virginia, Kentucky, Tennessee, etc. The pawpaw pulp has the consistency of creamy custard and may be eaten raw, baked, or used as a pie filling. The trees grow about 15' tall and have been known to produce as much as 60 pounds of pawpaws per tree. Some individual pawpaws weigh up to a pound each. Zones 5-10
Much interest has been recently directed towards research and development of improved varieties of the pawpaw at Universities in Tennessee, Kentucky, and Ohio. The large fruit is not well known in much of the United States, but its flavor and exotic shape make it a candidate for the expansive, potential of specialty fruit markets in the future. Taste it once fresh and you will feel compelled to have some of these pawpaw trees growing in your personal fruit orchard.
One of the great horticultural mysteries of the world is: why have most paw paw trees, that were plentiful throughout early U.S. forests, virtually disappeared from their natural habitat today? That answer may lie within the research results (Peterson 1991), that showed that the paw paw is sensitive to ultraviolet light, thus, paw paw seedlings may not grow back after the forests have been harvested, and there are very few virgin forests left in the United States. Paw paws can be found growing there abundantly, but once the forests are clean-cut, the paw paw will not usually become re-established.
These experiments must be clearly remembered, when you order your paw paw trees. They must be planted under partial shade of other trees, however, you may plant your pawpaw trees in the open, if the trees are grown under shade cloth for a couple of seasons. The tree will lose its sensitivity to full sunlight once it has become established and the shade cloth can be discarded.
Some gardeners wish to plant their pawpaw trees in pots for a couple of years under shady conditions, but this is not necessary if the above guidelines are followed. Since paw paw trees are tap rooted, growth will be slow during the first year, but after that, very rapid growth occurs afterwards.
Paw paw leaves are large and that large leaf surface generally indicates a need for large amounts of soil moisture, and therefore, generally, paw paws are found in their greatest numbers near river flood plains. Leaves or other organic composted materials are very beneficial to paw paws.
The skin of paw paws is thin and edible and can vary in color from a light green to a golden yellow. Most people prefer to eat the pawpaw fruit after it becomes soft to the touch. The custard- like pulp tastes like banana and varies in color from white to deep orange. The seed are few and large, thus, pawpaws are easy to eat raw.
Most paw paws are sold at roadside markets, because the shelf life is short. Commercially, the paw paw is important in juices, pies, cakes, custards, ice cream and other processed products.
The pawpaw tree was voted by Better Homes and Gardens, in the year 2000, as the landscape tree of the year. The pawpaw and the pawpaw tree are loaded with beneficial health extracts. The bark contains fluids that demonstrate anti-tumor properties and have been used over the years to fight scarlet fever and red skin rashes. These extracts from pawpaw trees are highly useful as an organic insect killer (pesticide).
Pawpaw fruits are rich in minerals such as magnesium, copper, zinc, iron, manganese, potassium, and phosphorus. The fruit also contains abundant concentrations of Vitamin C, proteins, and their derivative amino acids.
There are a number of grafted cultivars of paw paw but their range of adaptation is very narrow, and many cultivars that produce heavy crops of large fruit in Kentucky, Indiana or West Virginia do not perform satisfactorily in Georgia, Florida, Carolina or Alabama. Consider buying improved seedling paw paw trees, which appear to be more adaptable universally. Try some of these trees in your orchard for a real tasty treat.

Modern Fruit Trees Evolved From Ancient Historical Roots
The rise and fall of ancient empires has developed parallel also to the establishment and destruction of advanced fruit tree orchards. Ancient fruit trees such as olive tree orchards increased the wealth and health of nations by feeding the populations, providing nutritious olive oil to light lamps in ancient houses at night, as food and a cooking medium, and for the purpose of anointing Kings and Queens. Olive trees could not produce continuous crops unless the gardeners growing them could...
There are two types of chinquapin trees, also called ‘chikapin trees,’ that are available commercially in the United States, the Allegheny chinquapin and the Georgiana chinquapin. The Allegheny chinquapin, ‘Castanea pumila’, is considered a shrub by some; however, some researchers claim that its dwarf size does not justify its reclassification. Many old-timers remember sweet memories from their youth when baskets were filled with the spicy, sweet, nutty flavored chinquapins. These nuts were...
Cold Hardy Palm Trees For Landscapes In Southern States Zones 8 11
In Southern States, the Northern type palm trees that withstand cold temperatures of -20* F will also thrive in the South. The Northern type palm trees, such as Windmill Palm trees, Trachycarpus fortunei, Needle Palm trees, Rhapidophyllum hystrix, Dwarf palmetto palm tree, Sabal minor, and Dwarf Saw Palmetto palm trees, Serenoa repens, are discussed in another article by the same author called “Cold Hardy Palm Trees for Landscape Design and Planting in the United States.” Other palm trees that...
Phoenix Palm Trees For Landscapes And Offices
Commercially, the Phoenix genus of palm trees is broad and very desirable for use in landscape situations of the south, and to decorate offices. Huge specimens of the Canary Island Date Palm, Phoenix canariensis, show considerable cold hardy qualities in northern parts of southern states such as zone 7. Phoenix sylvestris can also be used as landscape specimen for landscapers who look for slender trunks. The Medjool date palm, Phoenix dactylifera, can be planted as a fruit tree to produce...
History Of Oak Trees Quercus Sp
Heroditus, the father of ancient history, recorded in the mid-400's B.C., that oak trees were reputed to have within their boughs, the gift of prophecy. The presence of oak tree galls in oak trees is caused by insect larvae that tunnel inside the twigs. The oak tree branches can become infested with numerous little galls that look like brown or tan balls, as the cells of the oak tree grow to surround the insects inside. Some cultures call these creations, 'Oak Apples,' and they are used...
History Of The Jujube Tree
Chinese poets spoke about the wonderful jujube in 600 BC. The fruit of the jujube has been used in ancient Chinese medicine for many nutritional remedies for 2500 years. Jujubes were used by Gerard in Europe as a medicinal herb in the 1600’s to treat ailments of the kidneys, lungs, and liver.
The Chinese jujube was brought to America by Oriental immigrants who built railroads in Arizona in the early 1900’s. Hundreds of grafted jujube cultivars are available in China, and a large number of...
History Of The Strawberry And The Strawberry Tree
It is difficult to trace the ancient history of the strawberry plant or strawberry tree, because there are so many different, complex, undefined species, and they have evolved in so many different places and countries.
Pliny described the strawberry tree, Arbutus in his early writings of the Roman culture in the first century, AD.
Strawberry trees, Cudrania tricuspidata, have been known since antiquity and have been so named because the berries growing on the trees resemble the familiar...
