History of Apple Trees

Apple trees were the most popularly grown fruit tree in colonial America and practically every settlement farm and backyard gardener planted this easily grown fruit tree, or easier, the seed of the apple could be planted to establish a permanent food supply. Growing these apple tree products could be eaten fresh or could be dried and preserved in many different ways to eat at a later time. Historical instances on the existence of apple trees are documented from folklore, legends, stone images on carved tablets, petrified slices of apples on plates for tomb offerings, and overwhelming numbers of references from Hebrew Bible scriptures and innumerable writings from poetry, songs, literary publications, and many other surviving accounts of all civilizations in the ancient world. One of the earliest archeological evidences of apple tree fruit comes from the remains of excavations from Jericho, Jordan, that has been dated 6500 BC by radiochemical analysis of carbon atoms.

The petrified remains of apple slices that were found in a saucer of an ancient Mesopotamian tomb, the burial site of royalty dates back to 2500 BC and was uncovered in southern Iran. In the ancient historical accounts of the fruit of the apple tree, there appears to be an incomprehensible trail of evidence that no other fruit could match. The interest shown in apples by the Greek and Roman philosophers, poets, historians, and literary masters was even extended to Renaissance painters, royal chefs to the Tsars of Russia and too many other references to mention.

In colonial America, apple trees were grown and planted from seeds in orchards by William Blackstone at Boston, Massachusetts in the 1600’s. Early documents on file at the National Library in Washington, DC suggest that all land owners in Massachusetts had begun growing apple trees by the 1640’s.

William Bartram, the famous explorer and botanist, wrote in his book, Travels, “I observed, in a very thriving condition, two or three large apple trees” in 1773, while traveling near Mobile, Alabama. It is important to realize that these large apple trees found growing in Alabama in 1773 could very easily have been grown from the seed planted by Creek Indians. Those seed may have been obtained by the Indians from American colonists on the Eastern coast of the United States at a much earlier time or from French farmers who settles in areas of agricultural land grants north of Mobile. General Oglethorpe planned in 1733 to plant “various plants, subtropical and temperate, which might prove valuable for Georgian farms and orchards,” according to William Bartram in his book Travels, published 40 years later. William Bartram’s father, John Bartram, trip to “East Florida” (Florida, Georgia, and the Carolinas) was, in part at least, an attempt to inventory the plant resources of England’s new acquisition—after expelling the Spanish from East Florida.

Many modern botanists believe that the improved apple that we know today descended from the crabapple that is commonly interplanted with apple trees for cross pollination. Old documents record that fact “cultivated apples descended from crab-tree or wild apple-Pyrus malus.” Wild crabapple tree seeds appeared on the list of collected seeds in the Plant List of 1783 of William Bartram and his father, John Bartram. In William Bartram’s book, Travels in 1773, he “observed amongst them (fruit trees) the wild crab (Pyrus coronaria) in his explorations near Mobile, Alabama. Robert Prince established the first operating nursery in the American colonies at Flushing, New York, in the 1700’s, where he offered apple trees for sale at his nursery that was visited by General George Washington, who later became the first President of the United States. President Thomas Jefferson was planting and growing apple trees at his fruit tree orchard in Monticello, Virginia, in the early 1800’s.

The legendary Johnny Appleseed was responsible for the rapid development of the apple trees growing and planting when he established a nursery in the Midwest that sold both apple trees and seed to be planted for growing into trees in the 1800’s. Over 2000 cultivars of apple trees are listed as being grown today, many of the trees resulting from the huge apple seed dispersion that was begun by the memorable ambition of Johnny Appleseed to entirely cover the landscape of America with the fruit of apple trees.

Over the centuries, apple trees became susceptible to many disease problems such as fire blight; however, Dr. C.S. Crandall from the University of Illinois performed several backcrosses that involved modern cultivars and the apple tree ancestor ‘crabapple,’ Malus floribunda. The wild crabapple contained an immunity factor within its genetic composition towards all major bacterial and fungal diseases of apple trees. In 1989, researchers from the pomology department at Cornell University extracted an immune fire blight gene from a nocturnal moth and transplanted it into an apple fruit, resulting in the total defeat of fire blight in that particular apple tree cultivar.

Fruiting of apple trees is perhaps the most troublesome characteristic experienced by an orchardist or a backyard fruit tree gardener. Most cultivars of apple trees require cross pollination of two separate varieties in order to set fruit on the tree.

It is necessary that the blossoms of the two apple tree flowers develop pollen at the same time, in order that fruit will be set, which can be a tricky problem to correct. The simplist solution to pollinate apple trees is to use the ancestor of the modern day apple cultivars, the crabapple, which sheds its pollen over a long period of time and easily overlaps the apple tree cultivar flowering period. Crabapple trees produce a fruit that is much smaller than the common apple, but it can be used in cooking in various ways, and it is loved by wildlife in the fall and winter when wildlife food is scarce for animals and birds. Crabapple trees are also valuable when used as flowering trees that begin blooming in early spring with huge clusters of pink, white, and even red blossoms. Several outstanding grafted flowering tree selections are available, such as: Brandywine, Red Perfection, Radiant, and Spring Snow.

Apple trees are easy to grow, and if a gardener purchases a large tree, he may experience fruit development even on the first year of planting and growing. The selection of the proper cultivar of grafted apple trees is extremely important, because even though the apple fruit can be grown in most areas of the United States, the trees require different amounts of chilling temperatures in order to flower. The interesting introduction of low chill cultivars from Israel makes it possible to experience apple growing and planting as far south as Florida. Certain popularly grown cultivars of apple trees in the United States today are: Arkansas Black, Gala, Granny Smith, Red Rome, Anna, Red Fuji, Yates, Golden Delicious, Red Delicious, Anna, Ein Shemer, and Golden Dorsett. Apples contain some mysterious quality that can preserve it from deterioration for centuries. Apple slices can be dried and kept delicious for long periods of time. This mysterious characteristic may be recognized by man’s association of paradise being connected and related to Eve and Adam picking apples from a fruit tree growing in paradise for their eternal pleasure, that was planted by God and described as the tree of life at the fabled Garden of Eden. We see this fruit of paradise recurs in the history of many other ancient civilizations. A similar account that we read as children in the book of Genesis from the scriptures in the Hebrew Bible.

Perhaps this mysterious genetic quality of apples in preservation makes it so important as providing medical benefits backed up by that memorable proverb, “an apple a day keeps the doctor away.” Experiments from researchers in California have shown that apple fruit is very rich in antioxidants, a biological compound that combats, stroke, heart disease, and many other health problems.

Berries

One of the nation’s most well liked fruits; berries have origins in both Europe and here in the United States. The Native Americans were the first to incorporate berries into their diets and lifestyle. Today, berries are appreciated worldwide.

Berries signify summer and rightfully so, as the warmer months are the peak harvest for these fruits. Berries have traditionally included blueberries, strawberries, raspberries, and blackberries. However, there are other varieties that have since flooded the markets.

Many berries are suitable to eat raw and most types vary from 50 to 100 calories per serving if eaten raw. Berries are brimming with vitamin C, potassium, and fiber.


Varieties

Photo of blackberriesThere are many types of berries from smooth-skinned varieties like blueberries, to berries that have fleshy segments like raspberries and blackberries. Strawberries are not considered a ‘true’ berry, as they do not grow from a flower ovary but from the base of the plant.

Blackberries have a similar appearance to raspberries, but they are larger, hardier, and have a dark purple to black color. In general for this berry, the more intense color, the more sweet the fruit. There are blackberry hybrids that include boysenberries, loganberries, and ollalieberries, which are all, tart tasting and primarily used in jams and pies. Blackberry peak season is June and July with harvesting beginning in May and ending in September.

Photo of blueberriesWild blueberries are smaller in size compared to their cultivated cousins. Blueberries have a protective light powdery coating on the skins and tend to last longer than other berry varieties. Nearly half of the cultivated blueberries grown are sold as fresh blueberries. Fresh blueberries are available for nearly eight months of the year from producers across the United States and Canada. North America is the world's leading blueberry producer, accounting for nearly 90% of world production at the present time. The North American harvest runs from mid-April through early October, with peak harvest in mid-May—August

Currants are berries that look similar to grapes but are very tart. Because of their tartness, they are primarily used for jams and jellies. Red and white currants are grown domestically while the black currants are grown in Europe. Fresh currants are available July through August.

The most delicate of the berry family, raspberries have a similar structure to blackberries but have a hollow core. Therefore, this fruit requires delicate handling during preparation. Red raspberries are the most common type but there are also golden, amber, and purple berries all similar in taste and texture. Imported raspberries are from Chile, while most of the fruit comes from California. Raspberry season begins in June and lasts through October.

Perhaps the most popular of all the berries, strawberries have the most vitamin C of the berry family. Strawberries have been known since the time of the Greeks and Romans and cultivation of strawberries began in 1624. Commercial growing in America began about 1800 on the east coast of the United States. Strawberries moved west with the pioneers and now there are more than seventy varieties of strawberries, many of which are grown in California and Florida. This familiar fruit is usually available fresh year round with a peak from April to July.

Strawberries

Strawberries were mentioned in some Roman writings in the 200 BC time period. The French led the way in strawberry production after a French explorer brought the strawberry back to France from Quebec. The first breeding crosses made to improve the strawberry began in the 1800’s. Strawberries are native to both the northern and southern hemispheres. They are grown in every state in the US. Strawberries are visually stunning and they are produced in a variety of sizes, colors, flavors and shapes. The typical strawberries grown today belong to the genus Fragaria.

 The strawberry is very low in saturated fat, cholesterol, and sodium. They are a good source of folate, potassium, dietary fiber, vitamin C, and manganese. Because strawberries are universally loved for their taste, they are one of the major ingredients in a number of foods including ice cream, pies, yogurts, breakfast cereals, and of course, eaten fresh.

 There are many types of strawberries. The most common are June bearing or spring bearing plants. Another is the everbearing which produces fruits in the spring, summer, and fall. Finally, there is the day neutral strawberry that will produce throughout the growing season. The most important consideration for planting strawberries is choosing the site. The site must have excellent drainage and be in full sun. The soils should be tilled to a depth of 12 inches and good amounts of compost or well cured manure should be incorporated in the soil. The soil pH should be between 5.5 and 6.5 for best results.

Raspberries

Red raspberries were said to exist before the Romans came into power. The Romans initially spread the raspberry across Europe. The English took the raspberry and hybridized it and improved them during the middle ages. The English exported the plant to the United States in the 1700’s. The black raspberry is native to North America. Raspberries belong to the genus (Rubus). There are over 200 species of raspberries and the fruits are red, purple, black, yellow and orange. Botanically, the raspberry is not a berry at all, but is an aggregate fruit of numerous drupelets around a central core. Raspberries are harvested from early summer and into fall.

Raspberries have many uses. The leaves of raspberry plants are used to make herbal teas and they purported to be helpful for sore throats and stomach ailments. Raspberries contain antioxidants which helps promote cardiovascular health. They are rich in vitamin C and are a good source of soluble fiber. They contain less than 1 gram of fat per cup, very little sodium and no cholesterol. Raspberries are very tasty when eaten as a fresh fruit and they are excellent in jams, jellies, pies, and desert toppings.

Passion Fruit

An egg-shaped tropical fruit that is also called a purple granadilla, the passion fruit has a brittle, wrinkled purple-brown rind enclosing flesh-covered seeds, something like a pomegranate (granadilla means "little pomegranate" in Spanish). The seeds are edible so you can eat the orange pulp straight from the shell. Passion fruit is more commonly sieved and its highly aromatic pulp and juice are used as a flavoring for beverages and sauces. The pulp has an intense aromatic flavor, while the texture is jelly-like and watery. The flavor is likened to guava.

Native to Brazil, passion fruits are grown in Hawaii, Florida, and California. These crops, along with imports from New Zealand, keep passion fruit on the market all year.

Passion fruit is an excellect source of vitamins A and C. One passion fruit has only 16 calories. When eaten with the seeds, a serving is an excellent source of fiber.

Varieties

New Zealand Passion Fruit is purple while the Hawaiian variety is yellow.

Purple Form

Prune Trees

Prunes are European plum varieties with a high sugar content which is a trait that makes them suitable for sun-drying. Plums are native to China, America, and Europe. Today there are more than 200 cultivars being grown. There are two main types of plums, European and Japanese, being marketed today. Generally, Japanese plums are larger than European plums. European plums have high sugar content so they are often dried and used for making prunes. Japanese plums ripen earlier than European varieties.

 Most European plums will either benefit from or require cross-pollination from another European variety. Prune trees are fast growing and usually begin producing fruit in 3 to 5 years after planting. Prunes are rich in dietary fiber that is effective in improving digestion. They are low in calories and contain ample amounts of vitamin C, calcium, potassium, and carbohydrates.

Pomegranate Trees

Pomegranate trees are relatively fast growing fruit trees that produce a sought after fruit. Pomegranates have been under cultivation since ancient times. Pomegranates have been grown in India, Persia, Spain, and Germany, just to name a few countries. The tree was introduced to California by Spanish settlers in 1769. The pomegranate tree is attractive in the landscape and is long-lived. The flowers are showy and decorative.

Pomegranate fruits are quite unique. The fruit has a round, spherical shape and it is filled with dozens of small ruby-colored seeds. This fruit produces the delicious pomegranate citrus flavored juice that is universally acclaimed. Pomegranates are used for juice, jellies, pomegranate wine, and salad dressings. The pomegranate has a long storage life. It is best maintained at a temperature of 32° to 41° F. and can be kept for a period of 7 months within this temperature range and at 80 to 85% relative humidity without shrinking or spoiling. The fruits improve in storage, becoming juicier and more flavorful.

 Pomegranate fruit is low in saturated fat, cholesterol and sodium. It contains high amounts of vitamin C, calcium and iron. It produces dietary fiber and folate. Pomegranate fruit contains antioxidants which are purported to help protect blood lipids from oxidation.
